Cell Cycle

<p>

excellent 9 min video &nbsp;review of Cell Cycle...

v entertaining Southern accent!</p>

<p>

succinct... just hits the high points.</p>

<p>

g1 = gap1</p>

<p>

s = synthesis</p>

<p>

g2 gap 2...</p>

<p>

g1 is growth, new organelles, protein synthesis, enzymes, &nbsp;

this has a checkpoint...</p>

<p>

this is &nbsp;the normal phase of all cells... &nbsp;their normal metab in the body...</p>

<p>

*</p>

<p>

s-phase &nbsp;synthesis &nbsp;dna replication and normal protein syth slows down

but histones are produced &nbsp;(proteins that &nbsp;dna wraps around)</p>

<p>

leading strand and a lagging strand</p>

<p>

DNA polymerase III does the copying...</p>

<p>

helicase does the unwinding of DNA</p>

<p>

and single-strand binding protein &nbsp;keeps it open and keeps it from re-bidning to itself.</p>

<p>

&nbsp;G2 is growth in prep for division

and get synthesis of microtubules that will form spindle...

there is a safety check and a g2 checkpoint</p>

<p>

* m-phase &nbsp;mitosis &nbsp;

division of nucleus

PMAT &nbsp;prophase metaphase anaphase and telophase...</p>
