DNA polymerase adds nucleotides to the 3' end of the primer so the direction of replication will be?
Correct answer: A. 5' to 3'
- A. 5' to 3'
- B. 3' to 5'
- C. 3' end of the primer to 3' end of template strand
- D. 3' end of the template strand to the 3' end of the primer
Explanation
DNA polymerase is able to add nucleotides only in the 5′ to 3′ direction (a new DNA strand can be extended only in this direction). It also requires a free 3′-OH group to which it can add nucleotides by forming a phosphodiester bond between the 3′-OH end and the 5′ phosphate of the next nucleotide.

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.
