Why do we do DNA sequencing?

Sequencing is used in molecular biology to study genomes and the proteins they encode. Information obtained using sequencing allows researchers to identify changes in genes, associations with diseases and phenotypes, and identify potential drug targets.

In respect to this, how does DNA sequencing work?

Each piece of DNA was attached to a radioactive label, and an X-ray picture was made of the gel to make the positions of the DNA bands visible. As the DNA pieces move through the gel, the sequencing machine reads the order of DNA bases and stores this information in its computer memory.

Secondly, what is the importance of genome sequencing? Sequencing the whole genome allows researchers to study not only the genes which code for the important proteins that keep our bodies running, but also the regions of our DNA that have other important roles, such as the regulation of our genes.

Secondly, what is required for DNA sequencing?

Its ingredients are similar to those needed for DNA replication in an organism, or for polymerase chain reaction (PCR), which copies DNA in vitro. They include: The four DNA nucleotides (dATP, dTTP, dCTP, dGTP) The template DNA to be sequenced.

What can DNA sequencing tell us?

The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off.
