What is a distinctive feature of the chondrichthyans? What is the difference between glomericoza and mycorrhiza? What is the difference between a twister and a tornado? What is the difference between ethanol and methanol? What is the key difference between a scientific and non scientific questio...
A key feature of the Watson–Crick model was the two strands, each a linear polymer of nucleotides. This model later led to revelations about how the composition and order of the nitrogenous bases of the nucleotides could encode information that was both heritable and had ...
What is the key feature of the CRISPR enzyme that allows it to change a specific DNA sequence? (a) What is recombinant DNA technology (DNA cloning)? (b) Give an example of its use. When does RNA splicing take place? Why is it important?
Regarding bacterial pathogens, this adaptation is an important feature for survival and proliferation during colonization in different host anatomical niches that may represent distinct microenvironments. Escherichia coli is one of the best known and most studied free-living organisms. Pathogenic E. coli ...
