• A. $\begin{array}{ccc}\left(i\right)& \left(ii\right)& \left(iii\right)\\ \text{Replication}& \text{Transcription}& \text{Translation}\end{array}$
• B. $\begin{array}{ccc}\left(i\right)& \left(ii\right)& \left(iii\right)\\ \text{Replication}& \text{Processing}& \text{Translation}\end{array}$
• C. $\begin{array}{ccc}\left(i\right)& \left(ii\right)& \left(iii\right)\\ \text{Transcription}& \text{Splicing}& \text{Translation}\end{array}$
• D. $\begin{array}{ccc}\left(i\right)& \left(ii\right)& \left(iii\right)\\ \text{Transcription}& \text{Replication}& \text{Translation}\end{array}$

Answer 1

The correct option is C $\begin{array}{ccc}\left(i\right)& \left(ii\right)& \left(iii\right)\\ \text{Transcription}& \text{Splicing}& \text{Translation}\end{array}$

Synthesis of RNA from DNA is called transcription and formation of mRNA from hnRNA by removal of introns is called splicing. Whereas synthesis of proteins according to coded information of mRNA is called translation.

$DNA\stackrel{\left(Transcription\right)}{\to }hnRNA\stackrel{\left(Splicing\right)}{\to }mRNA\stackrel{\left(Translation\right)}{\to }Proteins$
