Question

Plasmids are small, double-stranded DNA molecules that can exist independently of the chromosome. They are often responsible for conferring which of the following survival advantages to bacteria?
Options
A Flagellar motility
B Ability to perform photosynthesis
C Resistance to antibiotics
Correct Answer
D Formation of endospores
Correct Answer

Detailed Explanation

Plasmids (especially R-plasmids) often carry genes conferring survival advantages such as antibiotic resistance, toxin production (virulence plasmids), or metabolic capabilities. They are crucial to the spread of antibiotic resistance.

Hint

Think about how bacteria acquire new traits that help them survive in challenging environments, like medical settings.
