I'm not a professional biologist, I'm just trying to analyze some actual data. Where should I look up the location of a gene and nucleotides it consist of? How can I find it in DNA? Is there an algorithm that can be used?

    $\begingroup$ This is not clear. You have a gene and its sequence? You have a gene name and a genome sequence that could or could not have this gene? What type of "gene name" do you have? There are different identifiers for genes. If it is a standardised one, yes, you can get the gene sequence for example from Genbank and you can align the gene to a genome. But please try to make the question more specific and add more research. $\endgroup$ – skymningen Dec 14 '16 at 9:58

To find the genomic location of a gene when you start with a gene name;

Use the UCSC Genome browser. This has a number of advantages. There are a number of species to choose from. It provides a representative image of the gene and regulatory elements that surround it. It can display a lot of extra information if you want to see it. The disadvantage ot the UCSC Genome browser is that the information density may overload non-professional users.

To find the genomic location of a gene when you start with a DNA sequence;

Use the search tool that links to the UCSC browser.

The alternative option is to search for your gene ID or sequence in NCBI Gene.

To search for a DNA nucleotide sequence using the link above, select Reference genomic sequences (refseq_genomic) from the pull-down tab in the Database field. Limiting the search to a species using the Organism field is also wise.

Both of these sites provide the information you are after. Taking time to read the help instructions will be useful.
