Summary Introduction
Introduction:
Elek’s test is an immunodiffusion test which helps to detect the toxigenecity of diphtheria. A filter paper strip containing diphtheria antitoxin is placed on a solid culture medium. Then, bacteria are streaked through the right angle to the filter paper. If the bacteria are toxigenic, a line of antigen and antibody precipitate will form.

Explain the impact William B. Travis has made.
If PCR was performed on the fragment of DNA shown below using "5'-TAGG-3" and "3'-TCTA-5'" as the primers, how many base pairs long would the PCR product be? To help with this, remember the antiparallel structure of DNA and that primers are complementary and antiparallel to the target sequence that they bind to. Hint: Check out the 5' and 3' labels....they are important!

Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.
