BROWSING BIOLOGICAL DATABASES

  1. + - gives access to more information
  2. Symbol - identifies the gene name
  3. Description - access to the respective description
  4. GC id - is the identification number in the GeneCards database
  1. Chromosome where the gene is located
  2. The size of the gene
  3. The orientation of the DNA strand in which the gene is located
  1. Biological information stored in the first database that appears in this Section
  2. Number of amino acids encoded by gene OPN1LW
  3. Cellular compartment where this protein is located
  4. Accession number/Identifier of the protein in this database
  1. Diseases[2] in which the gene is involved.
  1. Known mutations to the OPN1LW gene.

You have finished an excursion through some of the biological databases.

However this is only the starting point for a more detailed study on genes involved in vision, specifically the OPN1LW gene.

Here you learned this gene is on chromosome X.

  • But, which is the nucleotide sequence?
  • What is the structural organization of this gene?
  • Does it have introns?
  • How is it regulated?
  • These exercises are the proposals for the next research project: How is the opsin gene organized?
