00:01
So in this particular question we have an experiment that we have performed and we have certain results.
00:06
So what are the results? the result is such that certain antibiotics are used.
00:12
So what is antibiotics is the first question.
00:15
Now when you say antibiotics, what is antibiotics? now antibiotics is a certain type of medication, right? it is a medicine which has a specific action.
00:26
That is it either inhibits or it destroys okay what does it inhibit or destroy so medicine which inhibits the growth of microorganism written as mo or destroys a microorganism is what is called as antibiotics so this is a kind of medicine which has a inhibitory action on microorganism or or it directly destroys the microorganism but the action of antibiotics is specific to certain microorganism.
00:58
Now in the experiment that we have performed according to the question, we have used antibiotics such as tetracycline written as tc, steptomycin written as sm and chloramfinical written as cp.
01:14
So tetracycline, streptomycin and chloramfinichol are the antibiotics that we have used in this particular experiment.
01:21
And we see that the action of these are present in inhibiting the growth of certain bacteria which are prokaryotes.
01:32
We write prokaryotes as p.
01:34
So these have a broad spectrum activity against prokaryotes, but not against eukaryotes, such as fungi and all.
01:43
Why is this so? first of all, we know that there are two types of cells.
01:48
One is the prokaryotic cell.
01:49
Another one is a ucariotic cell so prokaryotic is represented as p uchariotic is represented as e now the basic difference and the most important difference we obviously know that the prokaryotics does not have the presence of nucleus represented as n here whereas uchariotics have the presence of nucleus represented as n here again so this is a major difference but also when you see the ribosomes represented as r of prokaryotes and ribosomes of eukaryotes is a major difference...
