What is the significance of DNA sequencing technologies?

The significance of DNA sequencing technologies primarily lies in their ability to provide rapid and precise determination of the nucleotide sequence in DNA. This capability enables researchers and clinicians to understand genetic information at an unprecedented level of detail. By determining the exact sequence of nucleotides—adenine, cytosine, guanine, and thymine—scientists can identify genetic variations, mutations, and the overall genomic landscape of organisms. This information is crucial in various fields, including genetics, personalized medicine, evolutionary biology, and pharmaceutical development, making DNA sequencing a foundational tool in modern biotechnology.

The other options do not accurately capture the breadth and impact of DNA sequencing technologies. While they contribute significantly to many areas, they do not fully encapsulate the connection of sequencing technologies to a wide range of scientific and diagnostic applications.
