What provides the energy for synthesizing dna strands in pcr?
a. atp added to the pcr mix
b. a charge current
c. dntps
d. charge repulsion

The correct answer is C dNTPs

Explanation:

The deoxyribonucleotides which are added during PCR provides energy for synthesizing DNA strand .

            The energy is generated by the breakdown of the terminal phosphate group or gamma phosphate group from the participating deoxyribonucleotides.

           The hydrolysis of the terminal phosphate of deoxyribonucleotides generates energy for the joining of two adjacent nucleotides along DNA strand by phosphodiester bond formation. This result in the arrangement of deoxyribonucleotides along the two template DNA strands thereby helping to synthesize new DNA strand during PCR.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
