The majority of a cell's life is spent in interphase, where it undergoes three processes: Gap 1 Phase (G1), Synthesis Phase (S), and Gap 2 Phase (G2). G1 phase-the cell will grow in size and replicate organelles S phase-DNA is replicated G2 phase-the cell prepares for cell divi...
Mitosis:During the first mitotic stage, known as prophase,chromatincondenses into discrete chromosomes, the nuclear envelope breaks down, andspindle fibersform at opposite poles of the cell. A cell spends less time in prophase of mitosis than a cell in prophase I of meiosis. Meiosis:Prophase I ...
Meiosis is similar to mitosis in many ways, but there are a couple of important differences. First of all, even though meiosis starts with a diploid cell (a primary oocyte or primary spermatocyte), its end products are 4 haploid daughter cells, each with 23 chromosomes. Instead of being c...
During which stage of the cell cycle is the DNA replicated? a. Mitosis. b. S. c. G2. d. Cytokinesis. Cell Cycle: The cell cycle is the steps taken during a cells life cycle. The cell cycle is divided into interphase, mitosis and cytokinesis. The...

Chromosomes are introduced right at the start, which is in fact an account of mitosis and meiosis. Then follows what comes to seem almost like a digression, into the inter-relations of heredity, environment and character, before the main trend is resumed with an account of mendelian behaviour....
英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
Mitosis and meiosis are both processes of cell division, but they differ in terms of the number of daughter cells that are...
Cells are of only two fundamental kinds: bacteria (=prokaryotes; cells with DNA segregated by surface membrane motors) and eukaryotes (nucleated cells dividing by mitosis) [1,2]. In bacteria the typically single and circular DNA chromosome is attached to the surface cytoplasmic membrane and segrega...
mitosis involves breaking down thenuclear membranethat surrounds the cell’s DNA so that the DNA can be replicated and separated into new cells. Other types of cells, likeprokaryotes, don’t have a nuclear membrane surrounding their cellular DNA, which is why mitosis only occurs in eukaryotic ...
