What is the genome database?
genome is a collection of all genetic material present in one organism. Because the sequence and structure of this genetic material control the whole biological life, scientists are very interested in finding out what everyone is for. The genome database is a cross -referenced collection of information about one or more organisms, so one scientist can look at all available genetic information that will help him in research. Computer databases are therefore the only practical way to organize details in one place. In general, they are available as an online database for scientific research. The relatively new scientific area, called bioinformatics, has emerged to improve the way biological data can be interpreted through computer systems.
Genomes database contain the sequence of the body of the organism, as far as the whole sequence is known. Otherwise, it may contain partial sequences. For example, human, mouse and Drosophila were sequential. When the sequence of the genome is known,Genetics can identify specific genes in the genome. Each gene is an instructional sheet for one particular cell product.
If the gene has a mutation, it has a different sequence than a normal functional gene. Mutations can be beneficial and produce useful characteristics in the mutated organism. They cannot also not change the product or can be harmful to the normal functioning of the body. For example, many health conditions are caused by mutations in a particular gene.
mutations can also be used to calculate how closely related a species to another is because more mutations have accumulated over time. Individuals may also differ in the genomic sequence, especially because large parts of the genome are not genes and non -code -f or any basic cell product. The genome database holds the sequence from the body that is marked as standard, but between arbitrarily selected standard and other individuals in species will be many smallerthe differences.
Despite the presence of many differences, genes are recognizable through sequences. If geneticists know what a particular gene is doing in one organism, then a sequence gene in another animal is likely to perform the same function. Genetics can use the genome database either to identify the gene they study or to find out what the gene is doing.
Every genome database is searched. Scientists can usually search the database in one of several different ways. It can usually enter the sequence of the gene they sequence. Then the database finds one or more similar sequences for comparison.
The easier way of searching for a database involves searching for a keyword of a gene such as a gene name. Authority, such as the US National Office for Biotechnology Information (NCBI), can provide sequences of different reference numbers, and a geneticist can also search the genome database using one of these identifiers. It can also narrow the results using multiple search parameters. Information aboutCross reference is the function of most of the genome databases and the result of a single sequence also provides users useful links for more genetic information. Like information about a particular sequence, it provides many databases of visual representation of the sequence and remarkable properties of this area.
different organisms may have specific genome databases, but some larger databases contain more than one species. Different authorities control different available databases, so databases can all use different formats and search skills. The examples of these authorities include NCBI, the European Bioinformatic Institute or even individual universities.
