I want to PCR clone a gene from mRNA. I know about adding restriction sites to the primers but how far down from the stop codon should I look for a good primer from the mRNA sequence. i.e. what is the polyA tail sequence I should include in my PCR product?

I'm writing a lab report for a lab excersize testing for the presence of macromolecules... I'm trying to figure out what these substances could possibly be - you don't need to be sure, and I would be more than happy if you gave more than one possible answer for each substance. Just looking for ideas as it is 2 am and I am coming up blank.

Substance 1:
Tested positive for the presence of; Protein, Starch, and Sugar.
Tested negative for the presence of; Lipid.

Substance 2:
Tested positive for the presence of; Sugar.
Tested negative for the presence of; Protein, Starch, and Lipid.

Thanks for any help you can provide!

I am writing a story in which the principal character regularly handles dead bodies. Part of the plot premise depends on trying to alter the course of chemical changes the body goes through in the first weeks after death. But my college physiology courses were kind of hit-or-miss on post-mortem issues. If you have any books, links, or information about the changes the human body goes through in the first fourteen days after death I would be very appreciative and you would get ten extra points!

Imagine yourself meeting a person who seems very reasonable and cultured. You'd naturally think that whatever this person says is a reflection of the culture and intelligence you assume him to have. But when he begins to speak, even though you perceive no other change in his reasonable demeanor, he startles you with his incredible nonsense. He may insist that white is just a lighter shade of black, for example, or claim that the clouds in the sky are simply huge bunches of cotton. He believes things that no reasonable person with normal awareness and judgment could believe. He claims it is raining even though the sun is shining; and if you take him outside and show him the evident sunlight, still he persists in his claim that rain is falling and he even declares that he's getting wet! If you saw such a person, you could describe him in several ways. You might say he was being illogical, deluded, or even that he'd lost his mind, or even that he was crazy.

facilitated transport, diffusion, a difference in solvent concentration, a differentially permeable membrane, or more than one of these is correct.
