Formation of RNA from DNA is a process called:
Correct answer: A. Transcription
- A. Transcription
- B. Replication
- C. Translation
- D. None
Explanation
Transcription is the process by which an RNA molecule is synthesized from a DNA template. During transcription, the enzyme RNA polymerase binds to a specific region of DNA called a promoter and unwinds the DNA double helix. Then, RNA polymerase reads the DNA sequence and synthesizes a complementary RNA molecule, following the rules of base pairing (A-U, G-C). This RNA molecule is called messenger RNA (mRNA) and serves as the template for protein synthesis during translation.

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.
