DNA Replication

Yay for operons!

back engineering is the greatest form of flaterey

is that murphey brown?

Most thing alive uses the same processus for replication. See from an evolutive point of view. Everything that lives has dna. for something to be alive, it must replicate dna in order to reproduce itself (reproduction is part of what defines life). So for life to happen, dna was first invented and then something to replicate it so life would last. although the molecule might not be exactly the same, the replication process is very similar for all species.

except for the nitrogen bases which makes each and every organism different the WAY the adenin matches with thymine, and guanine matches with cytosine.

Yes, the lenght of dna and number of chromosomes may vary from specie to specie and the sequences of nitrogen bases is very different even among the same specie, but the enzymes in charge of replication of the Dna are very similar for every living organism. The shape of the enzyme is not exactly the same and the sequence of amino acids may differ, but its very similar from one organism to another.

yepp, and im just a seventh grader:) teehee

i live ear the town in which the first real molecule of dna was first made by james watsion and crick. i went to a camp where its near the coldspring harbor labratories are, and on display there, they display the first real molecule. its a sshame, that rosalind franklin never really got any credit for the exray in which they found out that deoxyribonucleicacid was a double helix

metralios is quite right in his explanation. However, this reaction is only initiated when a cell needs to reproduce itself. Therefore, there is a right time for this reaction to happen. To control the timing, the cell adds an inhibitor (like an on/off switch) to the machine so the replication doesn't occur when it's not supposed to. An other chemical signal will remove the inhibitor when the cell the replication. This can get really complicated. There are often a lot of control molecule (switch

WOW!!!!
