In semi-conservative replication, which of the following is true regarding the separation of two strands?
Correct answer: A. Primary structure is conserved, and secondary structure is disturbed
- A. Primary structure is conserved, and secondary structure is disturbed
- B. Secondary structure is conserved, and the primary structure is disrupted
- C. both the primary and secondary structures are conserved
- D. Both the primary and secondary structures are disrupted
Explanation
In semi conservative replication, the original molecule is unzipped; each strand of the duplex becomes a part of another duplex. During the separation of two strands, the primary structure is conserved while the secondary structure is disrupted.

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.
