The human and chimpanzee genomes are 98% identical:
a. How many nucleotide positions of the human genome differ from the corresponding positions of the chimp genome? Assume that the human genome is 3200 Mb.
b. If the coding fraction (that in exons) of the human genome is 1.5% of the total and there are 21,000 protein-coding genes (assumed to be equally long), how many nt differentiate that exonic fraction?
I placed some diastase powder in some starch solution in a test- tube. By taking samples from the tube and testing them with iodine,
A 55-year old woman presents with symmetric stiffness and swelling of the proximal interphalangeal joints of the hands and of the metacarpopharyngeal joints, as well as fatigue, malaise, and myalgia. Symptoms are worse in the morning or after exte..
Determine the events that mark the starting and the end of the first interphase period? What happens within the cell in this period?
Compare changes in carbon cycle to that of the nitrogen cycle on human health. Create a conceptual graphical model for how changing the carbon cycle is likely to impact human health.
Explain what occurs during the Krebs (citric acid) cycle andelectron transport chain by describing the following.
A signalling pathway in the cell is turned on by phosphorylation, leading to reduces in cell division. Determine the effect of a mutation that results in the overexpression of an oncogene coding
Two genes located on separate autosomes determine flower color and shape. The gene for flower color exhibits incomplete dominance, where the color can be red.
Explain how penetrance and expressivity can affect the expression of an allele and how epigenetic phenomena affect the observed pattern of inheritance.
Explain the composition of the genetic material in bacteria, in archaea and in eukaryotic cells. Distinguish between the structure and function of the genetic material as chromotin and as chromosomes.
Reactive oxygen species are unstable, or reactive, compounds that result from partial reduction of oxygen. Reactive oxygen species can cause damage to molecules, including membrane lipids and nucleic acids.
Suppose a population evolving by genetic drift in which the frequency of allele K is 0.65. What is the probability that at some point in the future allele K will drift to a frequency of 1?
A microbiologist inoculates a growth medium with 200 bacterial cells/ml. If the generation time of the species is 1.5 hours. How many generations will it take for the culture to contain more than 6,000 cells/ml? How long, in hours, will it be befo..
