Specific DNA sequences that have the ability to move within and out of chromosomes are called

A) transposons.
B) introns.
C) exons.
D) operators.
E) ribozymes.

Transposons

DNA sequences that can change their position within the genome, sometimes creating or reversing mutations and altering the cell's genome size.

DNA Sequences

The precise ordering of nucleotides within a DNA molecule, representing the genetic information of an organism.

Chromosomes

Thread-like structures located inside the nucleus of animal and plant cells, made of protein and a single molecule of DNA, carrying genetic information in the form of genes.
