What is meant by internal lane standard and how is it applied in DNA?

The internal lane standard refers to a set of known DNA markers or controls used in molecular Biology techniques, such as gel electrophoresis, to benchmark the size and quantity of DNA fragments within a sample. It helps in assessing the accuracy and reliability of DNA analysis by providing a reference for comparison. In DNA applications, internal lane standards facilitate the identification and quantification of specific DNA sequences, ensuring consistent results across different experiments or samples.
