1 The helix in the double helix means that the entire thing is wound up in a spiral. 2  DNA composition: purine and pyrimidine bases, sugars, phosphate. 3  Nucleotide = base (Adenine, Guanine, Thymine, Cytosine) + sugar + phosphate. 4  Nucleoside = base + sugar = Adenosine, Guanosine, Thymidine, Cytidine.
Â¥Occurs in S phase of cell cycle. Â¥Process of DNA duplicating itself. Â¥Begins with the unwinding of the double helix to expose the. bases in each strand of DNA. Â¥Each unpaired nucleotide will attract a complementary. nucleotide from the medium. Ã° will form base pairing via hydrogen bonding. Â¥Enzymes link the aligned nucleotides by phosphodiester. bonds to form a continuous strand.
