DNA Structure & Replication

forms base pair with cytosine

• thymine

• adenine

• guanine

check all of the parts of a nucleotide

• base

• protein

• sugar

• phosphate

name of the sugar found in DNA

• ribose

• deoxyribose

• nitrogenous

credited with discovering structure of DNA

• Chargaff

• Franklin

• Watson & Crick

The building blocks of DNA

• monosaccharides

• RNA

• nucleotides

• enzymes

breaks hydrogen bonds to unzip two strands of DNA during replication

• DNA polymerase

• DNA helicase

• ligase

the products of DNA replication

• one DNA molecule with 2 original strands + one DNA molecule with two new strands

• two DNA molecules - each with one old strand and one new strand

• two DNA molecules - each with 2 strands made up of old and new parts

adds free/new nucleotides to the exposed bases during replication

• DNA polymerase

• DNA helicase

• ligase

make up the rungs of the ladder in DNA

• sugar

• phosphate

• base

check off all of the bases found in DNA

• thymine

• uracil

• adenine

• guanine
