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 mitosis, a cell divides and splits its entire contents (including its chromosomes) between two daughter cells.As...
What happens during anaphase in mitosis? Why is it important that the chromosomes are doubled ("copied") before mitosis? What are the main differences between mitosis and meiosis? Why is interphase important before cell division begins?
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! The 4...
Why does meiosis consists of two cell divisions? What is the function of mitosis? Explain in detail. What would be the result of a cell undergoing mitosis but not cytokinesis? Discuss the importance of meiosis. Explain why interphase must precede any type of cell division. How is somatic cell...
A few more things also happen during prophase: the nuclear envelope that separates the nucleus from the rest of the cell dissolves, the nucleolus disappears, and structures called centrosomes migrate to each end of the cell. The centrioles within the centrosomes sprout spindle fibers (microtubules...
TheIce Age (and its resulting changes in climate)was among one of the harshest periods on Earth. During an ice age, the earth experiences colder temperatures than normal as well as glacial expansion, along with at least one major ice sheet. Depending on the extent of these two factors, an...
