Read the article to learn more about the types of RNA, specifically mRNA and tRNA. Use the information to answer the following question.

RNA

Explain the roles of mRNA and tRNA in protein synthesis.
- mRNA (messenger RNA)
- Carries the genetic instructions copied from DNA into a linear sequence of codons (triplets of nucleotides). Each codon specifies one amino acid (or a stop signal).
- In eukaryotes mRNA is processed (5′ cap, splicing, poly-A tail) and exported from the nucleus to the cytoplasm; in prokaryotes it is often translated directly.

mRNA is transcribed from DNA.

The nucleotides in mRNA code for amino acids.

tRNA translates the mRNA sequence into an amino acid sequence so proteins can be made.

Explanation (brief):

- mRNA: Transcribed from DNA, processed in eukaryotes (5′ cap, splicing, poly-A tail) and exported to the cytoplasm. It carries the genetic instructions as a linear sequence of codons (triplets of nucleotides); each codon specifies an amino acid or a stop signal. The ribosome reads the mRNA codons as the template for protein synthesis.
- tRNA: Small adapter molecules that carry a specific amino acid and have an anticodon that base-pairs with the mRNA codon at the ribosome. By matching anticodons to codons, tRNAs bring the correct amino acids in sequence so the ribosome can join them into a polypeptide.
