What does transformation mean in DNA?
Plasmid or vector transformation is the process by which exogenous DNA is transferred into the host cell. Transformation usually implies uptake of DNA into bacterial, yeast or plant cells, while transfection is a term usually reserved for mammalian cells.

After transformation, bacteria are selected on antibiotic plates. Bacteria with a plasmid are antibiotic-resistant, and each one will form a colony.
What is the transforming principle in biology?
The transforming principle was an early name for DNA. … Transformation occurs when one bacterium (you know, those microscopic, single-celled creatures) picks up free-floating DNA and incorporates it into its own genome. The idea of the transforming principle was discovered during an experiment by Frederick Griffith.
What is transformation in biology for kids?

What is transformation in biology quizlet?
