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
