Which of the following is a CORRECT pairing of the RNA type and the description? 1. TRNA/contains codons which determine the correct amino acid sequence for a protein
2. mRNA/ formed from the DNA gene sequence with the help of RNA polymerase
3. rRNA/formed in the nucleus and carries amino acids to the ribosome 4.mRNA / contains anti-codons which are complements to tRNA codons

2. mRNA/ formed from the DNA gene sequence with the help of RNA polymerase

Explanation:

Ribonucleic acid, commonly known as, RNA, is one of the two nucleic acid biomolecule. Three types of RNA exists with varying functions viz: Transfer RNA (tRNA), ribosomal RNA (rRNA), and messenger RNA (mRNA).

- mRNA is a type of RNA that is formed from the DNA gene sequence during transcription with the help of RNA polymerase. It contains codons which determine the correct amino acid sequence for a protein.

- tRNA is a type of RNA formed in the nucleus, which contains anticodons (complementary to mRNA codons) that recognizes mRNA codons and carries corresponding amino acids to the ribosome.

- rRNA is a type of RNA that makes up bulk of the ribosome (organelles for protein synthesis).
