Question

. Which of the following best describes the purpose of the hot water?

Clean the impurities from the wheat germ.

Dissolve the enzymes outside the nucleus.

Soften the membrane around the nucleus where the DNA is located.

2. Which of the following best describes the purpose of the detergent?

Clean the impurities from the wheat germ.

Soften the fats in the nuclear membrane so the DNA can be released.

Create a foam to activate the movement of the DNA.

Break down the enzymes in the nucleus that affect the DNA.

5. Predict what would happen if the water is too hot.

Answer 1

#1-Soften the membrane around the nucleus where the DNA is located

#2-Break down the enzymes in the nucleus that affect the DNA.

Answer 2

1) A - This is purely a guess, but I can rule out some of the others.  It's not B since fat is not soluble in water.  It's not C since the membrane is made up of proteins which aren't soluble in water, and it might be D depending on what concentration you need originally.

2) B - Soften the fats in the nuclear membrane so the DNA can be released.  Detergent's are used to release things..either DNA, RNA or proteins from Cells

3) D- DNA is insoluble in EtOH

4) These are your observations, I can't really tell you this answer

and 5) You'd most likely denature your DNA I'd believe

Answer 3

4 it is the shape of a "ladder", so what it looks like is a ladder twisted.
