  • What are the base pairs of RNA?
    In RNA, adenine pairs with uracil, and cytosine pairs with guanine.
  • What is tRNA responsible for doing?
    tRNA is responsible for transporting amino acids to the ribosome and pairing its anticodon with mRNA codons.
  • RNA plays a role in which of the following?
    RNA plays a role in protein synthesis.
  • What are the features of the structure that forms when short regions of RNA form base pairs?
    Short regions of RNA can form secondary structures like hairpins and loops through base pairing.
  • RNA differs from DNA in all except which of the following ways?
    Both RNA and DNA are composed of nucleotides.
  • What are differences between DNA and RNA?
    DNA is double-stranded, contains thymine, and has deoxyribose sugar, while RNA is single-stranded, contains uracil, and has ribose sugar.
  • What are 2 differences between DNA and RNA?
    DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.
  • Which type of RNA functions to use coded instructions to assemble amino acids?
    mRNA functions to use coded instructions to assemble amino acids.
  • Which of the following types of RNA needs to have an amino acid attachment site?
    tRNA needs to have an amino acid attachment site.
  • Which of the following is a function of a tRNA molecule?
    A function of a tRNA molecule is to transport amino acids to the ribosome.
  • Prokaryotes and eukaryotes produce which of the following types of RNA?
    Prokaryotes and eukaryotes produce mRNA, rRNA, and tRNA.

  • How many different types of aminoacyl tRNA synthetases are there?
    There are 20 different types of aminoacyl tRNA synthetases, one for each amino acid.
  • Which base does adenine pair with in RNA?
    In RNA, adenine pairs with uracil.
  • Where would you find an anticodon?
    An anticodon is found on tRNA molecules.
  • Which of the following correctly describes the structure of tRNA?
    tRNA has a cloverleaf structure with an anticodon loop and an amino acid attachment site.
  • Which molecule carries an anticodon?
    tRNA carries an anticodon.
  • What are the base pairing rules for RNA?
    In RNA, adenine pairs with uracil, and cytosine pairs with guanine.
  • How are DNA & RNA different?
    DNA is double-stranded, contains thymine, and has deoxyribose sugar, while RNA is single-stranded, contains uracil, and has ribose sugar.
  • Which RNA molecule functions as an intermediary between an mRNA codon and an amino acid?
    tRNA functions as an intermediary between an mRNA codon and an amino acid.
  • What are the three different types of RNA?
    The three different types of RNA are mRNA, rRNA, and tRNA.
