Question

What are transposons?

Answer 1

Chromosomal segment that can undergo transposition especially, a sequence of bacterial DNA that can be translocated as a whole between chromosomal, phage and plasmid DNA in the absence of a complimentary sequence in the host DNA.

Answer 2

Answer :-

Transposon :-

• Transposon is defined as a D.N.A. segment or genetic element, which moves from one chromosome to another.

• Transposons occur in both eukaryotic and prokaryotic organisms.

• Transposons are present on bacterial chromosomes and on plasmids.

Extra Information :-

• The process of movement of transposons is termed as "Transposition".

• Transposition depends on the recombination of D.N.A. sequences.

• Transposons are autonomous units.

• Each transposon encodes an enzyme called "Transposase" that catalyses it's own transposition.

• The first transpositions were identified in the insertion sequences of E.Coli .
