🔍 DNA Structure and Replication Notes – Key Concepts
DNA is a double-helical molecule composed of nucleotides (A, T, G, C)

Replication is semi-conservative (Meselson-Stahl experiment)

Enzymes involved: DNA polymerase, helicase, ligase, primase

Replication fork, Okazaki fragments, leading and lagging strands

🧬 DNA Replication in Prokaryotes – Initiation, Elongation, Termination
Prokaryotic replication occurs in organisms like E. coli and involves a single origin of replication (OriC).

🟢 Initiation:
DnaA binds to OriC

Helicase unwinds the DNA

SSBs (single-strand binding proteins) stabilize open strands

Primase lays down RNA primers

🟡 Elongation:
DNA Polymerase III adds nucleotides in 5’ to 3’ direction

Leading strand is continuous; lagging strand forms Okazaki fragments

DNA Polymerase I replaces RNA primers with DNA

🔴 Termination:
Tus proteins bind to Ter sites to stop replication

DNA ligase seals nicks between fragments

🧬 DNA Replication in Eukaryotes – Overview + PPT
Eukaryotic replication is more complex with multiple origins of replication (ARS in yeast) and more polymerases.

Key Differences:
Multiple origins of replication

DNA Polymerases α, δ, and ε

Presence of histones and chromatin remodeling

Telomere replication by telomerase
