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

To calculate the mutation rate, divide the number of mutations by the number of cells per culture.

## How to Calculate Mutation Rate?

The following example problems outline how to calculate Mutation Rate.

Example Problem #1:

1. First, determine the number of mutations.
• The number of mutations is given as: 100.
2. Next, determine the number of cells per culture.
• The number of cells per culture is provided as: 6,000.
3. 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
