|The method of DNA replication is described as being __________
|The nature of DNA being semi-conservative ensures what?
|It ensures genetic continuity between generations of cells
|Describe roughly the first step in DNA replication
|DNA Helicase breaks the hydrogen bonds linking the two base pairs of DNA
|When the bases between the nucleotide bases are broken, what happens to the DNA Helix where DNA helicase has acted?
|The helix unwinds in to two non-linked strands
|When the two strands are exposed they are known as __________ strands
|After the nucleotide chains become template strands, what happens?
|free complementary DNA nucleotides are attracted to exposed bases on template strands and bind to their specific base pair
|After, nucleotides are joined together in what type of reaction? And by what enzyme?
|Condensation reaction by DNA polymerase. These form the 'missing' polynucleotide strand on each of the two original strands of DNA
|DNA replication is semi-conservative. What does semi-conservative mean?
|Each of the daughter DNA molecules contains one strand from the original DNA. So half of the DNA has been saved and built into each of the new DNA molecules.
