Would you describe the AC/Str-s as competent? Why or Why not?

Molecular Cell Biology

List the two changes affecting chromosomes that make chromosome segregation during meiosis one different from chromosome segregation during mitosis (do not mention microtubules in your answer).

1. A protist is any organism that is not a plant, an animal, a fungus, or a(an)

   	A.	prokaryote
   	B.	eukaryote
   	C.	eubacterium
   	D.	archaebacterium

A person's mouth is sampled with a sterile, moistened swab and a plate of tryptic soy agar is inocluated with the swab. After the appropriate time of incubation is allowed, no growth appears on the plate. Which of the following is the most reasonable explanation for this result?

a. the person's mouth was sterile

b. plate should have been incubated under anaerobic conditions

c. the tryptic soy agar lacked some nutrients required the mouth microbes

d. tryptic soy agar contained a compound that inhibited the growth of the mouth microbes

3. Where in the cell does TRANSCRIPTION occur?

A. nucleus B. mitochondria C. chloroplast D. All of the above

9. mRNAs usually have a start translation site of AUG. true or false?

16. Which type of RNA makes up the spliceosome?

A. rRNA B. snRNA C. tRNA D. snRNPs E. siRNAs

17. Which type of PROTEINS help make up the spliceosome?

A. rRNA B. snRNA C. tRNA D. snRNPs E. siRNAs

25. Introns have conserved sequences that help to orient the spliceosome into a lariat structure. Which nucleotide represents the conserved branch point?

A. A B. U C. C D. G

26. What is the ultimate effect of siRNAs and miRNAs?

A. The mRNAs that are complementary to the siRNA or miRNAs are translated at a HIGHER rate.

B. The mRNAs that are complementary to the siRNA or miRNAs are translated at a LOWER rate.

Describe what is meant by the terms ‘pan genome’ and ‘core genome.’ What sorts of genes do you expect to be present in the core genome? What sorts of genes are found in the pan genome but outside the core genome? What processes of genetic exchange give rise to the great diversity of genome sequences in the various strains of a given species?

1. Discuss the role of these pathways in cancer progression: hypoxia, angiogenesis, EMT and cell cycle regulation.

2. What pathways are each of these genes evaluating? Keep in mind the answers to question 1 above and describe the relationship between changes in these genes and cancer progression.

What are the pros and cons of using monoclonal antibodies vs polyclonal antibodies?

If you had a protein expressed at low levels that you were trying to isolate, which would you use?

1) Distinguish between the structures and functions of the smooth and rough endoplasmic reticulum.

2) What types of cells might have lots of smooth ER? (HINT: which organ in your body detoxifies drugs?)

3) What is a lysosome? Compare to an organ in your body. What two functions does it do in a cell?

1. What are the experimental limitations of this binding assay? List ways to fix them

List the fruit peels other than orange having esterase enzyme and compare them based on the quantity of the enzyme.

Describe the different levels at which metabolism can be regulated (transcriptional, translational, post translational).
