Question

Refer the given sequence of steps and select the correct option.

• A. (i)-Replication, (ii)-Transcription, (iii)-Translation
• B. (i)-Replication, (ii)-Processing,
  (iii)-Translation
• C. (i)-Transcription, (ii)-Splicing,
  (iii)-Translation
• D. (i)-Transcription, (ii)-Replication, (iii)-Translation

Answer 1

The correct option is C (i)-Transcription, (ii)-Splicing,

(iii)-Translation
In eukaryotes, RNA is synthesized by copying the genetic information from DNA. This process is called transcription.
The RNA that is formed post transcription is called hnRNA (heterogenous nuclear RNA). hnRNA has introns and exons and it needs processing to form into functional mRNA. Processing includes splicing where in the introns (non coding sequences) are removed and later exons (coding sequences) are joined together.
This results in the formation of functional mRNA that moves to cytoplasm from nucleus and undergoes translation to form protein.
