True
False
Which of the following is not included in the three domain system?
Eubacteria
Peptidoglycan
Archaea
Eukarya
Archaea bacteria can live in extreme conditions due to ester-containing linkages.
True
False
Polyphasic taxonomy consists of phenotypic and genotypic classification.
True
False
Which of the following is not true about polyphasic taxonomy?
To determine the genus and species of a newly discovered prokaryote
Integrates several accepted ideas for the classification of bacteria.
Involves phenotypic & genotypic approaches for bacterial classification
Phenotypic approach is sufficient to infer evolutionary relationship
Which of the following is not a phenotypic trait?
Colony morphology
Cell shape and cell wall
G+C rich content
Biochemical characteristics
Genotypic classification aims to compare the observable and genetic similarity between organisms or whole genomes.
True
False
If two organism differ in their G+C content by more than 10%, their genome have quite different base sequencing.
True
False
Which of the following is not true for DNA-DNA hybridization?
It measures the percentage of each nucleotide present
It measures the information on nucleotide sequence
DNA homology measures the order of nucleotides and genome composition
If no hybridization occurs, the organisms are unrelated
Small subunit rRNA is ideal for sequencing because..
The structure changes very slowly with time
They can tolerate large mutations
They are the subject of horizontal gene transfer
They are critical organelle that can only be found in certain organisms
