Question

Name and explain the process the RNA molecule transcribed from 8000 nucleotide-long DNA undergoes to be able to translate a polypeptide of 400 amino acids.

Hint:

Splicing ensures the formation of functional mRNA by removing non-coding sequences, enabling accurate translation.

Answer 1

Process: Splicing. Explanation: Messenger RNA precursor (pre-mRNA), transcribed from DNA, comprises both coding sequences (exons) and non-coding sequences (introns). Splicing involves the excision of introns and the ligation of exons, resulting in mature mRNA, which subsequently directs protein synthesis.
