A skin cell from a human female undergoes mitosis. For an unknown reason, the centromere of one of the two number 4 chromosomes fails to divide. Describe the resultant chromosome number of the two daughter cells. Indicate the genetic make-up each cell. Suppose this happened to a single cell in reproductive tissue undergoing meiosis II (the cell went through Meiosis I normally). What would be the chromosome number of the resulting cells from this cell? You need to indicate the number of cells that result as well from the complete process of meiosis. A diagram is will help here. If instead of a problem with Meiosis II, the problem was with homologous chromosomes not separating in Meiosis I, what would the complement of chromosomes be for each of the resultant oocytes produced? For all scenarios assume that the cells go finish the mitosis and meiosis even if not viable due to an abnormal chromosome count.
Salmonella enterica is closely related to Escherichia coli. It can be infected with the F plasmid, which can integrate into the chromosome to produce Hfr strains.
Discuss what you would require to know to answer the following question: of all proteins that exist on earth at this time, what fraction of them have a known structure?
What can be said about a human whose cells contain Barr Bodies.
Briefly discuss the disease or deficiency describing typical symptoms, treatment, and prognosis.
Suppose that you have engineered a set of genes, each encoiding a protein that altered signal sequence. If the genes were expressed in a cell.
Epithelial tissue covers all inner and outer: A. surfaces B. spaces C. ears D. nervous systems D. any of the above could be equally valid.
In context if chemical evolution, DNA's structure is interesting because it suggests a possible copying mechanism. What about DNA's facilitates copying?
Discuss and briefly explain the three processes that would explain how pseudomonas could transfer its genetic resistance to Enterobacter and Klebsiella.
At one end there is an aldehyde group (call this carbon atom 1). All the other carbon atoms carry OH groups -- they are, then, alcohol functional groups, 5 of them.
For each of the following hormones- epinephrine, rennin, angiotensin II, aldosterone, ADH, and atrial natriuretic hormone- state where each is produced, what stimulus causes increased hormone production, and the hormone's effect on the circulatory..
What are effects of surface area on rate of diffusion?
With these anatomical features in mind, do research to find an angiosperm species that has structural modifications to leaves, stems, roots, or flowers that result in adaptive functions. For example, a California Barrel Cactus has spines in place ..
