In gene sequencing the nucleotide strained with fluorescent dye are:
Correct answer: C. Terminating nucleotides
- A. Initiation nucleotides
- B. Middle nucleotides
- C. Terminating nucleotides
- D. None of the above
Explanation
DNA sequence is now completely automated, robotic devices mix the reagents andthen load, run and read the order of the nucleotide bases from the gel. This is facilitatedby using chain terminating nucleotides that are each labelled with a diferent coloredfluorescent dye; in this case, all four synthesis reactions can be performed in the sametube, and the products can be separated in a single lane of a gel.

About Biotechnology
Biotechnology in health care applies biological organisms, cells or enzymes to diagnose and treat disease. The subject includes recombinant DNA, genetically engineered insulin, vaccines, antibiotics, monoclonal antibodies, gene therapy and techniques such as polymerase chain reaction, while distinguishing therapeutic applications from agricultural and industrial biotechnology.
