The boss in your laboratory has just heard of a proposal by another laboratory that genes for eye color and the length of body bristles may be linked in Drosophila. Your lab has numerous pure-breeding stocks of Drosophila that could be used to verify or refute genetic linkage. In Drosophila, red eyes (c +) are dominant to brown eyes (c), and long bristles (d +) are dominant to short bristles (d). Your lab boss asks you to design an experiment to test the genetic linkage of eye color and bristle-length genes, and to begin by crossing a pure-breeding line homozygous for red eyes and short bristles to a pure-breeding line that has brown eyes and long bristles.
Part 1)
List and describe at least three cellular features of bacteria that could be targeted to inhibit or kill bacterial pathogen. Which is a significant flaw in this experimental set-up.
Assume y ou are studying a gene, and its effects on skin cells. You want to find out if the protein made encoded by this gene binds to DNA in a particular place
Water is most dense and therefore heavier at 4 degrees Centigrade. At zero degrees Centigrade ice forms and can float on liquid water. Assume ice were most dense at zero degrees Centigrade. Select the best explanation of what would happen in aquatic ..
Recognizes true statements of cholesterol and its fluidity. Cholesterol increases membrane fluidity that otherwise contains mainly long chain saturated fatty acids.
Describe oxidative and non-oxidative branches of the pentose phosphate pathway and distinguish between these branches in terms of their roles in producing NADPH for biosynthesis reactions or 5-carbon sugar for mucleic acid synthesis.
The "Primordial soup" includes the mixture of elements and gases which are thought to have started life on the Earth. Speculate on how, over the course of evolution, these complex molecules would eventually form the complex life forms such as human..
Explain why only certain cell types are permissive for transcription of HIV proviral DNA. What cellular factors are involved and why?
Consider a transmembrane protein complex that forms a hydrophilic pore across the plasma membrane of a eukaryotic cell. The pore is made of five similar protein subunits, each of which contributes a membrane-spanning alpha-helix to form the pore.
Does this indicate that our original estimate of 350 individuals was too low or too high? Explain your answer in terms of the principles that underlie mark recapture method.
The global community is plagued by increasing incidence of lung cancer, colorectal cancer, breast and pancreatic cancers, prostate cancer, non Hodgkin lymphoma, liver, ovarian and esophageal cancers.
Cartenoids are frequently found in foods that are considered to have antioxident properties in human nutrition. What related function do they have in plants.
If I had a biosphere of plants and animals and air and I radio labelled the carbon in co2, what path will that carbon take through the biosphere, where does carbon go.
