Fraction - GCSE Biology Definition

In GCSE Biology, a "fraction" refers to a portion or part of a mixture that has been separated based on specific characteristics, like size or density. For example, during a process called "fractionation," a cell's contents can be divided into different fractions, such as proteins, nucleic acids, or other cellular components. This helps scientists study specific parts of cells and understand their functions better. It's like dividing a pizza into slices, where each slice is a fraction of the whole pizza, allowing you to examine or enjoy each piece separately.
