Retroviruses are RNA-based viruses that infect cells. During infection, they incorporate their genome into the host’s DNA. How are retroviruses able to incorporate DNA into a host cell?
A) Retroviruses translate their RNA into proteins, which bind to the DNA of the host to cause latent infection.
B) Retroviruses directly inject their RNA-based genome into the host’s DNA, resulting in high levels of mutations.
C) Retroviruses use their single stranded RNA to bind to the host’s single stranded DNA to prevent the host’s DNA from replicating.
D) Retroviruses can use their own reverse transcriptase to make a DNA copy from an RNA template before incorporating DNA into the host’s genome.

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.
