Question

DNA replication is an _________ process and ________ energy.
A. Exergonic; does not require
B. Endothermic; does require
C. Endergonic; does require
D. Endodontic; does not require
Solution:

Answer 1

Hint: When a cell divides, DNA copies itself through a process called replication. Deoxyribonucleic acid, also known as DNA, is a large molecule that houses our distinct genetic code. It contains the directions for generating every protein in our body, much like a recipe book.
Complete step-by-step solution:
Replication of DNA is self-complementary. Every cell's genetic makeup is encoded in DNA. Helicase is the first molecule that aids in the process.
The complementary bases of DNA, such as A with T and C with G, are separated by the hydrogen bonds that keep them together.
ATP, GTP, TTP, and magnesium ions serve as the DNA replication's energy sources.
In the presence of a polymerase, the energy generated by activated deoxyribonucleotide triphosphate also aids in polymerizing nucleotides and creating phosphodiester links between succeeding nucleotides.
Due to the formation of new bonds, DNA replication is an energy-intensive process. Therefore, they are endergonic, and the energy comes from dNTP.
Hydrogen bonding and base stacking interactions hold the DNA double helix together.
There must be some technology that helps to separate the two strands from one another if each strand is to be read and duplicated separately. This process is endergonic energetically.
Hence, option C is correct.
DNA replication is an endergonic process and does require energy.
Note: The opening of the double helix and separation of the DNA strands, priming of the template strand, and construction of the new DNA segment are the three main phases in replication. The DNA double helix's two strands uncoil at a precise spot known as the origin during separation.
