10 Questions
Which method is commonly used to discover many types of bacteria that cannot be grown in a lab?
Metagenomic analysis with environmental DNA
Why is the Biological Species Concept not applicable for defining bacterial species?
Bacteria are asexual and do not reproduce
Which molecule is commonly used to determine the phylogenetic relationships among bacterial species?
16srRNA
Why is the Geological Species Concept more effective for bacterial species compared to other organisms?
Bacterial 16srRNA has a slow mutation rate
Why is the 16ssrRNA only accurate for long periods and not short time spans?
It has a very low mutation rate
Why is the Biological Species Concept not applicable for defining bacterial species?
Bacteria cannot interbreed and produce viable offspring
Why is the Geological Species Concept more effective for bacterial species compared to other organisms?
Bacteria have a slower mutation rate than other organisms
Which method is commonly used to discover many types of bacteria that cannot be grown in a lab?
Metagenomic analysis
Why is the 16ssrRNA only accurate for long periods and not short time spans?
16ssrRNA is only accurate for long time spans
Why are Physiology and Phylogeny not always linked in bacteria?
Bacteria have horizontal gene transfer
Test your knowledge on bacterial evolution and the factors that influence it. Explore topics such as metagenomic analysis, horizontal gene transfer, the relationship between physiology and phylogeny in bacteria, and the role of bacteria in the development of eukaryotic organelles. Plus, learn about the biological species concept and how it defines species based on their ability to interbreed and produce viable offspring.
