Noncoding Sequences Found in Eukaryotic Genes That Interrupt the Coding

Question

Noncoding sequences found in eukaryotic genes that interrupt the coding sequences are known as:
A) Introns
B) Exons
C) Spliceosomes
D) Pre-mRNA
E) None of these

Accepted Answer

Noncoding sequences found in eukaryotic genes that interrupt the coding sequences are known as introns. Exons are the coding sequences that are spliced together after the introns are removed. Spliceosomes are large molecular complexes responsible for removing introns and splicing exons together. Pre-mRNA is the initial transcript of a gene before it is processed to become mature mRNA.
