a. the dna molecule will supercoil.
b. no replication fork will be formed.
c. replication will occur via rna polymerase alone.
d. no proofreading of the replicated strands will occur.

The energy of blowing wind can be harnessed to create electricity. why is wind considered a renewable energy source? a) wind does not cause destruction of the environment.b) wind turns the blades of a windmill that creates electricity.c) wind provides only a very small amount of electricity to the united states.d) wind comes from atmospheric conditions that are available indefinitely.

Why would a drug the damages capsids treat a viral infection

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
