Answer:
Option C
Explanation:
DNA fragments have negative charge and they move towards the positively charged electrode in gel electrophoresis.
There is no difference in the charge carried by the DNA fragments as they all have the equal amount of charge on them.
The difference in speed of large and small molecules of DNA is due to their sizes.
Large DNA molecules do not pass easily through the pores of the gel while the smaller molecules do not face any such hindrance and are easily passed through the gel . Therefore small DNA molecules move faster.
F plasmid has the largest size and hence it will move slowly.
Option C is correct
As the plasma cells begin secreting antibody, the antibody titer begins to rise. Eventually , the primary response will make an immune memory of the antigen.
IgM is not the first class of antibody which appear on the surface of developing B cell. It is the major class which secreted into the blood in the blood int he early stages of primary antibody response, which expose to antigen. Primary antibodies occur during the first encounter with virus.
All adaptive immune responses develop in steps, which consisting antigen recognition, activation of specific lymphocytes to proliferate , with the memory cells being the long live survivor.
