|
DNA Replication is Semi-Conservative |
- both of the DNA molecules produced are formed from an old strand and a new one |
|
|
Unwinding of the Double Strand of DNA (DNA Double Helix) |
- first stage of DNA replication
- seperating them by breaking the hydrogen bonds between the bases - done by the enzyme helicase - each seperated strand is a template for the new strand - the free nucleotides form hydrogen bonds with their complementary base pairs on the template strand |
|
|
Base Composition and Pairing |
- DNA polymerase is the enzyme responsible - adenine will pair up with thymine and guanine will pair up with cytosine |
|
|
Result of Replication Process |
produced a new DNA molecule which is identical to the initial one |
|
|
Semi-Conservative Process and Complementary Base Pairing |
- the complementary base pairing allows the two DNA molecules to be identical to each other as they have the same base sequences - the new strands formed are complementary to their template strands but also identical to the other template |
|
|
Function of Helicase |
- unwinds the double helix and separates the two strands by breaking hydrogen bonds |
|
|
DNA Polymerase |
- links the nucleorides together to form a new strand, using the pre-exsisting strand as a template |
