What fraction of the human genome consists of transposons and retrotransposons?

Short Answer

Expert verified

The fraction of the human genome that consists of transposons and retrotransposons are 3/100 and 2/3 respectively.

Step by step solution

01

Transposons

Transposons, specifically DNA transposons, are transposable elements that don’t involve any intermediates and account for approximately 3% of the human genome. However, in most cases, they are inactive.

02

Retrotransposon

Retrotransposons are those genetic components that exhibit transposition through a pathway similar to the replication of retroviruses. They account for about two-thirds of the human genome.
