DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. This is a specialized skill that requires advanced knowledge of biology, chemistry, and bioinformatics. Various methods of DNA sequencing are available, including Sanger sequencing, Illumina sequencing, and nanopore sequencing, each with their own advantages and limitations. DNA sequencing is important in understanding genetic diseases, identifying potential drug targets, and studying evolution and biodiversity.
