Question

The process of copying genetic information from one strand of DNA into RNA is termed as :

• A. Replication
• B. Transcription
• C. Translation
• D. Reverse transcription

Hint:

Transcription occurs in the nucleus of eukaryotes, while replication occurs in the S-phase of the cell cycle.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The Central Dogma of molecular biology explains the flow of genetic information: DNA $\rightarrow$ RNA $\rightarrow$ Protein.
Step 2: Detailed Explanation:
Replication: The process of copying DNA to produce more DNA.
Transcription: The process of synthesizing RNA from a DNA template. Only one strand of DNA (template strand) is used.
Translation: The process where ribosomes synthesize proteins using the information in mRNA.
Reverse Transcription: Synthesis of DNA from an RNA template, typically seen in retroviruses like HIV.
Step 3: Final Answer:
The synthesis of RNA from DNA is called Transcription.
