DNA Sequencing. DNA sequencing is the process used to determine the order of nucleotides in a specific DNA molecule. This information is useful for researchers in understanding the type of genetic information that is carried in the DNA, which may affect its function in the body.
In respect to this, what does DNA sequencing tell us?
Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
What is the use of DNA sequence?
It includes any method or technology that is used to determine the order of the four bases—adenine, guanine, cytosine, and thymine—in a strand of DNA. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.
How do you do DNA sequencing?
Smaller molecules move through the gel more rapidly, so the DNA molecules become separated into different bands according to their size. The catch is that electrophoresis can only separate about 500 bases into clear bands—hence the need for chopping DNA up into small pieces in order to sequence it.
