This quiz reflects on the 'microbial genones' page of the Leicester University VGEC.

Resource summary

Question 1

Question
Human and bacteria organise their DNA (making up their [blank_start]genes[blank_end]) into [blank_start]chromosomes[blank_end]. Humans have 46 of them, whereas bacteria often only have [blank_start]one[blank_end]. Unlike in human cells, bacterial chromosomes are often [blank_start]circular[blank_end].
Answer
  • genes
  • chromosomes
  • one
  • circular

Question 2

Question
Bacteria can also have 'extra-chromosomal' pieces of DNA. Label both types of genetic material on the diagram below.
Answer
  • Chromosome
  • Plasmid

Question 3

Question
Eukaryotic genomes are far smaller than bacterial genomes.
Answer
  • True
  • False

Question 4

Question
The smallest bacteria genome is Mycobacterium genitalium, consisting of 580,070 base pairs.
Answer
  • True
  • False

Question 5

Question
The study of bacterial [blank_start]genomes[blank_end] has been made far easier by the development of DNA [blank_start]sequencing[blank_end]. DNA sequencing allows us to determine the [blank_start]base[blank_end] [blank_start]pairs[blank_end] making up a genome.
Answer
  • genomes
  • sequencing
  • base
  • pairs

Question 6

Question
Sequencing of entire bacterial genomes is extremely useful for two reasons: it allows us to predict the function of previously unidentified [blank_start]genes[blank_end] and it allows us to map the relationships of different bacteria to form a tree of [blank_start]life[blank_end].
Answer
  • genes
  • chromosomes
  • cells
  • bases
  • life
  • death
