MOTIFS MOTIFSMARTIFAMORIFSMOOTIFSMICIFC

MOTIFS MOTIFSMARTIFAMORIFSMOOTIFSMICIFC. A sequence motif is a nucleotide or amino-acid sequence pattern that is widespread (repeated) and has or is conjectured to have a biological significance. Sequence motifs may be identical to each other or they may vary to a greater or lesser extent. .
