Test on Bacterial and Viral Genomics

Question 1: The smallest bacterial chromosome size observed is greater than 1 Mbp.

A. Ano

B. Ne

Explanation: The study materials state that the size of bacterial chromosomes ranges from 0.6 Mbp to over 10 Mbp. Therefore, the smallest observed size is 0.6 Mbp, which is not greater than 1 Mbp.

Question 2: What is the approximate size range of Bacterial chromosomes, according to the study materials?

A. From 0.5 Mbp to 5.8 Mbp

B. From 0.6 Mbp to over 10 Mbp

C. From 2.9 Mbp to over 4,000 Mbp

D. Approximately 3,451 kbps

Explanation: The study materials state, 'The size of Bacterial chromosomes ranges from 0.6 Mbp to over 10 Mbp.'

Question 3: Disastrous weather during the Little Ice Age in the late 13th and early 14th centuries had severe implications worldwide.

A. Ano

B. Ne

Explanation: The study materials indicate that at the end of the 13th century and into the first half of the 14th century, disastrous weather, known as the Little Ice Age, had severe implications worldwide.

Question 4: According to the study materials, what was the immediate population impact of the Black Death after it first arrived in Europe?

A. It killed off as much as 50 percent of the population in less than a decade.

B. It caused a 25 percent reduction in the population over several centuries.

C. It led to the death of nearly 75 percent of the population within five years.

D. It resulted in a 10 percent decline in population over the 14th century.

Explanation: The study materials state that the Black Death 'killed off as much as 50 percent of the population in less than a decade' after first coming to Europe.

Question 5: The protective dysfunctional 602S allele is common among individuals in Africa.

A. Ano

B. Ne

Explanation: The study materials indicate that the protective dysfunctional 602S allele is rare in Africa.
