Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single day. Assume that a single mutation at a particular location in the virus A genome is needed for virus A to develop antiviral drug resistance to ledipasvir. The mutation can be a transition or transversion mutation. If RNA polymerase introduces an error in 1 of every 10,000 bases synthesized, how long will it take for virus A to overcome ledipasvir therapy and develop resistance? Round your answer up to a whole number of days.

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce:

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
