Answer:
When clotting factors in the plasma are activated to form a blood clot, the fluid portion of plasma that remains is known as <u>serum.</u>
Explanation:
The liquid part of blood is known as the plasma. it makes about 90 per cent of the blood and comprises of antibodies and the clotting factors.
If the clotting factors or the fibrinogens are removed from the plasma, then the fluid that remains is termed as serum. The blood serum contains useful proteins like the albumin and antibodies. The serum is the part of the blood that is mostly used for the diagnostic tests.
Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.
