Which scientific term best matches this description: A region that resides within a gene but does not remain in the final mature mRNA molecule following transcription of that gene and does not code for amino acids that make up the protein encoded by that gene?

A) Monosomy

B) Nucleolus

C) Intron

D) Nucleosome

Answer: C

Explanation: An intron is a region that resides within a gene but does not remain in the final mature mRNA molecule following transcription of that gene and does not code for amino acids that make up the protein encoded by that gene. Most protein-coding genes in the human genome consist of exons and introns.
