Microbial Organisms
Not what you're looking for?
I) Compare and contrast eukaryotic and prokaryotic microbial chromosomes.
ii) What is transcription and translation?
iii) Describe the appearance and function of plasmids.
iv) Compare methods of categorizing organisms. Are any of them better than the others or are they just different ways at looking at the same thing?
v) Give 2 examples of diseases caused by members of the anaerobic, Gram (-), straight, curved, and helical rods group.
vi) Case Study #1: Mr. B., a healthy 30-year old electrician, suffered third-degree burns over 40% of his body in an electrical accident. After 3 week of intensive supportive care in a burn unit, he suddenly became anxious and confused. His temperature fell to 35.5oC and his blood pressure fell to 70/30mm Hg, and his total peripheral white blood cell count, which had been elevated, fell to 1900/mm3. If you were to take blood cultures, what organism would you commonly find?

Solution Summary
This solution contains detailed information on the similarities and differences between eukaryotic and prokaryotic organisms. It describes transcription and translation, as well as the appearance and function of plasmids. It discusses methods of categorizing organisms and the pros and cons of each of those methods. Examples of Gram negative bacteria that belong to the straight, curved, and helical rod groups are given.
A case study is presented describing a person that has suffered burns and the bacteria that would most likely be found in such a victim.
Solution Preview
Eukaryotic organisms have multiple, linear chromosomes with histones, while prokaryotes have a single, circular chromosome that lacks histone and DNA is contained in both of these.
Transcritption involves the synthesis of mRNA from a DNA template. The mRNA that was synthesized during transcription is used by ribosomes to synthesize proteins.
Plasmids are small, circular often double-stranded DNA molecules. They are considered transferable genetic elements that can replicate independently of the genome.
Organisms have been classified by using phenetics, phylogenetics, and cladistics. Phenetics relies on the appearance of organisms ...

Identifying Variables in Science Experiments, Part 2
Using sample experiments, test yourself to see if you can identify independent, dependent, and controlled variables. Identifying variables is key in understanding and developing experiments. The questions are biology related, but this can be applied to any area of science.
