Question

Bacteria may become resistant to overused antibiotics. Selective environmental pressures may allow the resistant bacteria to thrive. How do these bacteria replicate and transfer the resistance?

engulfing cellular DNA by neighboring cells

replicating cells by cleavage

gene transfer

transferring genetic information by meiosis

Answer 1

When bacteria become resistant to overused antibiotics it means that is not longer inhibited by the antibiotic at clinically achievable levels. One way how these bacteria replicate and transfer the resistance is by engulfing cellular DNA by neighboring cells.Bacteria can take up naked DNA encoding for resistance native to similar species and incorporate it into their genome
