Question
The model shown here illustrates the ability of rat liver cells to grow in a Petri dish with minimal histidine, an essential nutrient. Which statement correctly describes how the rat liver cells can grow on the media with minimal histidine?
Responses
A The rat liver cells underwent cell division using the histidine from dead and discarded cells in order to grow. The rat liver cells underwent cell division using the histidine from dead and discarded cells in order to grow.
B The rat liver cells were incubated with a chemical that caused mutations that allow the cells to produce their own histidine.The rat liver cells were incubated with a chemical that caused mutations that allow the cells to produce their own histidine.
C The rat liver cells were induced to grow in the absence of histidine by producing their own proteins that do not contain histidine.The rat liver cells were induced to grow in the absence of histidine by producing their own proteins that do not contain histidine.
D The rat liver cells were incubated with a chemical that supplied sufficient histidine and other nutrients that allowed the cells to grow.

The correct statement that describes how the rat liver cells can grow on media with minimal histidine is:
**B. The rat liver cells were incubated with a chemical that caused mutations that allow the cells to produce their own histidine.**
This response suggests that the cells underwent a modification that enabled them to synthesize histidine independently, which is a plausible mechanism for their growth in minimal histidine conditions.
