Tell the dual purpose served by Deoxyribonucleoside triphosphates in polymerisation.
Answers
The dual purpose served by Deoxyribonucleoside triphosphates in polymerisation:
i. They act as substrates for DNA synthesis.
ii. They provide energy for polymerisation reaction. In a deoxyribonucleoside triphosphate the two terminal phosphates are high-energy phosphates.
They are the essential building blocks of nucleic acid and are necessary components of PCR mixes because no new DNA could be generated without them.
The Deoxyribonucleoside Triposphate act as both energy and substrate for the polymerisation reaction.
The Deoxyrebonucleoside Triposohate can be abbreviated as DTPs. It is considered as the building block of DNA synthesis.
The DTPs possess two high-energy phosphate that has the ability to provide energy to the replication by breaking their molecules.
It serves as a substrate that is consumed during the enzymatic reaction of replication.
Polymerisation is one of the noble process and the DTP is the only agent that have the ability to prevent mutation in the polymerisation reaction.
