A mutation is a permanent change in the DNA sequence of a gene. Mutations in a gene's DNA sequence can alter the amino acid sequence of the protein encoded by the gene.
Connectivity Map. This research effort aims to generate a detailed map that links gene patterns associated with disease to corresponding patterns produced by drug candidates and a variety of genetic manipulations.The Connectivity Map is the most comprehensive effort yet for using genomics in a drug-discovery framework.his research effort aims to generate a detailed map that links gene patterns associated with disease to corresponding patterns produced by drug candidates and a variety of genetic manipulations.
mapping. DNA mapping refers to the variety of different methods that can be used to describe the positions of genes. DNA maps can show different levels of detail, similar to topological maps of a country or city, to indicate how far two genes are located from one another.
