Answer:
The mutations that were found in the parents were mostly somatic mutations
Explanation:
It has been mentioned in the question that leukemia was mainly found in the persons who were directly exposed to the radiation and it was absent in their children so this fact suggests that the mutations that were found in the parents were mostly somatic mutations and thus they are not transferred to the children from their parents. As these mutations were induced due to exposure of radiation so it was induced mutation. And such induced mutations do not get inherited to the offspring.

Answer:
The correct answer is- transcription regulation
Explanation:
Transcription regulation is a process by which a cell controls the conversion of DNA into protein-coding mRNA. Transcription regulation is important to conserve energy by making active proteins only when they are needed. It occurs both in prokaryotes and eukaryotes.
In prokaryotes, operons are found which have operator region that regulates the transcription of mRNA transcript having structural genes. Binding of repressor protein on operator inhibits the initiation of transcription.
In eukaryotes, RNA polymerase requires transcription factors and several proteins to function therefore these factors regulate gene transcription in eukaryotes. So the right answer is transcription regulation.
