Question

Select all the true sentences from the list below

-The essential viral genes are most likely to mutate over time

-The roughly regular mutation rate in viruses allowed scientist to estimate the origin of the covid-19 outbreak.

-The novel test CARMEN allows rapid screening of the population for hundreds of pathogens.

-The low mutation rate in viruses allowed scientist to estimate the origin of the covid-19 outbreak.

Answer 1

• The roughly regular mutation rate in viruses allowed scientist to estimate the origin of the covid-19 outbreak.

• The novel test CARMEN allows rapid screening of the population for hundreds of pathogens.

Are Correct Statements.

Explanation: Covid 19 is RNA virus. RNA genome mutates at faster rate than DNA virus. They have rough regular mutation rate. However, the essential viral genes are never mutated as they are necessary for survival. The novel test CARAMEN do allow rapid screening of the population for thousands of pathogens as it is based on CRISPR based molecular diagnostic technique.
