Why does DNA replication happen before cell division? What is accomplished by DNA replication? What happens when cells are infected by an RNA virus? What is the first stage of the lytic cycle? What is the first step in eukaryotic DNA replication?
What is the role of the spindle in mitosis? Explain why both mitosis and meiosis are necessary parts of the cell cycle. What are the three reasons why you would do mitosis? a. What would happen if mitosis were uncontrolled? b. Why are chromosomes important? c. What information do they ...
What happens at G2 of Interphase in preparation for mitosis? What would happen to the progeny of a cell that proceeded to mitosis and cell division after entering S phase but not had completed S phase? Keep in mind that highly condensed chromatin, including the centromere region, is replicated...
What must happen before meiosis can begin? What happens in meiosis I that does not occur in meiosis II? In what stage of meiosis does trisomy 21 occur? In meiosis, what makes up a tetrad? What is chiasmata in meiosis? How do you determine when nondisjunction occurs? What does meiosis s...
Most cells spend the majority of their time in interphase, which consists of the G1, S, and G2 phases. During interphase, a cell grows, duplicates its chromosomal DNA, and prepares to divide. As its name suggests, DNA replication (i.e., synthesis) occurs during the S phase. During ...
After ejaculation, the first several hours leading to fertilization happen before the sperm cells and egg cell even meet. Approximately 180 million sperm cells congregate in the reproductive tract, shedding excess proteins that ejaculated with them and reorganizing their plasma membranes until they are ...
During interphase, the cell grows and develops the proteins needed for cell division. In the middle of the interphase period, the cell duplicates itschromosomes.Once the chromosomes have been duplicated and all other conditions are ideal in the cell, the first phase of mitosis can begin!
a. What would happen if mitosis were uncontrolled? b. Why are chromosomes important? c. What information do they provide? What is the importance of chromosomes to a cell? Mitosis and meiosis are important processes. \\ a) What does each accomplish; \\ b) where in the human body can eac...
a. What would happen if mitosis were uncontrolled? b. Why are chromosomes important? c. What information do they provide? How does cell division and cell growth play a role in the life of a cell? Explain why it's so important that the zygote undergo mitosis properly. ...
