Summary Introduction
To determine:
The three ways by which transposable elements are thought to contribute to genome evolution
Introduction:
Transposable elements also known as transposon are the sequence of DNA that can change its location within the genome. This may create or reverse some mutations and also alter the genome size and genetic identity of the cell. They make up a large portion of the genome responsible for majority of DNA mass in eukaryotic cell, but play an important role in the functioning of genome and evolution.
