Which Molecules I needed to cut and copy segment in DNA
dimaraw [331]

Answer:

Biological catalyst has to be cut.

Explanation:

  • Enzymes are called "Biological catalyst".
  • Enzymes are called Biological catalysts because they diminish the activation energy for reactions. As the activation energy is reduced the rate of reaction is increased.
  • Many enzymes modify their state when substrates bind and it is known as "Induced fit".
  • Enzymes are nothing but Protein(Biological molecules). Most of the biological reactions are catalyzed by Protein.
  • Enzymes improve the rate of synthetic reactions without getting altered forever by the reaction.
