Homework Answers
Answer:
3). Ribosomal RNA
Explanation: Three types of RNAs directly involve in protein synthesis. Those are mRNA, tRNA & rRNA (ribosomal RNA).
4). Small nuclear RNA
Explanation:
Small nuclear RNA is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells
