Answer/Explanation:
An important way of selecting for bacteria carrying specific recombinant DNA is to add a resistance gene (such as antibiotic resistance) to your gene of interest. That means that any bacteria that carry your DNA will be resistant to a specific antibiotic (in this case streptomycin). Therefore, you can grow your bacteria on plates with streptomycin, and in theory, the bacteria will be unable to grow if they don't have the resistance gene and your gene of interest.
Here, strain A does not grow on streptomycin plates, but strain B now has 100 colonies. This suggests strain B can grow on streptomycin, meaning it is resistant.
Strain B is therefore the streptomycin resistant master plate strain.
Answer:
this is called asexual reproduction
Explanation:
it is where one parent makes a clone of themselves through budding.
The asnswer is 2DG also known as 2-Deoxy-D-glucose. 2DG is a glucose molecule that has the
2-hydroxyl group replaced by hydrogen, so that it cannot undergo further
glycolysis. As such; it acts to competitively inhibit the production of
glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of
glycolysis).
