Abstract: A two dimensional base map is here generated up from any DNA base sequence input.

Brief introduction: The transcription of base sequences in DNA to the respectively complementary sequences in m-RNA is a secure and high precision communication system across the nuclear membrane. The original genetic biodiversity information is stored in the DNA on the cell nucleus and stays there. The genetic information in m-RNA is recognized by the t-RNA that assembles the proper amino acid according the respective codon of the m-RNA. The r-RNA is the next building intermediate, transcription, translation and bonding occurs and the specific protein is syntethized. The three types of RNA molecules enable the poly peptide chain formation properly either single or with other poly peptide chains to constitute the protein. This operation is performed perfectly and almost with no exceptions. Mutations will result anytime an unperfect copy of DNA occurs, a new biodiversity will be formed.

Base map: the visual recognition of a sequence of thousands of bases in a DNA molecule with a glance is difficult for any observer. The base sequence can be examined by a computer in a very secure operation. With a two dimensional base map as proposed here visual recognition can be very fast. The purpose is not to replace the actual DNA code system, but to show a condensed figure where each base is represented by a small point.

Sensibility test: Any base sequence up to 1000 bases can be used as input in this test. Just click the mouse when the cursor points the proper base button on the applet below. The base map representation is made by one point up or down or right or left to the origin or to the previous input if the base is T or A or G or C, respectively. At any time after the input of n bases, the respective base map can be observed after clicking on the button INPUT MAP. A random base map with n bases can be observed after clicking on button RANDOM MAP. As a selected example the DNA base sequence of the Hendra Virus, (M. Yu, E. Hansson, J. P. M. Langedijk, B.T. Eaton and L.F. Wang; Virology, 251, 227-233, 1998) from base 1 to 1000 can be observed after clicking on the button HeV 0-1000 SEQUENCE or the respectively base map at the button HeV 0-1000 MAP. To test a new DNA base sequence, the old input can be deleted after clicking on the CLEAN INPUT button. This work is an improved and expanded version of a prototype presented at the "DNA Fingerprinting Second International Congress", Belo Horizonte, MG, 9-12/11/92.
