The user began with a broad query of the term sensory, which returned all items from all sources mentioning that term, including the formal literature, informal literature, gene descriptions, sequence annotations, and so on. The relationship links to this literature article were then followed to retrieve a set of gene descriptions. Not shown is a further interaction made possible by using an analysis program on the sequence to display its coding regions. Courtesy of Bruce Schatz, University of Arizona. Replication is the process in which existing DNA is used as a template for the synthesis of new DNA strands.
Mutagenesis is the process by which DNA is mutated or modified.
Translation is the process in which the genetic code directs the synthesis of proteins from amino acids. PCR is a method for increasing the number of copies of a specific DNA fragment to make the fragment easier to detect and identify. Gel electrophoresis is a method of separating large molecules in an electric field, allowing DNA fragments differing by single bases to be readily separated. Combined with methods such as Sanger's dideoxynucleotide chain termination procedure, gel electrophoresis can produce ladders of DNA molecules from which DNA sequences can be determined. After mapping is completed, the next step is to determine the sequence of base pairs of the ordered DNA fragments.
