Question

Complete the flow chart on central dogma.

$\left(\mathrm{a}\right)-\mathrm{DNA}\stackrel{\left(\mathrm{b}\right)}{\to }\mathrm{mRNA}\stackrel{\left(\mathrm{c}\right)}{\to }\left(\mathrm{d}\right)$

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

Answer 1

The correct option is D

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

The correct option is D.

Explanation for correct answer:

1. The central dogma is the process that depicts the flow of genetic information from DNA to RNA to form a functional protein.
2. Transcription is the process by which a DNA sequence is transcribed to an RNA molecule and produces a messenger RNA (mRNA).
3. The translation is the process by which an mRNA molecule is decoded to produce amino acids and used to synthesize a polypeptide.
4. During the expression of a gene to form a protein, information flows from the DNA to RNA and then to the protein.
5. Thus, central dogma is referred to as the directional flow of information.

Explanation for incorrect options:

Option A:

The order is incorrect.

Option B:

The order is incorrect.

Option C:

The order is incorrect.

Final answer: Option D is the correct answer.

Transcription - Translation

Replication - DNA -→ mRNA -→ Protein
