  • Hello, my name is Rosalind Franklin and I discovered how to make x-rays clearer for the DNA molecules.
  • Today we will be talking about the basics of DNA replication and how it functions.
  • The replication process then happens when the polymerase attaches the one parent strand to a new daughter strand which creates your DNA. It can also be described as "proofreading".
  • DNA replication is a necessity for us because without it, we wouldn't look the way we do. It's what makes us look like our parents.
  • DNA replication happens in a stage called interphase. It begins when the helicase unzips the strands of DNA from the parent molecule.
  • But the strand can never be completely new, it always has to be one parent strand and one new strand. This is why DNA is semi-conservative. When it is semi-conservative, it always has to take a strand from the parent, it can't be just a new strand because you wouldn't have any of the similarities passed down.
  • The polymerase can also combine the sugar and phosphate together to combine nucleotides together.
