What is it about amino acids that give proteins the ability to be such talented molecules and allow them to form macromolecules as diverse as antibodies, enzymes and muscle fibers?

Biomolecules Homework Part 2: There are four categories of biomolecules that can be described as macromolecular building blocks of life: Lipids, Carbohydrates, Proteins, and Nucleic Acids. Question #1 Make a chart that summarizes the following: What are the Monomers and Polymers associated with each category. For each category, include in the chart primary biological functions […]

Narrate the two ancestors’ tales. Explain what it means to you. In what sense do we object to the distinction between ‘higher (advanced) animals’ and ‘lower (primitive) animals’?

The concept of the “ladder of life” or Scalia natural fail Some of your paper can concisely narrate the two ancestors’ tales. However, you should also explain what it means to you. In what sense do we object to the distinction between ‘higher (advanced) animals’ and ‘lower (primitive) animals’? How does the concept of the […]

Using the OCD value from part A, determine the number of colonies that would be expected to grow on a plate that is inoculated with 0.1 mL volume of 10-9 dilution from this same stock of bacteria.

Topic: Serial dilution quiz You have an original cell density of 2.10 x 107 CFU/mL. What is this number in its non-scientific notation or “regular” format? If you’ve taken 500 ul of a bacterial culture and added 500 ul of DI water, you have achieved what dilution (i.e. what is the dilution factor)? Group of […]

Bacterial Culture for Plasmid Amplification Execute the beginning of a bacterial culture Demonstrate the ability to make and run electrophoresis gels. Demonstrate an understanding of electrophoresis and running different percentage gels.

How would you describe the bacterium’s susceptibility to each antibiotic? Choose if each are sensitive, intermediate, or resistant.

Bacterium A specific bacterium was used in testing antibiotic effectiveness. The zone of inhibition measured 14 mm for each antibiotic. How would you describe the bacterium’s susceptibility to each antibiotic? Choose if each are sensitive, intermediate, or resistant. Ampicillin: Chloramphenicol: Erythromycin: Gentamicin: Streptomycin:

Discuss the structure of the membrane protein involved, the interaction of the membrane protein with the ion or sugar it transports, and the speed and selectivity of the process in each case.

Short Essay: “Bridges & Ferry Boats” Ion Channels, Carrier Proteins, and Facilitated Diffusion (25 pts) In cell biology, comparisons can help us understand mechanism. To highlight the differences between membrane channels and transport carrier proteins, it’s been said that channels are like bridges, but carrier proteins are like ferry boats. In your essay, explore this […]
