You are characterizing a new dna polymerase. when the enzyme is incubated with [32p]dna and no dntps, you observe the release of [32p]dnmps. this release is prevented by adding unlabeled dntps. which of the following describes the reactions that most likely underlie these observations?

a)the dna polymerase contains 3'-5' and a 5'-3' exonucleases that degrade dna to produce [32p]dnmps.
b)the dna polymerase contains a 5'-3' exonuclease that degrades dna to produce [32p]dnmps.
c)the dna polymerase contains a 3'-5' exonuclease that degrades dna to produce [32p]dnmps.
d)any of the above could explain these observations.
e)none of the above.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
