g After it is phosphorylated, SRSF1, a splicing factor, binds to an exon splicing enhancer in the VEGF mRNA and promotes splicing at exon 8a rather than 8b. How might VEGF splicing be affected if the cell is expressing a mutant SRSF1 in which the amino acids normally phosphorylated are changed to glutamate, and is not expressing the wild type form of SRSF1

Works together in the synthesis, modification, packaging, and transport of lipids and proteins

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
