Figure 4From: A base composition analysis of natural patterns for the preprocessing of metagenome sequencesFrom its base composition, each bacterial restriction site fits into only one of the four spectrum sets, featured by unique color patterns. The motifs of each set are made up by the permutations of one of the following words; AAATTT, AATTCG, CCGGAT or CCCGGG. This result taken from our previous work in [33].Back to article page
