An unknown sample has been given to you and you must enumerate the phage load. You begin your investigation by serially diluting a sample resulting in the following dilutions: 10-2, 10-4, and 10-6. You spread 100 µL of 10-2 and 10-6 dilution onto a separate nutrient agar plate and incubate for 48 hours. Upon examining your plates, you observe the following results:  10-2: 100 PFU,  Calculate the phage titer for the plate in PFU/mL.   

Prokaryotic mRNA is monocystronic, while eukaryotic mRNA is polycistronic.

The Cre-Lox system involves which type of conservative site-specific recombination?

Which of the following is TRUE regarding translocation during translation?

In your lab, you found that rapidly growing cancer cells duplicated the telomerase gene and modified that new copy (telomerase B). These two telomerase genes (telomerase A and telomerase B) are an example of
