A single base mutation in a gene may not 'always' result in loss or gain of function. Do you think the statement is correct? Defend your answer.
A single base mutation in a gene may not always result in loss or gain of function. We know that a codon Is composed of three nucleotides. In simplified terms, a codon can be taken as a word, which is composed of 3 letters. To make any meaningful sentence, we need a complete word. The addition or deletion of a single letter may not result In a meaningful word. Hence, in most cases, there is a need for a mutation in three bases to affect loss or gain of function. This can be illustrated by the following example of a sentence being altered:
RAM HAS RED CAP
RAM HAS BRE DCA P
RAM HAS BIR EDC AP
RAM HAS BIG RED CAP
It is quite clear that a meaningful sentence is made only when at least three letters are inserted in this sequence.
