Dna replication

DNA Replication

Honors Biology


Dna base pairing

  • A will always bond with T

  • C always bonds with G

  • It is estimated that humans have more than 3 billion base pairs in each cell.

DNA Base Pairing


Structure of dna

Structure of DNA


Dna replication1

  • Replication of DNA occurs to create new stands of DNA or to correct or replace mutated DNA.

DNA Replication


Dna replication2

  • DNA replication starts with an enzyme called Helicase, The Helicase separatesthe Hydrogen bondsthat are in between the two complementary bases. This acts like a zipper

DNA REPLICATION


Dna replication

  • The DNA polymerase binds to a single strain of the old (parent) DNA, and uses it as a template to makes a new chain.

  • The result is a new strain that is half old half new.
