What is one of the main purposes of DNA sequencing?

Determining the base sequence of a DNA segment is one of the primary purposes of DNA sequencing. This process allows scientists and researchers to identify the exact order of nucleotides (adenine, thymine, cytosine, and guanine) within a DNA molecule. This base sequence information is crucial for understanding genetic information, the function of genes, and how variations in the sequence can lead to differences in traits or susceptibility to diseases.

By analyzing the base sequence, researchers can also make comparisons between different organisms, identify genetic mutations, and study evolutionary relationships. The insights gained from DNA sequencing have applications in various fields, including medicine, genetic engineering, and forensic science, making it an essential tool in modern biology.
