Q1. The functional lac repressor is a homoteramer. Still, the X-ray structure of lac repressor bound to the lac operator sequence centered at +11 reveals that the two half sites that constitute the complete operator sequence with two-fold rotational symmetry are each bound by a monomeric subunit of the repressor. If repressor tetramer uses only two of its subunits to bind to an operator sequence, why is tetramer formation so important to the control of lac operon gene expression?
Q2. The counter current exchange respiratory system of fish, which of the next would not be expected?
1. Blood flows through the gills from anterior to posterior. 2. Water travels over the gills from anterior to posterior. 3. In the back (posterior) portion of the gill, amount of carbon dioxide in the gills is higher than the water. 4. In the front (anterior) portion of the gill, amount of oxygen in the gills is lower than the water.
Diplomonads, such as Giardia contain two haploid nuclei per trophozoite. Thus, During the G1 phase of the cell cycle, there should be a total of how several unreplicated chromosomes per trophozoite, and throughout the G2 phase, how many replicated ch..
At another locus, sepia eyes are inherited as an autosomal (non sex linked) recessive. The presence of the white eye phenotype (x superscript w x superscript w in females, x superscript y in males) masks sepia phenotype, so regardless of the sepia ge..
What is estimated density of firs in the forest. Why then is the gene called Dorsal, and not, for instance, Ventral.
A middle-aged man comes in since he has noticed multiple small, blood-red, raised lesions over his anterior chest and abdomen for past numerous months. They are not painful and he has not known about any bleeding or bruising. He is concerned this mig..
If a transferrin receptor has a cross-sectional area of 50 Angstroms X 100 angstroms (5x10nm), and how many receptors could be accomodated in a 100nm clathrin-coated vesicle assume that only 50% of surface area can be occupied by proteins.
You now grow Daphnia and Bosmina together. Suppose they remain limited by phytoplankton. What genetic basis of erminette pattern is suggested? How would you test your hypothesis.
What phenotypes will you suppose among the 1024 offspring, and how many of each phenotype would you expect.Suppose that a cross is made between a fly with normal wings.
How various kilograms of diatoms are needed to build 1 metric ton (1000kg) of blue whale. Give details how filter feeding by blue whales enables them to grow so large.
Some wines are marketed as "sparkling" wines. Sparkling wines are considered so because of a dissolved gas that makes them fizzy. Concern what you know about the procedure of respiration to explain the type and origin of this gas.
You get a soil sample and run an enrichment culture on it. You give the organisms in the culture with all of the ingredients required for growth except for nitrogen. What result do you expect to have at the end of the experiment.
What type of electrode would they need to use (express material and design)? Provide a simplified schematic (circuit model of the electrode) described in the notes. Also discuss at least two benefits of an exoskeleton as well as how arthropod grows ..
The measurements to be comparable in both preparations. Illustrate one experiment you could perform to demonstrate such lack of equivalence of the two cells in the zygote. Noticeably state the expected outcome of your experiment in the reply you prov..
