How many methods are used in DNA sequencing?
Since the birth of DNA sequencing in the 70's several methods have been developed which have become increasingly more efficient. There are probably 10-15 mainstream ways of sequencing, although dye-terminator sequencing is the one primarily used
What is the process used for DNA Sequencing?
There were initially two methods used for DNA sequencing, but today there are dozens. Genome sequencing is defined as any process that determines the order of nucleotides within an atom of DNA. It is almost always accomplished automatically in modern applications, using machines specifically designed for the job.
What are the techniques used in DNA sequencing?
A common approach to DNA sequencing is through a process called Sanger sequencing, named after its inventory, Frederick Sanger. To describe the process simply, a sample of purified DNA is treated with a solution of enzymes, nucleotides, and terminators to duplicate the strands of DNA. As the DNA is being copied, it uses the nucleotides to form new strands of DNA and sometimes will add a terminator which stops the duplication process at varying lengths. The terminators are labeled with a radioactive or fluorescent chemical which allows them to be detected by a scanning machine. In capillary electrophoresis, the mixture of varying length DNA is separated in a very narrow tube and as each terminator passes by the detector, the sequence of the DNA bases can be read. For a more detailed description of the mechanics of Sanger sequencing, an internet search will yield many results.
What are some companies that provide DNA sequencing services?
Companies that provides DNA sequencing services would include companies such as Operon, Nucleics, and Sanger Sequencing Service. There are many other companies who offer this service as well.
What types of DNA sequencing in their DNA?
The types of DNA sequencing are whole-genome sequencing which maps entire DNA sequences, targeted sequencing which focuses on specific genomic regions, and RNA sequencing which identifies gene expression levels.

What are the methods of biological investigations?
Some methods of biological investigations include microscopy, DNA sequencing, immunohistochemistry, and cell culture techniques. These methods allow researchers to study various aspects of living organisms, such as their structure, function, and interaction with the environment.

Who discovered the technique of DNA sequencing?
DNA sequencing was first discovered by Fredrick sanger in 1950s

Companies that provides DNA sequencing services would include companies such as Operon, Nucleics, and Sanger Sequencing Service. There are many other companies who offer this service as well.
What are the benefits of automated DNA sequencing?
DNA sequencing enables the scientists to determine genome sequence. Human genome projects is the biggest example of DNA sequencing. When the human genome was sequenced back in 2001, many issue rose but now after many years, we can see it's impacts on medical and pharmaceutical research.
Describe what is meant by the term rapid sequencing?
Sequencing DNA rapidly
What are some discoveries that have been made as a result of DNA sequencing?
birth control.
What is DNA sequencing used for in relation to pregnancy?
Some couple are using DNA sequescing to select things such as gender, skin color, size, and eye color of their unborn baby. A lot of doctors discourage this type of DNA sequencing.
How can one determine the gene sequence of a specific organism?
To determine the gene sequence of a specific organism, scientists use a process called DNA sequencing. This involves isolating the DNA from the organism, breaking it into smaller fragments, sequencing these fragments, and then assembling the sequences to determine the complete gene sequence. Various technologies and methods, such as next-generation sequencing, are used to accurately determine the order of nucleotides in the DNA.
What does not read DNA sequences?
People not versed in DNA sequencing.
