The reaction mixture for pcr is missing the enzyme taq polymerase. which step of pcr would this affect?

The missing of Taq DNA polymerase will affect the DNA synthesis or polymerization step.

Explanation:

Taq DNA polymerase is also known as termostable DNA polymerase because it is able to exert its catalytic activity at high temperature.

     Taq DNA polymerase is used for the 3rd step of polymerase chain reaction which deals with the joining of nucleotides by phosphodiester bond formation.

     The missing or lack of Taq DNA polymerase will affect the DNA synthesis step of PCR.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

i believe the correct answer is d
