Question: Consider the first copy of an allele for insecticide resistance that arises by mutation in a population of insects exposed to an insecticide.
a) Is this mutation an adaptation?
b) If, after some generations, we find that most of the population is resistant, is the resistance an adaptation?
c) If we discover genetic variation for insecticide resistance in a population that has had no experience of insecticides, is the variation an adaptation?
d) If an insect population is polymorphic for two alleles, each of which confers resistance against one of two pesticides that are alternately applied, is the variation an adaptation?
e)Or is each of the two resistance traits an adaptation?
Question: What is the different between Southern blotting and Western blotting?
Most hormones have a basal level of secretion that can increase or decrease based on some condition of change that is detected by endocrine receptor.
For in case, it is well established that in presynaptic neurons, the elevation of cytosolic calcium triggers the fusion of exocytotic vesicles that contain neurotransmitters to the plasma membrane.
Draw the synaptic configuration of homologous pairs of chromosomes when one member is normal and the other member has sustained a duplication within the chromosome
Determine what is known mechanistically about how dosage compensation occurs in mammals/humans? what gene is involved with the process?
Early in development, most human cells turn off expression of essential component of telomerase, enzyme responsible for addition of telomere repeat sequences to ends of chromosomes.
Atherosclerosis is the progressive disease of blood vessels that is responsible for millions of death each year. Explain disease process, noting the involvement of specific cell/tissue types and molecules.
Food resources are rarely shared uniformly in the environment. Most vary seasonally or have a patchy distribution and can become locally depleted.
It was discovered that the replication of the ends of chromosomes was a problem due to the structure of DNA and the properties of enzymes used in the replication process.
