Give me short answers ( but perfect) for both questions.100-150 words each....
1) Given a choice of the types of genetic mutations discussed in class, which point and chromosomal mutations would be the least likely to cause problems for the eukaryotic organism? Explain your choice.
2) Explain in terms of cellular respiration why we need oxygen and why we exhale carbon dioxide. Is there an alternative to using oxygen? What is the alternative and is it viable option for multi-cellular aerobic organisms to survive long-term in an oxygen deficient environment?
In the evolution of land plants we see several major trends. Describe how the evolution of seeds decreases a plant's dependency upon water.
I have been asked to make a labelled drawing of a plant-likeprotist (using the Euglena as the example), which I have done
A geneticist makes a cross between two homozygous strains of maize with three different mutations. For symbols, you can use a capital to indicate the dominant allele.
Draw a negative feedback loop showing how sympathetic and parasympathetic nerves are affected in someone experiencing a fall in blood pressure (the initial stimulus). Keep in mind that the sensor detects the fall in blood pressure.
What is the role of these proteins in phage integration and immunity? What regions of a phage genome do each of these protein bind/interact?
Design an experiment to detect the presence and number of Acetobacter in wine. Why would you want to perform such test?
If the albino phenotype occurs in 1/10,000 individuals in a population at equilibrium and albinism is caused by an autosomal recessive allele, a, calculate the frequency of mating between heterozygotes.
Calculate these values for the succeeding generation. If the lethal allele arises by mutation at a rate of 10-6 per gamete, what will be its frequency at equilibrium?
A 10ml suspension of cr51 labelled red blood cells containing 3 x 108 cpm total radioactivity was injected into a subject, after 10minutes a small blood sample was taken ,found to contain 5x104 cpm, calculate the total blood volume the individual?
Describe an experiment that would provide this answer, note the possible outcomes of the experiment, and explain the meaning or each possible outcomes.
write about targets for anti-inflammatory drugs. Currently, most drugs either inhibit the synthesis of prostaglandins/leukotrienes (cyclo-oxygenase inhibitors) or they inhibit transcription of genes encoding inflammatory cytokines (such as IL-1, T..
Your friend is trying to generate an in vitro system for studying the formation of COPII vesicles. He finds that to get well-organized vesicle budding from artificial membranes, he needs to add the coat proteins, the Sar1 GTP-binding protein.
