A Science Odyssey: DNA Workshop: Replication - PBS

DNA replication is initiated at many points in eukaryotic chromosomes.

DNA replication (advanced detail) | HHMI BioInteractive

Using information from molecular research, this 3-D animation shows how DNA is replicated at the molecular level. It involves an enzyme that unwinds the DNA, and other enzymes that copy the two resulting strands. Also available in Spanish.

This process happens when the DNA Polymerase reaches to an end of the strands.

Let's simplify the last diagram, and assume that the whole copying process is complete. The next diagram focusses on the short bit of the total DNA molecule that we have been looking at. A typical human DNA molecule is around 150 million base pairs long - you will have to imagine the rest of it!

As a result, a part of the telomere is removed in every cycle of DNA Replication.

Enzymes like nucleases remove the wrong nucleotides and the DNA Polymerase fills the gaps.



Similar processes also happen during the steps of DNA Replication of prokaryotes though there are some differences.

6) The DNA Replication is not completed before a mechanism of repair fixes possible errors caused during the replication.

1)The first major step for the DNA Replication to take place is the breaking of hydrogen bonds between bases of the two antiparallel strands.

Animation: DNA Replication (Quiz 1) - McGraw Hill …

If you need detailed information about the replication of DNA, a Google search for will lead you to some well thought out and very clear animations of the process. The best one to start with can be found by following . This perhaps gives a better view of the over-all process, but is more difficult to understand if you don't look at the other one first. If you are an A level (or equivalent) chemistry student, only look at these if you are interested, not because you are likely to need it for exam purposes.

Eukaryotic DNA replication - Wikipedia

a)5'-3' Template: The 3'-5' proceeding daughter strand -that uses a 5'-3' template- is called leading strand because DNA Polymerase ä can "read" the template and continuously adds nucleotides (complementary to the nucleotides of the template, for example Adenine opposite to Thymine etc).

DNA Replication — bozemanscience

Both strands of the DNA double helix act as templates for the new DNA strands. Incoming DNA is unraveled by the enzyme helicase, resulting in the 3' strand and the 5' strand. The 3' strands and the 5' strands are replicated by a DNA polymerase enzyme but in different ways.
