Secondary tetrasomic segregation of MDH-B and preferential pairing of homeologues in rainbow trout.

abstract：:Animal microRNAs (miRNA) are implicated in the control of nearly all cellular functions. Due to high sequence redundancy within the miRNA gene pool, loss of most of these 21- to 24-bp long RNAs individually does not cause a phenotype. Thus, only very few miRNAs have been associated with clear functional roles. We cons...
