I hope this helps. Happy studying. :)
Potential energy is stored in energy in an object or system and kinetic energy is when the object is in motion
Answer:
c. Taq polymerase is heat-stable and can withstand high temperatures.
Explanation:
The process of PCR amplifies a small amount of DNA into multiple copies. For the purpose, the sample DNA fragments are denatured at higher temperature conditions (around 95 degrees Celsius). This separates the two strands of the sample DNA which in turn serve as a template. Taq polymerase from a thermophile can withstand the extremes of the temperature conditions required for denaturation of sample DNA. Unlike the DNA polymerases from other organisms such as humans, Taq polymerase is not denatured at higher temperatures.
Therefore, Taq polymerase can be used as an enzyme of primer elongation to amplify the DNA by PCR.
irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.
