6. Students taking an exam are divided into two groups, P and Q such that each group has the same
number of students. The performance of each of the students in a test was evaluated out of 200

standard deviation of group P was 25, while that of group Q was 5. Assuming that the marks were
distributed on a normal distribution, which of the following statements will have the highest
probability of being TRUE?
(A)  No student in group Q scored less marks than any student in group P.
(B)  No student in group P scored less marks than any student in group

1. Bacteria with two or more flagella at one or both ends are called
(A) amphitrichous        (B) peritrichous            (C) lophotrichous (D) atrichous 
Answer: (C) 
Exp: Monotrichous bacteria have a single flagellum (e.g., Vibrio cholerae). 
o Lophotrichous bacteria have multiple flagella located at the same spot on the bacteria's
surfaces which act in concert to drive the bacteria in a single direction. In many cases, the
bases of multiple flagella are surrounded by a specialized region of the cell membrane,
the so-called polar organelle. lophotrichous (lo-fot ri-kus) [lopho- + Gr. thrix hair]
having two or more flagella at one or both ends; said of a bacterial cell
o Amphitrichous bacteria have a single flagellum on each of two opposite ends (only one
flagellum operates at a time, allowing the bacteria to reverse course rapidly by switching
which flagellum is active).
o Peritrichous bacteria have flagella projecting in all directions (e.g., E. coli).
2. Which family of viruses has single stranded DNA?
(A) Herpesviridae         (B) Poxviridae (C) Retroviridae  (D) Parvoviridae 
Answer: (D) 
Exp: Although bacteriophages were first described in 1927, it was only in 1959 that Sinshemer 
working with phage Phi X 174 showed that they could possess single-stranded DNA genomes. 
Despite this discovery until relatively recently it was believed that the majority of DNA viruses 
belonged to the double-stranded clade. Recent work suggests that this may not be the case with 
single-stranded viruses forming the majority of viruses found in sea water, fresh water, sediment, 
terrestrial, extreme, metazoan-associated and marine microbial mats. Many of these 
"environmental" viruses belong to the family Microviridae.
[11]
 However, the vast majority has yet 
to be classified and assigned to genera and higher taxa. Because most of these viruses do not 
appear to be related or are only distantly related to known viruses additional taxa will be created 
for these. Families in this group have been assigned on the basis of the nature of the genome 
(circular or linear) and the host range. Eleven families are currently recognised. 
o Family Anelloviridae
o Family Bacillariodnaviridae
o Family Bidnaviridae
o Family Circoviridae
o Family Geminiviridae
o Family Inoviridae
o Family Microviridae
o Family Mycodnaviridae
o Family Nanoviridae
o Family Parvoviridae
o Family Spiraviridae
