What are examples of DNA technologies?

Examples of DNA technologies include polymerase chain reaction (PCR), which amplifies specific DNA sequences for analysis; CRISPR-Cas9, a gene-editing tool that allows precise modifications to DNA; and DNA sequencing technologies, such as next-generation sequencing, which determine the order of nucleotides in DNA. Other notable technologies include DNA microarrays, used for gene expression profiling, and synthetic Biology techniques that enable the design and construction of new biological parts and systems. These technologies have applications in medicine, agriculture, forensics, and biotechnology.
