Question: 121. Complete the flow chart on central dogma.
(a) CDNA \xrightarrow{(b)} mRNA \xrightarrow{(c)}(d)
(1) (a)-Replication; (b)-Transcription; (c)-Transduction; (d)-Protein
(2) (a)-Translation; (b)-Replication; (c)-Transcription; (d)-Transduction
(3) (a)-Replication; (b)-Transcription; (c)-Translation; (d)-Protein
(4) (a)-Transduction; (b)-Translation; (c)-Replication; (d)-Protein
Answer: Option (3)
Explanation:
The central dogma of molecular biology explains the flow of genetic information in a cell.
DNA can make an identical copy of itself by the process called replication.
The synthesis of mRNA from DNA is known as transcription.
The synthesis of protein from mRNA is called translation.
Thus, the correct sequence is DNA replication, transcription to form mRNA,
and translation to form protein.
Therefore, the correct completion of the flow chart corresponds to option (3).
