Why is Serratia marcescens more susceptible to ultraviolet radiation than Bacillus cereus?

UV radiation exposure to S. marcescens colonies results in DNA mutations. The radiation energy is absorbed by the bacteria and if exposure is long enough, thymine nitrogenous bases adjacent to each other in DNA strands will form cyclobutane rings called thymine dimers. When replicating DNA and multiplying, the enzymes responsible for replication will bond a different base in place of the thymine bases and a mutation will result. How if affects the DNA, and consequently protein synthesis, is entirely dependent on the location of mutations.

What is bacillus alvei?
it is a honeybee bacillus
What part of speech is Bacillus?
Bacillus is a noun.
Why is bacillus subtilis able to grow after exposure to even 80 degrees Fahrenheit?
The simple answer is that Bacillus is capable of producing endospores. Endospores can withstand a wider variety of extreme conditions that would be harmful to other cells - such as radiation, abrasion, extremes of heat and cold, and lack of nutrients and water.
