Systematic Bacteriology Quiz
Based on the sequences given, which is the most related to the bacteria X?
Bacteria X: GGC ACG TTA ATT GGC
bacteria A: GGC ATT CCG ATT GGC
bacteria B : GTC ACG TCC AGG CCA
bacteria C: GGC TCG TTA ATT GGC
bacteria D: GGC ACG TTA ATT TTA
In an approach called _______ taxonomy, relatedness is determined by a wide range of phenotypic and genotypic information
Which of the following method can best reveal the evolutionary phylogenetic relationship?
A. 16S rRNA sequencing
C. Biochemical reaction
D. Gram staining
Which of the following is NOT a characteristic of the phylum Proteobacteria?
A. the phylum contains 5 classes
B. they are the largest group of bacteria
C. they are all Gram negative
D. Staphylococcus is in this phylum
What is the common ancestor of letters A, B, C, D and E?
Photosynthetic, nitrogen fixing, similar to chloroplasts. Which phylum belongs to these characteristics?
_______ is an evolutionary tree or a branching diagram or tree showing the “inferred” evolutionary relationship among various biological species or other entities
A. Line graph
E. coli belongs to which class of phylum Proteobacteria?
Microorganisms do not generally reproduce sexually, therefore species are usually defined by phenotypic and genotypic characterisation
Usually Gram-positive, high GC, make antibiotics. These characteristics refer to which phylum?
Members of the phylum ________________, formerly known as the green nonsulphur bacteria, have primarily been associated with extreme habitats such as hot springs, and hypersaline environments where they are known as (filamentous) anoxygenic photothophs
Which bacterial phylum belongs to ‘low G+C Gram positive’ bacteria?
What is the common ancestor of C and D?
Which is the correct order of making phylogenetic tree?
A. sequencing –> alignment –> amplification –> tree construction
B. tree construction –> sequencing –> alignment –> amplification
C. amplification –> sequencing–> alignment –> tree construction
D. amplification –> alignment –> sequencing –> tree construction
Gram-negative, spiral shaped, flagellated. These characteristics belong to which phylum?
