How is horizontal gene transfer important in spreading antibiotic resistance? It allows resistant bacteria to share their genes with sensitive bacteria O It breaks down antibiotics O It destroys natural antibiotic-producing organisms O It kills off sensitive bacteria

Which of the following is an example of horizontal genetransfer?a. The transfer of a gene from one strain of E. coli to a differentstrain via conjugationb. The transfer of a gene from one strain of E. coli to a differentstrain via transductionc. The transfer of an antibiotic resistance gene from E. coli toSalmonella typhimurium via transformationd. All of the above are examples of horizontal gene transfer.

Conjugation differs from other means of horizontal gene transfer between bacteria cells because conjugation requires cell division. a bacteriophage virus. physical contact between the bacteria cells by a pili. heat-killed cells to release their DNA. DNA replication.

In Experiment I, you established that beneficial mutations are rare. In Experiment II, you showed that the environment does not affect the probability of a beneficial mutation occurring. Knowing this, why then are mutations responsible for antibiotic resistance in bacteria so common?
