bent science

I found a great site today for quick elucidation of sometimes complex ideas.

For example, read the following:

----------------------------------------

Pol III, the main DNA replication enzyme, cannot work in the 5' - 3' direction, and so replication of the lagging strand is more complicated than of the leading strand. On the leading strand, Pol III "reads" the DNA and adds nucleotides to it continuously.

On the lagging strand, primase "reads" the DNA and adds RNA to it in short bursts. Pol III lengthens the bursts, forming Okazaki fragments. Pol I then "reads" the fragments, removes the RNA, and adds its own nucleotides (this is necessary because RNA and DNA use slightly different kinds of nucleotides). DNA ligase joins the fragments together.

make sense? probably not

okay, now try this:

sorry for all the science-talk. I got exams soon. I got biochemistry on the brain.
