What is a gene?


Stated Clearly presents What exactly is a gene? What exactly is a gene? each one of our cells contains 46
strands of DNA. A single strand is made up of millions of
particles called nucleotides. Nucleotides come in 4 different types which scientists have labeled A C T and G A gene is a special stretch of DNA: a sequence of As Cs Ts and Gs, that codes for something. a gene contains information for a cell to read
but what exactly does that information do? a gene contains information for a cell to read
but what exactly does that information do? You might have heard that there’s a blue eye gene, a freckle gene, and possibly even in anger gene, but single
genes don’t literally make things like eyeballs are freckles or temper tantrums. Genes make proteins. Genes make proteins. Those proteins then interact with each other and all sorts of other chemicals inside the body to build things like freckles, eye pigments, and mood altering hormones. A single strand of DNA contains
thousands of genes or unique protein recipes. Humans have roughly twenty thousand
all together. Some genes are small, only about three hundred letters long, others are well over a million. The length and sequence of a gene determine the size and shape of the
protein it builds. The size and shape of the protein,
determine the function that protein will have inside the body. Hemoglobin for example, is a protein
structure found in red blood cells. Its unique shape and size allowed it to
capture oxygen molecules when blood flows near the lungs, and then release them later when blood
flows near oxygen starved tissues. Pepsin is a digestive protein. Its unique shape allows it to break down
food inside your stomach so it can be absorbed by the body. Keratin is a structural protein its unique shape and size allow it to
link together with other karatin proteins to form hard structures like
fingernails, claws and beaks. Different creatures have different genes
which is ultimately why their bodies look and
function differently, but one of the many reasons scientists
believe all life on earth is related is that the basic DNA code, the language of As Cs Ts and Gs, is pretty much the same for all living
things. Many creatures even share some of the
same genes. You may not be too surprised to learn
that humans and chimps (which are closely related) You may not be too surprised to learn
that humans and chimps (which are closely related) share about ninety six percent of their
genetic code, but what would you think that a lowly fruit fly has in common with a
beautiful swimsuit model? surprisingly, about half of its genes. about half of its genes. Because all creatures use DNA in
pretty much the same way, genetic engineers have found that they can
take the gene from say a bacteria cell, and inserted into the DNA of an
animal or plant cell. That animal or plant cell will read the
gene and produce the bacterial protein. Engineers have mixed and matched the
genes or many different organisms to produce many new creatures, including corn that is toxic to insects but
supposedly safe for human consumption, tomatoes that last up to twice as long and
the grocery store before going bad, and a new form of bacteria that produces the human protein insulin,
which we then collect from these bacteria and give to people with diabetes
who need extra insulin to survive. So just to sum things up a bit, So just to sum things up a bit, What exactly is it gene? A gene is a special stretch of DNA, not an entire strand of DNA, justice a segment, that codes for something. Each gene is like a unique recipe which
usually tells a cell how how to make a protein or a group of proteins. Different creatures have different genes, but all genes are written in the same
basic DNA language of As Cs Ts and Gs of As Cs Ts and Gs of As Cs Ts and Gs I’m Jon Perry, and that’s Genes, Stated Clearly.

  1. You made an awesome video. I came here because I was talking to my 4yr old about genetic modification, he asked me 'what is a gene' and I didn't know how to answer it in a way that he would even begin to understand. He doesn't completely comprehend everything we just watched (he's 4 so, yeah) but he's already asking me if we can watch more stuff to explain other things. Subbed and grateful. Thank you so much. You never realize how hard it is to describe something until you have kids and you have to define everything, ever.

  2. Mainstream genetics has it's applications but no creation science genetics has any applications. It clearly stays withing the confines of pseudo science and mainstream genetics demonstrates that creation science genetics is just a theory (and will remain that way). If you think creation science genetics has it's applications, then what do they teach genetic students before they graduate?

  3. My God, You are..this is… I just… I love You man, I was so desperate before exam, that I type in Youtube DNA for dummies. Best decision ever. Thank you so much :*

  4. LOL, crying about the GMO stuff… The most wrong thing he said was that Chimps and Humans share 96% of their genetic code. He should have said, "If you only compare a cherry picked 2.4 billion Human Bases to a hand assembled COPY of Human DNA with a few pieces of strategically inserted Chimp DNA, which was also only 2.4 billion base pairs in length…then sure, they were 96% similar. The fact that the "sequenced genomes" that were compared, in no way represents either a Human or Chimp should be disregarded and the lie that Humans and Chimps are genetically similar should be repeated as often as possible.
    This is how science works.

  5. Hi. Just wanted to say my science obsessed autistic 8 year old loves your videos! Thank you for putting this in a format he can understand!

  6. 2 years ago i saw this video and i didn't get anything but today i saw it again and i got everything thanks to God i can see improvement in myself 😊😊

  7. Bere bere interesting. I thik i fould seing Harambi again was very interestig. Also i like how it says click to sub in the right botterm corner but when you click it nothing hapens. Humans are 96 precent like apes, so why desnt eeryone love bananas. I guess thats why people say. The most butiful thing ive ever seen, a BANANA

  8. I found this channel yesterday and I have not been able to stay away. Amazing work!!! I will be watching this with my nephews and nieces over the christmas holidays. Thanks for making me the cool uncle 🙂

  9. If only they were A C D F or something so you could translate the full genetic code of something from hexadecimal to decimal/binary and just use it to program a software which translates it back so that you can 3D print a housefly or shrew or something like that.

  10. Would love to show this video in class… is there a version without the weird sexual vibes towards the swimsuit model?

  11. That off handed "supposedly safe" comment about GMO foods is highly inappropriate as the science is settled and GMOs have been proven to be COMPLETELY SAFE for consumption. I hope you put an annotation to that stating the same. We have enough of conspiracy theorists as it is.

  12. thank u so much making such an informative video….my all concepts are made more clear after watching this video….keeo it up and plz .make more videos like this

  13. Which of the molecules listed below is NOT a nucleotide that makes up DNA? *
    1 point
    Adenine
    Guanine
    Thymine
    Zytozine
    Cytosine

  14. I do not get if dna is a twisted ladder how they are found in the nucleus ? is it a long double strand or many small ones

  15. Thank YOU! That answers the question I have been asking for a while. I have a lot of questions. Please tell me exatl;y what were Marx`s prescriptions for a better way of organizing society. Did he merely list the faults of Capitalism or did he actually make suggestions or prescriptions? Both the political right and the political left have muddied up the subject.

  16. What exactly is a Gene?
    –> A Gene is a special stretch of DNA not the entire strand of DNA just a segment that codes for something.

    –>Each Gene is like a unique recipe which usually tells the cells how to make protein or a group of proteins.

    –>Different creatures have different genes but all genes are written in the same basic DNA language of A's,C's,T's and G's.

  17. This one is a little confusing at 0:23 as it shows the DNA split apart but then it makes it look as though A interlocks with C and T interlocks with G. As you know, A combines with T and C with G, so it would have been clearer to have the 4 nucleotides displayed in the same sequence that they’re in on top of the ladder, with the red and blue together on top and then the yellow and green on bottom.

  18. One of the best explanations I've encountered. You guys are undoubtedly aware that the brain best recalls the first and last, and in that way you summerise it all in a clear language at the end. Thank you!

  19. You say 96 percent of the human genes resemble that of chimps genes, but I think although it's true, it might be misleading. You know A and B are related but there's no way to know whether A caused B or B caused A or something else cause both of them. We can't say whether our very similar genetic code means we have been once chimps or whether this similarity is just because we were supposed to be created similar to each other! In more technical terms: "Correlational studies can only tell us whether variables are related to each other—they cannot lead to conclusions about causality". -Statistics in Plain English.

  20. You are wrong

    Gene is a Epic Brawler who can grab enemies with his magic lamp, also he has an annoying voice.

  21. This video is super helpful I watched a few other videos and it helped me pass my science test with 51/60! That’s the highest score I’ve ever got! So thank you soo much

  22. these are what genes look like https://www.alpinestars.com/media/catalog/product/cache/image/800×800/e9c3970ab036de70892d86c6d221abfe/c/o/copper_denim_darkrinse.jpg

  23. Your explanations are really clear!! If you'd like to, I think it's gonna be really good to widen your fields like posting some videos on physics or chemistry 🙂
    I'm enjoying your videos so much anyway!

  24. Hmm but it's just a bunch of nucleotides. Where does one gene end and another begin? What exactly separates them?

  25. At the 10 second mark, you mention, "Each one of our cells contain 46 strands of DNA." It's actually 92 strands of DNA. DNA is a double helix. So there are two strands of DNA for each molecule of DNA.

  26. These are awesome and really well done. My only critical feedback for this episode, is the "beautiful swimsuit model" comment. Would be great if we could move on from viewing women this way; that's not something I want my young daughter seeing and thinking about. Otherwise, nice job!
