Question

Retroelements use an _______ _______ in their transposition mechanism and two key enzymes: - _______ _______ - _______

Answer 1

Retroelements use an RNA intermediate, and two key enzymes, Reverse Transcriptase and Integrase, in their transposition mechanism. The RNA is copied into DNA by Reverse Transcriptase and placed into the genome by Integrase.

Step-by-step explanation:

Retroelements use an RNA intermediate in their transposition mechanism and two key enzymes, which are: Reverse Transcriptase and Integrase. The RNA intermediate is synthesized by the Retroelement, and then the enzyme Reverse Transcriptase copies this RNA into DNA. This newly formed DNA is inserted into the host genome by the enzyme Integrase. Thus, retroelements can create copies of themselves and insert these copies into new locations within the genome.
