Racial/ethnic minority individuals, women and persons with disabilities are encouraged to apply as principal investigators. ELIGIBILITY REQUIREMENTSĪpplications may be submitted by domestic and foreign, for-profit and non-profit organizations, public and private, such as universities, colleges, hospitals, laboratories, units of state and local governments, and eligible agencies of the federal government. The resources produced will be used to further studies of diseases and other biological phenomena. The National Human Genome Research Institute (NHGRI), formerly the National Center for Human Genome Research, solicits applications for research projects to develop new technologies, and/or significantly improve existing technologies, that will facilitate and accelerate the genome mapping, sequencing and analysis goals of the Human Genome Project (HGP) in the most expeditious and economical manner. 10, Maand (PA-92-59) Genome Informatics Program, NIH Guide for Grants and Contracts, Vol. NOTE: This program announcement supersedes the following two program announcements: (PA-94-045) New and Improved Technologies for Genomic Mapping and Sequencing, NIH Guide for Grants and Contracts, Vol. NIH GUIDE,Volume 26, Number 8, March 14, 1997 Nature protocols, 2017, 12(2): 213.Technologies for Genomic Mapping, Sequencing and Analysis Additionally, DNA sequencing can be used for protecting and improving the natural environment for both humans and wildlife. Sequencing has the power to revolutionize food safety and sustainable agriculture including animal, plant and public health, improving agriculture through effective plant and animal breeding and reducing the risks from disease outbreaks.

Notably, DNA sequencing can reveal changes in a gene that may cause a disease.ĭNA sequencing has been used in medicine including diagnosis and treatment of diseases and epidemiology studies. Homologous DNA sequences from different organisms can be compared for evolutionary analysis between species or populations. The DNA sequence can be screened for characteristic features of genes, such as open reading frames (ORFs) and CpG islands. Scientists can use sequence information to determine which genes and regulatory instructions are contained in the DNA molecule. The history of DNA sequencing technologies.Īpplications of DNA Sequencing TechnologiesĭNA sequencing reveals the genetic information that is carried in a particular DNA segment, a whole genome or a complex microbiome. Long-read methods can detect more variations, some of which cannot be observed with short-read sequencing alone.įigure 1. NGS is a short-read sequencing that requires the construction of small fragment library, followed by deep sequencing, raw data preprocessing, DNA sequence alignment, assembly, annotation, and downstream analysis.Įmerging third-generation sequencing, also known as long-read sequencing including PacBio SMRT sequencing and Oxford nanopore sequencing, can examine billions of templates of DNA and RNA and simultaneously detect variable methylations without bias. NGS can determine the order of millions of fragments simultaneously. Next-generation sequencing (NGS, also known as massively parallel sequencing) technologies have largely supplanted Sanger sequencing with advantages such as high throughput, cost efficiency, and rapidness. You can view our article ‘ Sanger Sequencing: Introduction, Principle, and Protocol‘ to learn more about this method.

Sanger method is a classical DNA sequencing method that utilizes fluorescent ddNTPs (dideoxynucleotides, N = A, T, G, or C) to prevent the addition of another nucleotide. Sanger sequencing was discovered by English biochemist Frederick Sanger in the 1970s. Thanks to the tremendous improvement in DNA sequencing technologies and methods, whole genome sequencing has become possible and affordable.

This complementary base-pairing is the basis for the mechanism by which DNA molecules are copied, transcribed and translated, and the pairing also underlies most of DNA sequencing methods. The based-paired structure makes DNA sequence well suited to the storage of a vast amount of genetic information. The human genome contains around 3 billion base pairs that provide the instructions for the creation and maintenance of a human being. Adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). In the DNA double helix, the four bases bond with the specific partner to form units called base pairs (bp). DNA Sequencing is the method that determines the order of the four nucleotides bases (adenine, thymine, cytosine, and guanine) that make up the DNA molecule and convey important genetic information.
