Part of gene that is transcribed but NOT translated is __________.
Part of gene that is transcribed but NOT translated is __________.
Options
- Aexon
- Bintron
- Ccistron
- Dcodon
Correct answer
B. intron
Step-by-step solution
In eukaryotes, the structural gene is split into coding sequences called exons and non-coding intervening sequences called introns.
During transcription, both exons and introns are transcribed to form the primary transcript (hnRNA).
During post-transcriptional modification (splicing), the introns are removed and the exons are joined together to form mature mRNA.
The mature mRNA is then translated into a protein. Therefore, introns are the parts of a gene that are transcribed but not translated.
