-the process by which DNA makes a copy of itself
-occurs during interphase, prior to cell division

This animation shows how cellular proteins are built from the encoded instructions within DNA. Dec 21, 2007 Introduction. Deoxyribonucleic acid ( DNA) replication is a fundamental biological process that ensures duplication of the genome, and thus its propagation. The DNA structure has been described as a right‐handed double helix (B‐ DNA helix), which indicated that the DNA molecule was capable of self‐replication. DNA sequencing interactive game. Reconstruct a piece of DNA using the fragments above. We've given you the first piece. You do the rest. Chromosome mapping,dna markers,dna sequencing,2d animation,interactive game,fragments. Source: DNALC.DNAi. This 3D animation shows you how DNA is copied in a cell. It shows how both strands of the DNA helix are unzipped and copied to produce two identical DNA mole.

Steps of DNA replication

1. DNA helicase (enzyme) unwinds the DNA. The junction is called a replication fork.
2. DNA polymerase adds the complementary nucleotides and binds the sugars and phosphates. DNA polymerase travels from the 3' to the 5' end. The DNA is called the template strand.
3. DNA polymerase adds complementary nucleotides on the other side of the ladder. Traveling in the opposite direction.
4. One side is the leading strand - it follows the helicase as it unwinds.
5. The other side is the lagging strand - its moving away from the helicase (in the 5' to 3' direction).

Replication is called semi-conservative, because one half of the original strand is always saved, or 'conserved'

Problem: it reaches the replication fork, but the helicase is moving in the opposite direction. It stops, and another polymerase binds farther down the chain.

This process creates several fragments, called Okazaki Fragments, that are bound together by DNA ligase.

6. During replication, there are many points along the DNA that are synthesized at the same time (multiple replication forks). It would take forever to go from one end to the other, it is more efficient to open up several points at one time.

Replication Errors – can cause a genetic MUTATION
-- PROOFREADING by the polymerase prevents mismatches
-- DNA REPAIR ENZYMES can repair damaged DNA also
