Thanks for this series. I am about 45 years past my biology degree but enjoy refreshing my knowledge with your videos. Back in my university days we only really had professors and texts but videos like yours, coupled with YT, makes learning so much more enjoyable. Many thanks!!
@ROBO MATIC Wow all the best.... So you're from India right? India has been one of the countries I ever wished to study Medicines at..... We've some Indians fellow students here with us too.
It is called degenerate because the number of codons are more than the number of amino acids.. the word degenerate means something low.... here number of amino acid is less than the number of codons..
Degenerate is a terrible word, a better description is redundant. Redundancy makes genetics more reliable, notice that a mutation on the 3rd nucleotide would often result in no consequences as the amino acid being coded for does not change. Redundancy saves us from mutations in other places, double stranded DNA allows simple mutations to be easily fixed, 2 sets of chromosomes allows a gene to function when the other copy is dysfunctional.
