Name and explain the process the RNA molecule transcribed from 8000 nucleotides long DNA undergoes to be able to translate a polypeptide of 400 amino acids.
Show Hint
RNA splicing is essential in eukaryotes to produce functional mRNA for protein synthesis by removing non-coding sequences.
Introns (non-coding regions) are removed, and exons (coding regions) are joined to form a mature mRNA strand.
This process reduces the RNA length to 1200 nucleotides, ready for translation.
