Question 20

An example of a suppressor mutation would be

Question 23

The mechanism for reactive oxygen species to cause mutation is

Discuss the morphology, staining characteristics, growth requirements, or other diagnostic criteria and clinical significance of 4 different bacteria that you studied this semester. While your choices should cover both Gram positives and Gram-negatives as well as rods and cocci, the emphasis should be on the clinical aspects which may include possible treatment.

Pick 3 different subphylla of protozoan parasites and discuss the clinical syndrome associated with a representative genus of each

what is the role of hypothalamus in gender identity?

List two classes/types of antibiotic for each of the following targets: Cell wall Synthesis and Protein Synthesis. Describe how this class of antibiotics specifically work and why this makes them selectively toxic.

Which of the following is correctively matched?

Describe the developmental origin of the adrenal glands. For the steroid hormones cortisol and aldosterone, explain how synthesis of the hormones are regulated in the adult. What would be the consequences of a sudden failure of adrenocortical function and over production of hormones? (500words)

Discuss the Extinction Risks for Coral Reefs as a result of Coral Bleaching.
Coral reef ecosystems around the globe are threatened by human interferences and climate
change. This has led to many scientists conducting studies on global coral reef ecosystems to gain
a better understanding of the cause and effects of coral reef damage.

We will take four opportunities to engage in discussion on the selective topic such as :origins,human impacts, biodiversity, environmental factors and algal diversity . You will identify the significant that associates the topic and overall invertebrates.

Key connections:
Climate change; global warming, symbioses, diversity Important, human impact, and coral reef conservation.

Important Questions:
Can it be reversed? Or can coral habitats be restored?
Examples of resources: Primary literature information.

Explain how left-right asymmetry is established in the mammalian
embryo, including cellular and molecular detail in your answer. What are cilia and what patterning defects might you expect in embryos that fail to form cilia?(500words)

The three forms of open neural tube defect are anencephaly,
craniorachischisis and spina bifida. Explain the embryological origin of
these disorders, with reference to the morphological events that occur
during normal mammalian neural tube closure. In your answer describe
what is known of the causes of these disorders, at the cellular and
molecular level? (500words)

1. A. What is parthenogenesis? How does this seems to occur in birds? What is the main barrier to this happen in mammals? How could parthenogenesis be engineered in mammals?

B. What would be needed to regrow a human limb in the lab to later be transplanted on an amputee?

This is a three part question:

a) What are some major differences between making transgenic mice by microinjection and creating knockout mice by homologous recombination (before the advent of CRISPR/Cas9 technology)?

b) Explain how negative and positive selection work when creating a knockout mouse. Why are both types of selection useful?

c) Why is the creation of knockout mice so much easier when using CRISPR/Cas 9 genome editing?
