All about DNA:
Located at the nucleus
It is composed of 4 nucleotide bases namely, Adenine, Thymine, Guanine, and Cytosine and 5 carbon sugar and phosphate.
It consist of 2 base pairing, Adenine pairs with Thymine and Guanine pairs with Cytosine. These 2 base pairs form a ladder like structure with edges at the side called the sugar-phosphate backbone.
It is a double helix and is anti-parallel
Steps in DNA replication:
Hydrogen bonds break due to unwinding and separating of molecules.
The new(daughter) strand pairs with the old(parental) strand. Thus, a new base pair is formed.
Winding will occur as new nucleotides joined together by DNA Polymerase and resulting to a double helix.
