Question

Antibiotic resistance occurs when an antibiotic has lost its ability to effectively control bacterial growth. In other words, the bacteria are “resistant” and continue to multiply in the presence of therapeutic levels of antibiotic. Which statement best explains this natural phenomenon in terms of Darwin’s theory of natural selection. A. The antibiotics caused certain groups of bacteria to suddenly start producing enzymes that destroyed the antibiotic before it could harm the bacteria. B. When an antibiotic is used, bacteria that have a natural variation for resistance to the antibiotic have a greater chance of survival. C. Although susceptible bacteria are killed or inhibited by an antibiotic, any offspring they produced before they died will be resistant to the antibiotic. D. The need to adapt or die caused some bacteria to become resistant to the antibiotic. This acquired resistance was passed into the future bacteria populations making them resistant.

Step 1

Antibiotic resistance occurs when bacteria evolve to survive exposure to antibiotics that would normally kill them or inhibit their growth. This means that the bacteria can continue to multiply even in the presence of the antibiotic. Show more…

00:01 In this question here hf for e.

00:06 Coli cell.

00:07 So hfr e.

00:08 Coli cell.

00:09 So it serves as a donor for gene transfer.

00:14 So e.

00:14 Coli cell, it acts as a donor for the gene transfer.

00:18 We have to assume that.

00:19 So the particular short lines, they indicate.

00:23 So here, short lines are they do these short lines.

00:27 So these short lines, they indicate the paid genes.

00:32 2 5 are located that is out of 4 ,500 total genes where 1 to 5 genes that means 1 ,3, 4 ,5 genes where they are located on the genes of e.

00:47 Coli chromosomes.

00:49 So for each gene transfer mechanism, each and every gene transfer mechanism, they are listed below here, 1, 2, 3, 4, 5.

01:02 Genes these genes are transferred these genes are transferred so we have to state we have to explain or we have to tell which genes are more likely to be transferred in the following cases okay so but the first one that conjugation so during conjugation which of the genes has been transferred so during the conjugation phase the sequence which having the f factor, so the sequence which having the f factor will be, f factor will be transferred.

01:46 So this f factor, the sequence where the f factor it is there, know, that it will be transferred.

01:53 That is the genes between 1 to 5...
