Alternative pre- mRNA processing of the rat-tropomyosin gene

Alternative pre- mRNA processing of the rat-tropomyosin gene. Alternative splicing patterns are indicated by the bent lines connecting exons. Nine distinct mature mRNAs produced by different types of muscle, brain, and fibroblast cells each produce a different tropomyosin protein (1 of 3)Alternative pre- mRNA processing of the rat-tropomyosin gene.
