  • Repeating sequence of bases on the ends of eukaryotic chromosomes that protect the DNA are called
    telomeres
  • Which enzyme unwinds the DNA double helix?
    helicase
  • Which enzyme builds the new DNA strand?
    DNA polymerase
  • What three components make up a nucleotide?
    sugar, phosphate, nitrogenous base
  • each new cell receives one old strand of DNA and one new strand, so DNA replication is
    semiconservative
  • What type of bond connects one nucleotide to another in a single strand?
    covalent bonds
  • which strand of DNA is made in one continuous piece?
    leading strand
  • Which enzyme adds the RNA primer?
    primase
  • What would the complementary DNA sequence be for this sequence: TGCA
    ACGT
  • Which enzyme builds the RNA primer?
    primase
  • What would the complementary sequence be for this strand of DNA: ATCCG
    TAGGC
  • The phosphate attaches to which carbon on the deoxyribose sugar molecule?
    5'
  • Which enzyme binds together Okazaki fragments?
    ligase
  • What did Watson and Crick figure out about DNA?
    DNA is a double helix
  • DNA strands run in opposite directions, so they are ___
    antiparallel
  • What type of bonds connects nitrogenous bases and holds double stranded DNA together?
    hydrogen bonds
  • What did Hershey and Chase conclude from their experiment with bacteriophages?
    DNA is the genetic material
  • DNA polymerase builds the new strand in what direction?
    5'-3'
  • During which stage of the cell cycle is DNA copied?
    interphase
