Answer:
Component of ribosomes: Ribosomes are organelles involved in the protein synthesis they made up of r-RNA and proteins.They play a role in the alignment of amino acids during protein synthesis.
Used in degrading mRNA: SiRNA is small synthetic RNA molecule used for gene silencing experimentsIt is the 18-25bp length and it binds to its complementary m-RNA and degrades it.
Brings amino acid to ribosome:t-RNA is called transfer RNA because it transfers amino acids during protein synthesis. Each amino acid is carried by its particular t-RNA molecule.
Processing of mRNA & Processing of rRNA: Sn RNA is small RNA molecules involved in the splicing and processing of RNA molecules they are located in the nucleus.
Contains codons:m-RNA are intermediate molecules of DNA and protein synthesis and they carry a message regarding the sequence of amino acids. The message carries in the form of codons.
