Answer:
Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes. The correct sequence is 1, 3, 2; based on the options given.
Explanation:
The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1. Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3. Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2. Incubate at 72°C to promote the extension of the DNA strands, actually extending them.
Answer:
This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise. So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around full and new moon.
Explanation:
Six distinct antibody subtypes can be produced in response to the antigen.
It is assumed that a certain antigen has six distinct antigenic determination sites.
To find out how many various types of antibodies this antigen can trigger production of, read on.
A molecule, chemical structure, foreign particle, pollen grain, or any other substance that can attach to a particular antibody or T-cell receptor is referred to as an antigen.
An epitope is an antigenic determinant, which is the component of an antigen that the immune system recognizes.
An antibody is a large, Y-shaped protein that the immune system employs to recognize and destroy foreign substances like dangerous germs and viruses.
