Genes for the resistance of antibiotics are often located:

• A. on ribosomes
• B. in the cell wall
• C. on plasmids
• D. in the nucleolus

Answer: (C)

Verified step by step guidance

1. Understand that antibiotic resistance genes are genetic elements that provide bacteria the ability to survive exposure to antibiotics.
2. Recall that ribosomes are cellular structures responsible for protein synthesis, not locations for genetic material encoding resistance.
3. Recognize that the cell wall is a structural component of bacteria and does not contain genetic information.
4. Know that the nucleolus is a region within the eukaryotic nucleus involved in ribosome production and is not present in bacteria.
5. Identify plasmids as small, circular, double-stranded DNA molecules separate from chromosomal DNA, which often carry antibiotic resistance genes and can be transferred between bacteria.
