Understanding DNA Replication

Mechanism of DNA Replication

• The process of DNA replication is described as semi-conservative, meaning each new DNA molecule consists of one original strand and one newly synthesized strand.

• The double helix structure of DNA is introduced, highlighting the phosphate backbone and the nitrogenous bases that extend outward.

• An enzyme initiates the replication by unwinding the double helix, allowing for the synthesis of complementary strands based on existing templates.

Base Complementarity in DNA

• A reminder about base pairing: adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).

• The hydrogen bonds between bases are discussed; A-T pairs have two hydrogen bonds, whereas C-G pairs have three.
