Question

Small nuclear RNAs are involved in

• A. Splicing of RNAs
• B. Splicing and processing of mRNA
• C. Splicing and processing of both rRNA and mRNA
• D. Binding of DNA

Answer 1

The correct option is C Splicing and processing of both rRNA and mRNA

Some RNAs, called small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs), are processed in the nucleus and are themselves part of the RNA processing systems in the nucleus. Most snRNAs are involved in mRNA splicing, while most snoRNAs are involved in rRNA cleavage and modification.

So, the correct answer is 'Splicing and processing of both rRNA and mRNA.'
