Principle of Inheritance and VariationHard
Question
A mutation at one base of the first codon of a gene produces a non- functional protein. Such a mutation is referred as
Options
A.framehift mutation
B.missense mutation
C.nonsense mutation
D.reverse mutation
Solution
Codons are found on mRNA. These are the key to the formation of genetic information and allow the synthesis of proteins. If mutation at one base of the first codon of a gene takes place then all the subsequent codons will be out of register (genetic code). This results the formation of missense protein which is formed due to mutation in the first base of first codon and thus called missense mutation.
