Agarose gel electrophoresis is a method used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules, such as DNA, RNA, or proteins, in an agarose matrix.

C printf Function: Format Specifiers Explained

The printf function in C is used to display formatted output to the standard output (usually the console). It allows programmers to control how data is presented by using **format specifiers**.
