CRISPR/Cas9-mediated mutation of tyrosinase (Tyr) 3′ UTR induce graying in rabbit

Abstract The 3′ untranslated regions (UTRs), located at the end of mRNA molecules, are believed to play a role in RNA replication and/or protein translation. Mutations in the tyrosinase (Tyr) gene are known to cause recessive albinism in humans and other species. In this study, to test whether the C...
