Genomics

Genomics is an area within genetics that concerns the sequencing and analysis of an organism's genome. The genome is the entire DNA content that is present within one cell of an organism. Experts in genomics strive to determine complete DNA sequences and perform genetic mapping to help understand disease.Genetics involves scientific studies of genes and their effects. ... Genomics is a more recent term that describes the study of all of a person's genes (the genome), including interactions of those genes with each other and with the person's environment.Genomics is the study of whole genomes of organisms, and incorporates elements from genetics. Genomics uses a combination of recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyse the structure and function of genomes.Each genome contains all of the information needed to build that organism and allow it to grow and develop. ... Each cell in the body, for example, a skin cell or a liver cell, contains this same set of instructions: The instructions in our genome are made up of DNA.Gaining a better understanding of the interactions between genes and the environment by means of genomics is helping researchers find better ways to improve health and prevent disease, such as modifying diet and exercise plans to prevent or delay the onset of type 2 diabetes in people who carry genetic predispositions.Genomics is the study of whole genomes of organisms, and incorporates elements from genetics. Genomics uses a combination of recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyse the structure and function of genomes.The most commonly-known application of genomics is to understand and find cures for diseases. Predicting the risk of disease involves screening currently-healthy individuals by genome analysis at the individual level. ... The scientists used databases and several publications to analyze the genomic data.First, the genome must be selected, which involves several factors including cost and relevance. Second, the sequence is generated and assembled at a given sequencing center (such as BGI or DOE JGI). Third, the genome sequence is annotated at several levels: DNA, protein, gene pathways, or comparatively.Genomics is an interdisciplinary field of molecular biology focusing on the DNA content of living organisms. ... High-throughput DNA sequencing technologies and bioinformatics have transformed genome analysis by mapping and decrypting coding and non-coding DNA sequences, their evolution and inter-relationships.
