If Angiotensin-converting enzyme 2 is present in lung cells at 1000 copies/cell, how many cells do you need to grow in order to provide 100 fmol for the identification of novel phosphorylation sites in Angiotensin-converting enzyme 2?
Homework Answers
One mole of any substance contains 6.023 X 1023 copies of it. So, 1 M of Angiotensin-converting enzyme 2 has 6.023 X 1023 copies of it. 100 fmol = 10-13M, which has 6.023 X 1010 copies of it. It was given that,the lung cells have 1000 copies of this enzyme per cell. So, to get 6.023 X 1010 copies of enzyme, the number of cells required is 6.023 X 1010 / 1000 = 6.023 X 107 cells.

5.To gain entry, spikes of the SARS-CoV-2 bind to
angiotensin-converting enzyme 2 (ACE2) found in epithelial cells
especially of the respiratory and oral passageways. As such, these
cells are susceptible to infection by SARS-CoV-2. ACE2 is a protein
consisting of multiple alpha-helices that is embedded in, and
spans, the membrane. What is this type of protein called, and what
structure do the alpha helices represent?

• 4. How many copies of the primers do you add to the PCR? You add 3 pl. of a 5 M solution of each primer, If you had 100 copies of the template DNA would there be enough primers to support 30 cycles of PCR? Remember the amount of template doubles (in theory) with each cycle. After 1 cycle there will be 2xthe starting amount, after 2 cycles 4 x the starting amount.

(b) How many positive integers between 1000 and 4999, inclusive: 1. have no repeated digit? 2. have at least one repeated digit? 3. have at most two repeated digits? Note that by 'one repeated digit' we mean that there is a digit that appears at least twice (eg, 1123 has one repeated digit). Similarly, by two repeated digits we mean a digit that appears at least...
