Question

1. How does a retrotransposon move? It first produces transposase, which then binds the inverted repeats, and allows it to be removed from its original location and integrated into the genome at a new site. None of the above is correct. It first is transcribed into RNA, then a reverse transcriptase produces a DNA copy, and finally the DNA integrates into a new site. It first is transcribed into RNA, which is then translated into a protein that coats the RNA and allows it to attach to another genomic location, where it can be integrated during DNA replication. It first makes a DNA copy of itself, which is then transcribed into RNA, and finally the RNA is integrated into the genome.

Explanation / Answer

Answer 1c) It first is transcribed into RNA, then a reverse transcriptase produces a DNA copy, and finally, the DNA integrates into a new site.

Reason- In a retrotransposon, it required the mRNA to be the first reverse transcribe via a reverse transcriptase.further it ends up by integrating into the genome via the Integrase enzyme.
