Enter the number of mutations and the number of cells per culture into the Mutation Rate Calculator. The calculator will evaluate the Mutation Rate.

## Mutation Rate Formula

The following two example problems outline the steps and information needed to calculate the Mutation Rate.

**MR = m/N**

- Where MR is the Mutation Rate (mutations per cell)
- m is the number of mutations
- N is the number of cells per culture

## How to Calculate Mutation Rate?

The following example problems outline how to calculate Mutation Rate.

Example Problem #1:

- First, determine the number of mutations.
- The number of mutations is given as: 100.

- Next, determine the number of cells per culture.
- The number of cells per culture is provided as: 6,000.

- Finally, calculate the Mutation Rate using the equation above:

MR = m/N

The values provided above are inserted into the equation below and computed.

MR = 100/6,000 = .0166 (mutations per cell)

Example Problem #2:** **

For this problem, the variables required are provided below:

number of mutations = 500

number of cells per culture = 1,500

Test your knowledge using the equation and check your answer with the calculator..

MR = m/N** = ?**
