    Study Notes

    RNA and Protein Synthesis

    • Messenger RNA (mRNA) is responsible for transferring genetic information from DNA to protein.
    • Transfer RNA (tRNA) carries amino acids to the ribosome during translation.
    • Codons in the genetic code function to specify the sequence of amino acids in a protein.
    • The elongation step of translation involves the formation of peptide bonds between amino acids.
    • The termination codon in translation signals the end of protein synthesis.
    • mRNA carries genetic information from DNA to protein synthesis.
    • Codons in the genetic code determine the sequence of amino acids in a protein.
    • Ribosomal RNA (rRNA) makes up the ribosomes.
    • The anticodon on tRNA recognizes and binds to the corresponding codon on mRNA.
    • During the initiation step of translation, the ribosome binds to the mRNA and the first amino acid is brought to the ribosome by the initiator tRNA.
