title: Recognition of ill-defined signals in nucleic acid sequences.
abstract: A set of programs has been developed for the definition and handling of nucleic acid sequence consensus information. The sequences of known genetic control signals are combined in a matrix. The origins and positions of the signals are recorded. Old matrices can be updated dynamically: new signals are included and obsolete ones deleted. Matrices of several different types are computed optionally. Several of these matrices can be combined to find possible new signals. The use of matrices allows the exact quantification of signal qualities. The described programs are part of a program library named GENEXPERT. Application examples given are the search for tRNA genes and the search for promoters in the bacteriophage lambda genome.
