The total length of DNA in the haploid genome is approximately 3 x 109 base pairs. a. Given that the distance between each base pair is 0.34 nm, what is the total length of DNA (in meters) in a diploid human cell? For this is got 2.04 m b. It […]

Question: Suppose You want to add PMA to 15mL of HL-60 cells so that you have a concentration of 5nM. Your stock solution is 1uM. What is the volume of the stock solution you need? Question: The molecular weight of vincristine, a pharmaceutical drug, is 923.04. It is supplied in 1 mg […]

Each individual blastomere of an early-stage embryo is considered to be totipotent. However, there is a “critical mass” requirement for an embryo to develop into a viable offspring. Explain why. Explain how a synchronous and/or uneven cleavage leads to early differentiation into inner cell mass and trophoblast tissue. If you […]

Q. The human circulation flows at the rate of 5 l/min (5 liters/min) at a mean (constant) arterial pressure of 100 mmHg, and at a mean venous pressure of 2 mmHg. Recall that human circulatory system is closed such that flow at any one point is the same. Suppose the […]
