All three RNA recognition motifs and the hinge region of HuC play distinct roles in the regulation of alternative splicing.

abstract：:The web software CHOP was developed to visualize the 'wobbling' in the third codon position of aligned DNA sequences. The simple features of this tool allow users to easily find regions suspected of containing coding sequences (CDSs). The program also allows visualization of the nucleotide diversity between two genomi...
