Cell Cycle MCQs
Hello students, the topic for the next MCQ is ‘Cell cycle’. There are a lot of life cycle occurs in the body of organisms. We know how the small organisms are modified into large organisms and also some organisms go through different transformations. All this processes are possible because of cell divisions and cell cycles. We also know, all the organisms do start their life with a single cell. So, how this happens and how a single cell creates a large organism.
