Which of the following is a function of snRNAs?

B) They transport amino acids to the site of protein synthesis.
C) They combine with proteins to form ribosomes.
D) They transfer mRNA from cytoplasm to the nucleus.

Question

Quizplus · Accepted Answer

SnRNAs (small nuclear RNAs) are involved in the splicing of pre-mRNA, which is the process of removing introns and splicing together exons to create the mature mRNA transcript. This occurs in the nucleus of eukaryotic cells, and snRNAs work in conjunction with other proteins to form the spliceosome, which carries out the splicing reaction. Therefore, choice A is the best answer as it accurately describes the function of snRNAs.
