Front

What is the function of integrase in retrotransposons?

Back

It cuts the DNA where the transposon will be inserted.

Front

Define transposase.

Back

An enzyme that facilitates the movement of transposons within the genome.

Back

Jumping genes.

Front

What is the significance of junk DNA in the human genome?

Back

It may play roles in regulation and genome structure, despite not coding for proteins.

Front

How do exons differ from introns?

Back

Exons are coding regions of a gene, while introns are non-coding regions.
