Description
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
