Which is the biological importance of the molecule adenosine triphosphate (atp)?

It helps to provide chemical energy.

Explanation:

ATP: Adenosine triphosphate is known as the molecules of nucleotides. They help to transfer, and store energy within the cell. ATP also helps to synthesis of nucleic acids.

By the hydrolysis of 3rd phosphate group present in the ATP molecule energy is released. After the release of phosphate group the resulting adenosine diphosphate can absorb the energy, and gain the group. This process allow ATP to store energy.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
