This supports the idea that in embryos from wild-type mothers, dpp H~- mutations cause the transformation of dorsal into ven-tral epidermis. If tissue determined to become dorsal epidermis dies in the dpp rim-null embryos, then one should not see ventral or lateral tissue formed in the double-mutant combination.
DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. Small amounts of dystrophin are present in nerve cells in the brain.In skeletal and cardiac muscles, dystrophin is part of a group of proteins (a protein complex) that work together to strengthen muscle fibers and protect them from injury as muscles contract and relax.he official name of this gene is âdystrophin.â. DMD is the gene's official symbol. The DMD gene is also known by other names, listed below. Read more about gene names and symbols on the About page.
