Question

mobile genetic elements such as viruses and transposons continue to exist despite the fact that their activity would seem disrupt the fidelity of their hereditary material. This is because?

Answer 1

Transposons continue to exist despite the potential disruption they could cause due to several factors, including their insertion into non-coding regions, gene redundancy, and mechanisms that silence transposons. They can also increase genetic diversity.

Step-by-step explanation:

Transposons, such as viruses and transposons, continue to exist despite the potential disruption they could cause because of several factors. First, most transposition occurs in non-coding regions of the genome, which do not code for essential proteins.

Second, organisms have two copies of every gene, so if one copy is disrupted, the other can compensate. Third, mechanisms exist to silence transposons after they have transposed to mitigate the dangers. Mutations or small interfering RNAs (siRNAs) can render transposons inactive. Lastly, transposons can provide evolutionary value by increasing genetic diversity.
