Question

Complete the flow chart on central dogma.

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

• A. (a) - Transduction ; (b) - Translation ;
  (c) - Replication ; (d) - Protein
• B. (a) - Replication; (b) - Transcription;
  (c) - Transduction; (d) - Protein
• C. (a) - Translation; (b) - Replication;
  (c) - Tranascription; (d) - Transduction
• 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 given flowchart represents the central dogma of molecular biology which states that the genetic information flows from DNA to RNA to protein.

'a' represents replication, a process by which DNA makes copies of itself.
'b' represents transcription, a process by which genetic information from one of the strands of DNA is copied on to a strand of mRNA.
'c' represents translation, the process of polymerisation of amino acids to form a protein, which is represented by 'd'. The order and sequence of amino acids are defined by the sequence of bases in the mRNA.
