The replication of DNA is always from:
Correct answer: A. 5' - 3'
- A. 5' - 3'
- B. 3' - 5'
- C. Both
- D. None
Explanation
DNA replication proceeds in a directional manner, with new DNA strands synthesized in the 5' to 3' direction. This means that nucleotides are added to the growing DNA strand at the 3' end of the strand. DNA polymerase enzymes catalyze the addition of nucleotides to the growing strand, using the parental DNA strand as a template. The directionality of DNA replication is essential for maintaining the integrity and accuracy of the genetic information encoded in the DNA molecule.

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.
