DNA Structure

Comparison of DNA forms (Fig. 4.6).
DNA bending (Fig. 4.7).
Denaturation and renaturation (Fig. 4.8).

Melting curve (Fig. 4.9a)
Circular DNA denaturation (Fig. 4.10).
Circular DNA supercoiling (Fig. 4.11).

DNA Synthesis

During DNA synthesis nucleotides are added to the 3' end of the DNA by a polymerase enzyme that recognizes a coplementary base on the template strand of DNA. Therefore the DNA synthesis is always in a 5'->3' direction (Fig 4.16).
