Answer:
b. Enzymes always change their shape when they bind to a molecule.
d. An enzyme’s shape is related to the shape of the substrate it binds to.
Explanation:
Enzymes are proteins that are secreted by special cells in living organisms. They are the organic catalysts of biochemical reactions.
The role of the enzyme in the enzyme catalyzed reaction is to bring reactants together on its surface so as to have better interactions.
Enzymes have the capability to fit the substrate into an induced fit position.
The process by which enzymes change shape in a reaction is called the induced fit.
This way an enzyme holds the substrate tightly for the reactions to occur.
The question is asking to choose among the following choices that states the enzymes that should be use to join the sticky ends of the gene and the plasmid, And in my own observation, I would say that the answer would be Ligase. I hope you are satisfied with my answer and feel free to ask for more
