DNA elements, which can switch their position, are called:
Correct answer: B. Transposons
- A. Cistron
- B. Transposons
- C. Exons
- D. Introns
Explanation
DNA elements that can switch their position are called transposons. Transposons are mobile DNA sequences that can move from one location to another in the genome. They can be short or long sequences, and they can be either coding or non-coding.The other options listed are not DNA elements that can switch their position:Cistron is a unit of heredity that codes for a single polypeptide chain.An exon is a coding region of a gene.An intron is a non-coding region of a gene.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
