The hydrolysis of the pyrophosphate in DNA replication is
a. a mutation.
b.
endergonic.
c.
exothermic.
d.
energetically neutral
e.
exergonic.
During the DNA replication process, the pyrophosphate is released and is hydrolyzed. Due to the hydrolysis of the pyrophosphate the energy is released which is used to bind the incoming nucleotide in the replcication process. The formation of the phosphodiester bond is an endergonic reaction.
The answer is A.
The hydrolysis of the pyrophosphate in DNA replication is a. a mutation. b. endergonic. c. exothermic....

What is genetic mutation? How should they be corrected during DNA replication?
To study DNA replication, researchers often use bacteria that harbor a temperature sensitive mutation in one of the genes related to replication. This means that when cells are grown at lower temperatures (30°C) they are fine, but when shifted to 42°C the effect of the mutation becomes evident and that protein is no longer functional. Depending on the gene mutated, researchers observe that for some replication stops almost immediately, but for others more slowly. In this question you have a...
ATP hydrolysis is highly ______ because it involves ______. A. Exergonic; separation of negatively charged phosphate groups B. Exergonic; alteration of the transition state C. Endergonic; breaking of covalent bonds D. Endergonic; removal of a phosphate group forming phosphoric acid, which decreases the pH
11. A mutation occurs when i) hydrolysis of a glycosidic bond releases a purine or pyrimidine base. ii) homologous DNA strands undergo recombination. iii) DNA polymerase inserts the wrong nucleotide during replication. iv) damaged DNA is not repaired before the cell divides. v) All of the above
