The formula to calculate the bacteria transformation efficiency is:
\[ x = \frac{y}{z} \times 100 \]
Where:
Transformation efficiency is defined as the efficiency by which biological cells can take up extracellular DNA and express genes encoded by it.
Transformation efficiency can be used to tell us how well the transformants of a cell can absorb DNA from outside the cell and express the genes of the DNA that was absorbed in its own makeup.
A transformation efficiency depends on the competence of the cells that are absorbing the extracellular DNA.
Let's assume the following values:
Step 1: Calculate the transformation efficiency:
\[ x = \frac{200}{50} \times 100 = 400 \text{ transformants/ng of DNA} \]
