Tekst Storyboardowy

  • Hi there, nice to meet you, what are you doing?
  • My name is Helicase, and I'm unzipping and unwinding this DNA double helix starting at the replication origin.
  • Replication origin
  • Tip: Remember Adenine and Thymine, with Apple and Tree.AND pair Guanine and Cytosine with Garage and Car.
  • Cool! I'm DNA Polymerase. need any help?
  • That would be great actually! Can you help replicate each strand of DNA by pairing adenine with thymine and guanine with cytosine?
  • Are you talking about Complementary base paring !!!
  • DNA Polymerase are adding all of the nucleotides to the leading strand.
  • The hydrogen bonds are the small beads at the end of the dna
  • 3'
  • They work, work, but one was lagging behind
  • 5'
  • 5'
  • 3'
  • We need to make sure Helicase and Primase are moving in opposite directions, 5' to 3' and 3' to 5'
  • My name is Primase, and I can add RNA primers to the lagging strand so that you can synthesize it.
  • Thanks a lot!
  • The DNA strand is Semi Conservative, as half is new and half is old
  • They worked together to synthesize the lagging strand. Primase added primers to sections of the strand, and then DNA Polymerase added nucleotides.
  • Lagging Strand of DNA
  • Primer
