Questions and Answers

Which type of RNA transfers amino acids to the ribosomes where proteins are synthesized?

  • DNA Polymerase
  • Transfer RNA (tRNA) (correct)
  • Ribosomal RNA (rRNA)
  • Messenger RNA (mRNA)

    • What is the function of ribosomal RNA (rRNA)?

  • Associates with proteins to form ribosomes and is the site of protein synthesis (correct)
  • Copies DNA's code and carries genetic information to the ribosomes
  • Makes up a long straight chain of nucleotides
  • Transfers amino acids to the ribosomes

    • Which part of a transfer RNA (tRNA) molecule has an attachment site for an amino acid?

  • Clover-leaf shape
  • Opposite end with an attachment site for an amino acid (correct)
  • The center region with a sequence of 3 bases called codon
  • Opposite end with three nucleotide bases called anticodon
