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.

The options for this question are:

- Requires genetic variation

- Results in descent with modification

- Involves differential reproductive success

Answer:

<u><em>The correct option is d) All of the above</em></u>

Explanation:

The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
