1. the enzyme dna polymerase works
only in the 5' to 3' direction. how does this
affect the leading strand and the lagging
strand?
c) a. dna polymerase can use only the
leading strand as a template. a different
enzyme is used to synthesize dna on the
lagging strand.
c) b. dna polymerase can work
continuously on the leading strand but works
discontinuously on the lagging strand,
creating okazaki fragments.
c) c. dna polymerase can work
continuously on the leading strand but must
flip the lagging strand around before it can
work on it.

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
