A50 î¼l pcr reaction contains two oligonucleotide primers. each primer is present in the pcr reaction at an initial concentration of 1î¼m.

a. how many moles of each primer are present in the pcr reaction?
b. how many molecules of each primer are present in the pcr reaction?
c. if the size of the pcr product in the above reaction is 500 bp, and the pcr reaction yields 2î¼g of the product, how many molecules of each primer are consumed by the pcr reaction?
hint: assume the average molecular weight of a nucleotide base pair is 650 daltons.
d. what ratio (percentage) of each primer was consumed by the pcr reaction

Osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? view available hint(s)osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? the first law of thermodynamicsthe difference in the height of water columns on either side of a selectively permeable membranethe difference in water concentration across a selectively permeable membranethe difference in sugar or ion concentration across a selectively permeable membrane

The theories on the expansion of galaxies maybe re-examined to strengthen science should not be tested to strengthen science will weaken scientific knowledge if they change will become laws if they don't change

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
