What is the small loop of DNA that can get transferred from one bacterium to another bacterium called?

Answer 1

Plasmids are commonly found in bacteria as small circular, double standed DNA molecule.

A plasmid is a tiny DNA molecule that can replicate on its own within a cell and is physically distinct from chromosomal DNA.

The only additional genes that plasmids typically contain are those that might be helpful to the organism in specific circumstances. Plasmids are typically very small.

Transformation, transduction, and conjugation are the three ways that plasmids can spread from one bacterium to another.

Plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state. Plasmids often carry genes that may benefit the survival of the organism, e.g., antibiotic resistance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
