Answer:
Explanation:
The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.
The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.
The example of bacteriostatic antibiotic is Tetracycline that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.
The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.
Answer:
S strain
Explanation:
The Avery experiment demonstrated DNA is the genetic material. It expanded upon the findings made by Griffith.
They used Pneumococcus; Smooth strain which was virulent and the Rough which was not.
Cultures of heat killed smooth strain were prepared after which it was treated with DNases ,RNases and Proteinases to remove DNA, RNA, and proteins respectively. It will then be introduced to living Rough strain.
When treated with RNases only the RNA will be destroyed and transformation will take place leading to colonies of S stains being formed.
Only when treated with DNase did the colonies S strain fail to be formed.
