DNA Replication


Dna replication1

DNA Replication

  • Replication = DNA copies itself exactly

    • (Occurs within the nucleus)

  • Any mistake in copying = mutation

  • DNA mutation = chromosomal mutation


A basic facts of dna replication

A. Basic Facts of DNA Replication

1. Complementary base pairing

makes replication possible

C - G

A - T

2. One side of DNA molecule is

a

template

for

making

the

other side (strand)

B process of dna replication

B. Process of DNA Replication

  • Uncoil & unzip DNA molecule

    • Enzyme (-ase) breaks

      weakHydrogen Bond

      between bases
