What is the relationship between Natural Selection and antibiotic resistance? How has Horizontal Gene Transfer (HGT) accelerated the process
Homework Answers
Natural selection is the selection of trait by Nature Whereas antibiotic resistance is the artificial selection of bacteria which has antibiotic resistance in it.
Natural selection can select any trait in any organism where as antibiotic resistance select the ability of a microbial cell to grow in the presence of antibiotics.
Horizontal gene transfer if the mode of transmission of genes from one bacterium to the other, both of which may or may not belong to the same generation. The process of antibiotic resistance have been accelerated by horizontal gene transfer. So gene for antibiotic resistance is present in plasmid and horizontal gene transfer involves transfer of plasmid. It does not results in the transfer of chromosomal genes of microbes. So the plasmid carrying antibiotic resistance is transferred from one bacterium to the other during the process of horizontal gene transfer, increasing the number of bacteria containing this gene.

The following is in regards to Horizontal gene transfer (i.e. transfer of info amongst cells from same generations rather than from parent cell to offspring cell). In terms of rapid development of multiple drug resistance, why is horizontal gene transfer of greater significance than vertical gene transfer? Name and explain two mechanisms of HGT (horizontal gene transmission). Describe two resistance mechanisms that bacteria may use to decrease susceptibility to a particular antibiotic.

How do bacteria that have never been treated by antibiotics acquire genes for antibiotic resistance? (1 pt) These bacteria are naturally resistant to all antibiotics. II.
