Document Summary
Myod converts somite cells into myoblasts: myod regulates myogenin and mef gene (regulatory genes, myogenin and mef are responsible for further differentiation of myoblasts into different muscle cells skeletal muscles or cardiac. Maternal effect genes: expressed by the mother during oogenesis: control egg polarity and thus embryo polarity, anterior and posterior structures, bicoid: maternal effect gene for development of thorax and head, transcribed in the. Mutations here = loss of large areas: pair-rule genes: separates into units of two segments each. Mutation = deletion of every other segment in embryo: segment polarity genes: set boundaries and the anterior-posterior axis of each segment in the embryo. Regulated by products of pair rule genes. Mutation here = one segment deleted and the other copied. 42. 7f cell-death genes apoptosis: apoptosis results from gene activation in response to molecular signals from receptors on the surfaces of marked cells, death signal activates receptor inactivation of ced9 protein disinhibition of.
