After the 2 nucleotides have been broken What do the newly single strands act as?
Template for the synthesis of two double stranded DNA molecules identical to the original.
What does helicase do?
Unwinds the DNA and separates the double stranded DNA by breaking the hydrogen bonds between complementary base pairs.
What is DNA polymerase?
Type of enzyme that synthesis new strands from the 2 parental template molecules
In the environment of nucleoplasm what are there?
Many free-floating deoxynucleoside triphosphate
Nucleotides with 3 phosphate groups
What do the free-floating deoxynucledoside triphosphates do?
Align opposite their complementary base partner and covalently bond together with it
How are the free-floating nucleotides covalently bonded together?
Catalysed by the enzyme DNA polymerase which forms a complementary nucleotide chain
Draw an example of the double helix being unwound
Do it
What is the significance of complementary base pairing?
Each nitrogenous bases only pair with its complementary partner- therefore when DNA is replicated its 2 new strands will be identical to original strand
Draw an example of the new DNA with the 2 new strands.
Do it martha
