Minute in Biology

In biology, a minute can have several different meanings depending on the context.

1. Minute as a Unit of Time

When used as a unit of time, a minute is equal to 60 seconds. It is often used to measure short durations in biological processes, such as the time taken for a chemical reaction to occur or the duration of specific events in cellular processes.

2. Minute as a Descriptor of Size

In biological contexts, "minute" can also be used as a descriptor of size, typically referring to something very small or tiny. For example, minute structures within cells, such as organelles or cellular components, may be described as "minute" in size.

3. Minute as a Mutation

Additionally, in genetics, a "minute" can refer to a specific type of mutation that affects the rate of development in Drosophila melanogaster (fruit flies). These mutations were first studied by Thomas Hunt Morgan and his colleagues and are characterized by a lengthened developmental time compared to normal flies.
