I'm a Premed student and can't understand genetics anywhere more than from your channel. You are amazing! I wish you make more videos on higher-level, enhanced and new genetic concepts for students of master of genetic counseling and geneticists.

The easiest way to understand is certain gene expresses eye color. Allele is the actual color like brown, black, or blue. I hope that helps to those who are confuse.

I wanted to ask a question to clarify some simple concepts. We always hear that we have two copies of every gene (one from father and another from mother). When we say that, do we mean the 5-3 strand and 3-5 strand double stranded DNA? Or do we mean that there are actually two copies of the gene, each having its own 5-3 strand and 3-5 strand?
@aadirimal80815 жыл бұрын
When polypeptides are being synthesized, is the template equally likely to be from the maternal or paternal chromosome or is there a difference in probability? Does it even matter? It should, in cases of heterozygotes with one abberant allele e.g. Tay Sachs disease, shouldn't it? How does one chromosome get chosen, from which a protein is to be made when there are always two options? Or is it that both maternal and paternal chromosomes contribute?

I have a doubt, when you say you have A on your gene and T on my gene (two alleles), the A it is not supossed to be together with another pair of base on my gene? How it is a allele? Because T and A are pair of bases. I don't know if you can understand my question.

This video should be compressed to be 2 minutes long. 75% of the content is him saying the same thing over and over again.. IN exactly the same way, which is to say, he's saying it in exactly the same way, the same way he says it before. Over and over, about what his image is referring to. the image he's pointing to, is the same way, as the other things. Over and over again. So what I'm trying to say, is that the video should be shortened because he's saying the same things too many times. Which is to say he needs to cut that out because it's too repetitive.

This speaker has made many videos, and knows what he's doing. He is very smart. Good teachers know that repetition helps learn, and that explaining the same thing 4 ways might help 4 students understand the subject each step of the way. Also, it might just be his manner of speaking. Also, his priority with this video is to help people understand what he's talking about. He is not concerned with the fact that many students will find this video "rudimentary" and a waste of their time - he is concerned that many students would not understand the video if he were to just say, "Gene = section. Allele = flavour of section". Also, most of his repetition occurs while he is drawing, and his drawing helps visual learners. Also, he talks about more than just the basics of genes and alleles. He talks about mRNA, tRNA, rRNA, transcription, translation, X and Y chromosome determining gender (which many forget nowadays), etc. Altogether, I understand your criticism and think it is somewhat valid, but it is a good idea to see things from the speaker's perspective, and from less-intelligent viewers' perspectives as they gain a lot out of this video

How is self replicating RNA may be the basis for all complex life on earth different from a tornado ripping through a junkyard and producing a 747 jetliner? Love the information but i think your premise is flawed. Our creator/designer gave us all the necessary tools to live forever in a vast uncharted Universe and some try and look the other way. Sad to see, but in the end. Your non belief has actually helped us understand our Universe in a more logical and productive way. So in the end it all works out how it was intended. If everyone thought the same and had the same beliefs we would never be able to debate and figure out the truth together. Everything is the way it is for a reason and i feel we will eventually figure out the answer or force an intervention.
