Which process does not occur during the formation of mRNA?
Correct answer: C. Replication
- A. Condensation
- B. Polymerisation
- C. Replication
- D. Transcription
Explanation
DNA replication is the process by which a ds-DNA molecule is copied to produce two daughter DNA molecules. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of mRNA. Both of these processes involve dehydration, condensation, and polymerisation of nucleotides. The process that does not occur during the formation of mRNA is replication. Replication is the process of making an exact copy of DNA, which is a separate process from transcription. During transcription, a complementary RNA molecule is synthesised based on a DNA template.

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.
