Question

homework - protein synthesis
match the rna molecule with its corresponding function.
to supply appropriate amino acids for translation
to provide a template for the sequence of proteins needed
to provide the proteins needed for all cellular function
:: mrna (messenger rna) :: rrna (ribosomal rna) :: trna (transfer rna)

Explanation:

• tRNA (transfer RNA): It has an anticodon that pairs with the codon on mRNA and carries the appropriate amino acid for translation.
• mRNA (messenger RNA): It is transcribed from DNA and provides the template (with its sequence of codons) for the sequence of amino acids (and thus proteins) needed.
• rRNA (ribosomal RNA): Along with proteins, it makes up the ribosome. Ribosomes are the sites where protein synthesis (translation) occurs, and they help in providing the proteins (via translation) needed for all cellular functions.

Answer:

• "to supply appropriate amino acids for translation" $

ightarrow$ tRNA (transfer RNA)
