DNA replication- Great Video!

Before a cell divides, it duplicates its DNA in a copiying process called replication. This process ensures that each resulting cell will have a comlete set of DNA molecules. In mitosis, This happens during interphase in the S phase.
DNA replication is carried out by a series of enzymes.

I can't believe nobody picked up on the fact that she said this completely backwards! DNA replicates from the 5 prime end to the 3 prime end on the leading strand and the Okazaki fragments occur on the lagging strand because it's 3 prime to 5 prime and DNA replicates from 5 prime to 3 prime!

@IslandBlossom I did say that the okazaki fragments occur on the lagging strand, you have to listen carefully.

They are MnMs!

hey look skitties

I don't think you should say 'great video' in your title - that's for us to decide.  :-)

Das ist so schon kompliziert und jetzt auch noch auf Englisch und mit furchtbarer Musik...

@IslandBlossom replication and reading are different. Polymerase READS from 3' to 5' but REPLICATES from 5' to 3'. She correctly stated that the strand is READ from 3' to 5'.

yummy! I feel hungry :)

[ivynnivana]

Ey i think u made a mistake, my teacher says it moves from 5 prime to 3 prime not the other way round

[xMercyful]

You also forgot to say that first DNA Polymerase 1 comes in and glues the Okazaki fragments together, then the DNA ligase comes and fixes the last phospho bond.

@fyishrad95 but @IslandBlossom is right, your orientation is off. Replication occurs from 5' to 3'. Important not to forget, especially when dealing with techniques like PCR!

You sound like from Arab or India ?

That being said, the video helped me alot.  Thanks for making it. :D

@IslandBlossom Thanks. I just went "WAT?" then looked down and saw your comment.
