If a gene moves to another location in the genome where, let's assume, no other gene was present, then the overall functionality of that animal remains unchanged?
It depends. Many places in the genome are not protein-coding, but contain regulatory information controlling when genes are on/off or how active they are when on. But, theoretically, if it didn’t disrupt anything when inserted, there could be no change in function.
@@BiologyProfessor , ok. I hv always wondered what if the human's genome all squeezed into say 10 chromosomes -- what is the significance of 23? (My answer to this: Whether 2 genes are in same chromosome or in different chromosomes, affects how independently those 2 pass on to next generation. So, fitting same genome in less number of chromosomes will affect (reduce) the diversity of that specie but not much else.) 2. What if the human's genome remained same, number of chromosomes remained same(23), but many genes shuffle between chromosomes. Afterall, when a gene is turned on or off, the activating agent within the cell fluid searches by the dna sequence of that gene, not by chromosome number or location within the chromosome. So the gene wherever it's present in those 23 pairs of chromosomes should be turned on or off. Please comment if my understanding is wrong.
rgudduu, If genes moved from one chromosome to another often, this would create big problems with meiosis and making gametes, because there would be cases of missing genes. Like, if gene A moved from one of the chromosome 1’s to one of the chromosome 2’d (reminder that cells are diploid and have 2 of each chromosome) then the gamete that got the chromosome 1 missing gene A and the *other* chromosome 2 that did not get gene A, would be missing that gene entirely! It could cause some real problems. Also, many genes have regulatory elements upstream and downstream. If the gene moved to a new chromosome, but left its regulatory regions behind, it would not function correctly.
This is complicated. Transposon scan in code a transposase enzyme because they are coding DNA. In other words transposon‘s are not non-coding DNA, although it is possible for them to be regulated by non-coding DNA and it is possible for them to combine to form non-coding DNA. But the transposon it’s self that encodes a transposase is not non-coding DNA. www.nature.com/scitable/topicpage/transposons-the-jumping-genes-518/
You are very beautiful.... and your videos are very helpful. Thanks for your existence. It would be very nice if you had more video playlists covering all major areas of biology and chemistry.
why does everyone keep saying shes beautiful (i'm not saying shes ugly or anything) but its a fucking science video U SHOULD BE SAYING TRANSPOSONS ARE BEAUTIFUL
your videos are gold
Thanks for all of the great informative videos
This was awesome! Thank you’
Excellent lecture......
Thanks!
Love Your Lecture !

Great work. Thank you so much.
madam iam ur fan man iam a Indian student
Thanks ,great job
thank you for video!!! i learnt everything:)
If transposon can encode for transposase enzyme why it is called as non coding DNA

weirdo
Good
super mam
i will watch every single video of yours /so pretty so soothing and so educational THANK YOU
Enjoyed it t
why does everyone keep saying shes beautiful (i'm not saying shes ugly or anything) but its a fucking science video U SHOULD BE SAYING TRANSPOSONS ARE BEAUTIFUL
What a queen
Thanks Whitney, you are awsome! And so incredibly beautiful!
👍
Too pretty to listen to ))
I love you mam
I'm really trying to concentrate but you're so pretty *-* (I'm a girl myself lol)
Did you lose a lot of weight?
I was pregnant in this video, but yeah. I lost my baby weight and then some with Keto.
