Which of the following components protects mRNAs from cellular nucleases?

Question

Quizplus · Accepted Answer

The 5'-GTP cap is a modified nucleotide that protects the 5' end of mRNAs from degradation by cellular nucleases. This cap also facilitates mRNA binding to ribosomes during translation. Introns are non-coding regions that are spliced out of pre-mRNA before translation and do not directly protect the mRNA from nucleases. Phosphorylation is a post-translational modification that can regulate protein activity, but it does not protect mRNA from nucleases. The TATA box is a DNA sequence in the promoter region of genes that helps recruit RNA polymerase to initiate transcription and does not protect mRNA from nucleases.
