Which molecule delivers amino acids to ribosomes during translation?

Each tRNA molecule has two distinct ends, one of which binds to a specific amino acid, and the other which binds to the corresponding mRNA codon. During translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons.

What molecule transports amino acids to the ribosome quizlet?


Which molecule brings amino acids to the ribosomes to be assembled into proteins?

Transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins. In addition to tRNA there are two other major types of RNA: messenger RNA (mRNA) and ribosomal RNA (rRNA).

Which process is mRNA converted into a sequence of amino acid for protein production?

Key terms

Term Meaning
Transcription Process during which a DNA sequence of a gene is copied to make an RNA molecule
Translation Process during which an mRNA molecule is used to assemble amino acids into polypeptide chains
Mutation A change in a genetic sequence

What are the steps of translation that led to gene expression?

Translation involves four steps:

  • Initiation. The small subunit of the ribosome binds at the 5′ end of the mRNA molecule and moves in a 3′ direction until it meets a start codon (AUG).
  • Elongation.
  • Termination.
  • Post-translation processing of the protein.
