Question

What are transposable genetic elements? Who discovered them? In what plant were they first discovered? Why was this discovery so important?

Answer 1

Answer:

Transposable genetic elements are DNA sequence that can change it's position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size.

2) Barbara McClintock discovered them in 1948 . Even she was awarded a Noble Prize for this.

3) maize plants ( but I am not sure)

4) Because transposable elements make up a large fraction of the genome and are responsible for much of the mass of DNA in a eukaryotic cell.
