Which of the following correctly describes the process of synthesizing DNA from an RNA template using the enzyme reverse transcriptase?

1. Protein synthesis includes the stages of initiation, elongation, and termination. Transcription refers to the creation of RNA from a DNA template.
2. The process of producing DNA from an RNA template with the help of the enzyme reverse transcriptase is termed reverse transcription or teminism.
3. There are 64 codons in total, of which 61 specify amino acids. Each codon consists of three bases, and these bases can undergo either transition or transversion (61 × 3² = 549).
4. Nitrogen bases can exist in tautomeric forms, such as imino instead of amino (e.g., cytosine, adenine) or enol instead of keto (e.g., thymine, guanine). Tautomers are interconvertible through a process called tautomerization.

Correct answer: The process of producing DNA from an RNA template with the help of the enzyme reverse transcriptase is termed reverse transcription or teminism.

Solution

Option B is correct because reverse transcription is the process of synthesizing DNA from an RNA template using the enzyme reverse transcriptase, also known as teminism. The other options either describe unrelated processes or contain inaccuracies.
