AP BIOLOGY

Detailed explanation-1: -DNA transposons can be found in both eukaryotes and prokaryotes. The bacterial transposons belong to the DNA transposons and the Tn family, which are usually the carrier of additional genes for antibiotic resistance.

Detailed explanation-2: -Bacteria can acquire antibiotic resistance genes from other bacteria in several ways. By undergoing a simple mating process called “conjugation, ” bacteria can transfer genetic material, including genes encoding resistance to antibiotics (found on plasmids and transposons) from one bacterium to another.

Detailed explanation-3: -Bacteria and fungi can carry genes for many types of resistance.

Detailed explanation-4: -Plasmids are small DNA circles outside the bacterial chromosome. Several antibiotic resistance genes can be present on the same plasmid.
