In the process of semi-conservative replication:
Correct answer: A. Primary structure is conserved
- A. Primary structure is conserved
- B. Secondary structure is conserved
- C. Primary structure is changed
- D. Primary structure is disrupted
Explanation
In the process of semi-conservative replication, the primary structure is conserved. The primary structure of DNA refers to the sequence of nucleotides along the DNA strand, and this sequence is faithfully maintained in the newly synthesised DNA strands. Each original DNA strand serves as a template for the synthesis of a complementary strand, preserving the primary structure. The secondary structure, which is the double helical structure, is disrupted temporarily during replication but is reformed as the new strands are synthesised.

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.

In semi-conservative replication, the two strands of duplex separate out, each acting as a _ or _ along which nucleotides are arranged thus giving rise to two new duplexes:
_ codons do not bind to tRNA, but they are recognized by release factors:
The movement of the ribosome on mRNA translocates the initial tRNA to the _ site and ejects it from the ribosome:
The conservative model of DNA replication stated that the parental double helix would _ and generate DNA copies consisting of entirely new molecules:
In this model of DNA replication parental DNA would become completely dispersed and each strand of all the daughter molecules would be a mixture of old and new DNA:
