    Together that's roughly it. The histone code is an idea that different combinations of different modifications to the histones, that DNA wraps around alters the chromatin structure and therefore affects gene expression.

    What is the difference between pulmonary artery pressure and pulmonary artery wedge pressure?
    What is PAWP used for?

    The first is innate, and the second is artificially applied? :) PAWP is used to constrict blood flow to promote blood clotting (to stop bleeding)?

    I'm thinking of them both as measurements. The pressure itself isn't used for anything.

    1) pulmonary artery wedge pressure is incorrect, Pulmonary wedge pressure as such, PAWP means nothing,

    2) PWP is a measure of pressure in the left atrial (albeit indirectly) and to see about Acute/Severe Pulmonary edema (acute pulmonary edema is the term used in the US, UK has a different one)

    3) Pulmonary artery pressure is used to gauge pulmonary artery hypertension

    Who invented both fishsticks and circuit boards?

    What was the first circuit board made out of (for extra credit)?

    You're the closest so I'll give it to you. Note, I actually meant who invented "printed circuit boards". It was Paul Eisler who invented them just prior to WW2 war, using etched, copper foil. First use was for a radio, and mid-WW2 the USA picked up on the idea of using them in field radios. After the war he was allowed to start his own company called Technograph that promoted their use. Before his invention, circuit boards were hand-constructed with solder.

    He continued to invent as a free-lancer, including inventing 'fish-fingers' (fishsticks).
    Do you like them?

    I'll ask a non-maths question while were waiting for a new one.

    Which Austrian-born Hollywood actress co-invented radio frequency hopping used in wireless networking, used in torpedoes originally (I think)?

    EDIT: I like fish fingers but not fish sticks.

    Apparently a character in Halflife 2 is named after this actress.
