The proofreading function of DNA polymerase involves all of the following except:a. reversal of the polymerization reaction. b. phosphodiester bond hydrolysis. c. detection of mismatched base pairs. d. base pairing. a 3' - -> 5' exonuclease.

Why don't we use meters or miles when discussion distances between stars or galaxies?

I am having some trouble figuring out how to approach the following problem: A 75.0-mL volume of 0.200 M NH3 (Kb=1.8*10-5) is titrated with 0.500 M HNO3. Calculate the pH after the addition of 17.0mL of HNO3.

What is the mass of 3.75 moles of NaCI? (Na = 22.99g/mol, CI = 35.45 g/mol)

Convert to grams 0.100 moles of Co2

In order to use the value 22.4 L for molar volume in a mass-volume or volume-mass stoichiometry problem, the gas must be assumed to be at STP. A. True B. False

The gravitational attraction between two objects would increase if both masses are

If the pH indicator bromothymol blue was added to the nitric acid solution, it's colour would be?
