Question

Transposons:

विकल्प

• are specific DNA sequences that move within and between chromosomes

• alter the expression of neighbouring genes especially if the transposon is a regulator gene

• have been discovered in corn, fruit flies, bacteria, and humans

• all of the above

Answer 1

all of the above

Explanation:

Transposons are DNA segments that can migrate within and across chromosomes, hence the name “jumping genes”. They can change the expression of nearby genes, particularly if they insert into regulatory areas. These have been discovered in numerous organisms, including maize, fruit flies, bacteria, and humans.
