Which of the following statements are correct? Explain your answers. Cells do not pass from G1 into M phase of the cell cycle unless there are sufficient nutrients to complete an entire cell cycle. Apoptosis is mediated by special intracellular proteases, one of which cleaves nuclear lamins. Developing neurons compete for limited amounts of survival factors. Some vertebrate cell-cycle control proteins function when expressed in yeast cells. The enzymatic activity of a CDK protein is determined both by the presence of a bound cyclin and by the phosphorylation state of the CDK.
