CodonO: codon usage bias analysis within and across genomes.

abstract：:NELF and DSIF act together to inhibit transcription elongation in vitro, and are implicated in causing promoter proximal pausing on the hsp70 gene in Drosophila. Here, further characterization of Drosophila NELF is provided. Drosophila NELF has four subunits similar to subunits of human NELF. The amino acid sequences ...
