Q. Transposons are:

BHUBHU 2005

Solution:

Jumping genes or transposons are segments of DNA that can jump from one place in the genome to another place. Transposons were first discovered by Mc CIintock, in maize when she found a segment of DNA moved into gene coding for pigmented kernels. So as to result in light coloured kernels. Term "Transposons" was coined by Hedge and Jacob. Transposons change expression of genes and produce new genes and it's expressions.
