What is arabinose in bacterial transformation?

Sourav PanDecember 7, 2024

Answered

Arabinose is a sugar that acts as an inducer in bacterial transformation experiments where plasmids contain an ara operon or similar regulatory systems. In the presence of arabinose, specific regulatory proteins activate gene expression controlled by the operon. This allows researchers to switch on or off the expression of a target gene, such as one encoding a fluorescent protein or an enzyme, enabling precise control over experimental outcomes.
