Question

Complete the flow chart on central dogma.

• A. (a)-Transduction; (b)-Translation;(c)-Replication; (d)-Protein
• B. (a)-Replication; (b)-Transcription; (c)-Transduction; (d)-Protein
• C. (a)-Translation; (b)-Replication; (c)-Transcription; (d)-Transduction
• D. (a)-Replication; (b)-Transcription; (c)-Translation; (d)-Protein

Answer 1

The Correct Option is D

The central dogma of molecular biology describes the two-step process by which the information in genes flows into proteins: DNA → RNA → Protein. Let's complete the flow chart based on this concept. 

1. \((a)\) is Replication: This is the process by which DNA is copied to produce identical DNA molecules. It occurs in the cell nucleus and ensures the genetic information is preserved for cell division.
2. \((b)\) is Transcription: This is the process where the DNA sequence is copied into mRNA. Transcription occurs in the nucleus.
3. \((c)\) is Translation: This is the process where the mRNA is used as a template to synthesize proteins. It occurs in the ribosome in the cell cytoplasm.
4. \((d)\) is Protein: This is the final product of the central dogma. Proteins perform various functions essential for life.

Therefore, the correct sequence describing the central dogma is:

• (a)-Replication
• (b)-Transcription
• (c)-Translation
• (d)-Protein

This corresponds to the correct answer: (a)-Replication; (b)-Transcription; (c)-Translation; (d)-Protein.
