Question

question 2 of 10
which of the following correctly describes bacterial transformation?
a. a gene in a bacteriums plasmid is moved to the bacteriums chromosome.
b. extracellular dna is taken up by a bacterial cell.
c. the genome of one bacterium is replaced by the genome of another bacterium.
d. a small strand of dna is removed from a bacterial cell.

Explanation:

Bacterial transformation is defined as the process where a bacterial cell takes up extracellular DNA. Option A describes a gene transfer within the bacterial cell (not transformation). Option C is incorrect as it's not about replacing the whole genome. Option D is about removing DNA (opposite of transformation which is uptake). B matches the definition of bacterial transformation.

Answer:

B. Extracellular DNA is taken up by a bacterial cell.
