Q

Describe the process of DNA replication

A

DNA helicase breaks H2 bonds between complimentary bases
Allows unwinding of double helix
Free DNA nucleotides attracted to exposed bases & form complimentary base pairs through H2 bonding
A pairs with T and C pairs with G
Phosphodiester bonds formed by condensation reactions between adjacent free nucleotides
Catalysed by DNA polymerase
