Answer:
e. Gain of function mutation in the p53 gene.
Explanation:
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Also, transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
In this scenario, you are reading a science fiction novel about a biotechnologically advanced society where individuals must choose a type of mutations for a future child to have in all its cells before they are born. As an expert biologist who wants a healthy child, you should choose a gain of function mutation in the p53 gene for your future child because they are clinically and biologically distinct.
