1. Please describe the main features of the DNA structure. (10 points) Key features: (1) Double helical structure (4’) (2) Two strands are held together in an antiparallel orientation (3’) by base paring (1’)

Describing the following terms (4 points each) 1. Cre recombinase 2. CSSR recombination 3. Mating-type switching 4. Mismatch repair 5. Polymerase switching 6. 30-nm fiber 7. Core histones

Your answer should describe what each item is and how it functions in the cell. Diagrams, structure and sequence information should be included in your answer, as necessary. 1. Yeast artificial chromosome 2. RNA interference 3. Proteomics

PART I: DESCRIPTION (2 points each) Your answer should describe what each item is and how it functions in the cell. Diagrams, structure and sequence information should be included in your answer, as necessary

compromised body in low numbers), organisms that are normally nonpathogenic can cause infection. The infectious dose will vary with the organism and the health of those infected. For example, Shigella flexneri requires the ingestion of only a few hundred organisms to cause intestinal disease. Salmonella typhi requires

What Do You Know about Your Protein? In order to make informed choices among the bewildering range of available transfer and detection methods, it is best to have as clear an idea as possible of your own particular requirements

Molecular biologists routinely use restriction enzymes as key reagents for a variety of applications including genomic mapping, restriction fragment length polymorphism (RFLP) analysis, DNA sequencing, and a host of recombinant DNA methodologies. Few

Recombinant gene expression in eukaryotic systems is often the only viable route to the large-scale production of authentic, post￾translationally modified proteins. It is becoming increasingly easy to find a suitable system to overexpress virtually any gene product

How Important Is Cost? Reagents obviously figure into the cost of a procedure, but the labor required to produce and apply the reagents of purification should also be considered. How Important Is Reproducibility (Robustness) of the Procedure?
