cord-256320-zocunore	Liao, Bo	Coronavirus phylogeny based on triplets of nucleic acids bases	2006-04-15		.txt	text/plain	1972	171	72	Abstract We considered the fully overlapping triplets of nucleotide bases and proposed a 2D graphical representation of protein sequences consisting of 20 amino acids and a stop code. Based on this 2D graphical representation, we outlined a new approach to analyze the phylogenetic relationships of coronaviruses by constructing a covariance matrix. Based on these graphical representation, several authors outlined some approaches to make comparison of DNA sequences [21] [22] [23] [24] [25] . In this Letter, we proposed a 2D graphical representation of the protein sequences consisting of 20 amino acids and a stop code. Using the translate tool, we can obtain three protein sequences consisting of 20 amino acids and a stop code. Using the translate tool, one can obtain three protein sequences consisting of 20 amino acids and a stop code corresponding three reading frame start at position 1, 2 and 3. The current two-dimensional graphical representation of DNA sequences provides different approach for constructing phylogenetic tree.	./cache/cord-256320-zocunore.txt	./txt/cord-256320-zocunore.txt
