There are 4 DNA The basic building block or monomer of DNA is the nucleotides: Adenine (A), Guanine (G). Cytosine (C), and Thymine (T). The name of the nucleotide depends on what part of the nucleotide? On the nucleotide illustration below: Label the 1, 2, 3, 4, and 5' carbons on the sugar of the nucleotide. Which parts of the nucleotides are involved when bonding two different nucleotides together? The 1' carbon is attached to what part of the nucleotide? The 5' carbon is attached to what part of the nucleotide? On the DNA double helix below: Phophodiester bonds are covalent bonds that link nucleotides together to form single strand of nucleotides. Designate with an arrow and label 2 examples of the phosphodiester bond. label the 5' and 3' ends of DNA strand #1 of the double helix. label the 5' and 3' ends of DNA strand #2 of the double helix. . Designate with an arrow and name the bonds that occur between the two strands of DNA, holding the two strands of the helix together. 0 -P-0-CH 0. Phosphate group strand #1 H-C H H H H OH H Sugar NH strand #2 N=C-H Nitrogenous base If you know the nucleotide sequence of DNA strand #1 of the double helix, how could you determine the nucleotide sequence of the strand #2, even if it wasn't provided?
