Abstract
In order to facilitate and speed up the search of massive DNA databases, the database is indexed at the beginning,
employing a mapping function. By searching through the indexed data structure, exact query hits can be identified. If the
database is searched against an annotated DNA query, such as a known promoter consensus sequence, then the starting
locations and the number of potential genes can be determined. This is particularly relevant if unannotated DNA sequences
have to be functionally annotated. However, indexing a massive DNA database and searching an indexed data structure
with millions of entries is a time-demanding process. In this paper, we propose a fast DNA database indexing and
searching approach, identifying all query hits in the database, without having to examine all entries in the indexed data
structure, limiting the maximum length of a query that can be searched against the database. By applying the proposed
indexing equation, the whole human genome could be indexed in 10 hours on a personal computer, under the assumption
that there is enough RAM to store the indexed data structure.
