60. Genomic Imaging Based on Codongrams and a2grams
This paper introduces new tools
for genomic signal processing, which can assist for genomic attribute extracting
or describing biologically meaningful features embedded in a DNA.
The codongrams and a2grams are offered as an alternative to spectrograms and scalograms.
Twenty different a2grams are defined for a genome, one for each amino acid. valgram is an a2gram for valine; alagram is an a2gram for alanine and so on.
They provide information about the distribution and occurrence of the investigated amino acid. In particular, the metgram can be used to find out potential
start position of genes within a genome. This approach can help implementing a new diagnosis test for genetic diseases by providing a type of DNA-medical imaging.
