g DNA polymerase is used in PCR to cut DNA sequences into fragments that can then be inserted into vectors. true of false

False

Explanation:

The answer is False.

The DNA polymerase is an enzyme that adds nucleotide bases to the growing chain during the elongation process of DNA replication. It is also utilized in the Polymerase Chain Reaction process to synthesize and amplify the DNA of interest.

Polymerase Chain Reaction is primarily carried out to amplify a DNA of interest in order to be able to study it in careful detail. Cutting of DNA into fragments is carried out by restriction enzyme and this is only done during genetic engineering when a foreign gene is to be inserted into a genome.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
