-- Posted by Anti at 2:59 am on Feb. 12, 2007 I was wondering is there a simple way of describe DNA replication so that it can be remembered for a test? I have looked all over the internet and i can not find anything to help me remember it. I remember some things but it doesn't sound technical could someone please help. -- Posted by JC at 3:13 am on Feb. 12, 2007 dna replication...i learnt about that last year...but months of heavy drinking soon fixed me up -- Posted by jakey at 3:38 am on Feb. 12, 2007 do you mean the process of meiosis? or mitosis? im confuzzled. but we've been doing that recently in A-Level Biology, so i'll try an give you a hand onece i know what you want.. -- Posted by Anti at 3:57 am on Feb. 12, 2007 Quote: from jakey at 10:38 pm on Feb. 12, 2007 do you mean the process of meiosis? or mitosis? im confuzzled. but we've been doing that recently in A-Level Biology, so i'll try an give you a hand onece i know what you want.. Mitosis -- Posted by jakey at 4:46 am on Feb. 12, 2007 there a several stages to mitosis, but there are less for this than there are for meosis so its all good. the first is called prophase, in this stage, in the nucleus all the chromatids (little sqwiggles) stop being a big mangled mess and pair up to make chromosomes. these then coil up and get shorter and fatter so we can actually see them. Then theres a stage called metaphase where the chromosomes line up along the middle of the cell, then things called spindle fibres pull on each chromatid making up each chromosome, and pull them in opposite directions so the split up and are no longer in a pair. So now there are two groups of chromatids, and around each of the two groups, a new nucluer membrane forms so you now have two nucleuses. so to summarise, the bits of dna pair up, then all of them line up along the middle of the cell, then they get pulled in half so there are two groups then a membrane forms around each group so you have two nucleuses now all this would be easier to explain with diagrams, but i hope that ive helped you a bit with this? thanks -- Posted by Anti at 12:48 pm on Feb. 12, 2007 Quote: from jakey at 11:46 pm on Feb. 12, 2007 there a several stages to mitosis, but there are less for this than there are for meosis so its all good. the first is called prophase, in this stage, in the nucleus all the chromatids (little sqwiggles) stop being a big mangled mess and pair up to make chromosomes. these then coil up and get shorter and fatter so we can actually see them.   Then theres a stage called metaphase where the chromosomes line up along the middle of the cell,   then things called spindle fibres pull on each chromatid making up each chromosome, and pull them in opposite directions so the split up and are no longer in a pair.

(ie the semi-conservative replication model?) -- Posted by Meep123 at 2:31 pm on Feb. 12, 2007 http://www.johnkyrk.com/DNAreplication.html That's what my AP Bio teacher used to explain it to us. You keep pressing next as it gives you a visual of the process, as well as the enzymes used with definitions along the right. -- Posted by killasamuri11 at 2:58 pm on Feb. 14, 2007 DNA replication thats the process of cloning the dna molecule for protein and ect.  Then putting that into another person or object correct so that it coppies it correct.
