Under favorable conditions, a plant cell can divide asexually by mitosis into two identical cells. The upside of mitosis is rapid growth. The downside of mitosis is limited biodiversity, which can be detrimental to survival if conditions change. Higher order plants can also reproduce sexually throu...
Mitosis is a fundamental process for life. During mitosis, acell duplicatesall of its contents, including its chromosomes, and splits to form two identical daughter cells. ... When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have th...
One of the most important characteristics of living cells is to undergo division through processes called mitosis or meiosis.Answer and Explanation: In unicellular organisms, cell division allows the cell to divide into two or more daughter cells, and thus it is essential for the reproduction of....
What roles do meiosis and mitosis play in the production and development of an embryo? How does haploid cells meiosis? Why is the process of mitosis and meiosis both important to living organism? Why do the daughter cells produced from meiosis 1 need to divide again in meiosis 2 ...
Mitosis does occur in adult cardiac myocytes. Reports that a study has challenged the long standing belief that adult ventricular myocytes are terminally differentiated cells and therefore incapable of... Moore,Peter - 《Lancet》 被引量: 0发表: 1998年...
During mitosis cells can divide symmetrically to proliferate or asymmetrically to generate tissue diversity. While the mechanisms that ensure asymmetric cell division have been extensively studied, it is often assumed that a symmetric cell division is the default outcome of mitosis. Recent studies, ...
The cells were unable to complete mitosis and divide. In the presence of the protein kinase inhibitor starosporine, the addition of fostriecin did not induce histone phosphorylation and chromosome condensation. The results show that chromosome condensation can take place without either the histone ...
The stratum basale or stratum germinativumundergoes constant mitosis to replace the cells exfoliated from the skin's surface. Does circumcision cause Keratinization? Circumcision results in a process calledkeratinization, whereby the top layer of the inner foreskin becomes thicker, which may provide add...
Dox-treated p27WT and p27C cells accumulated in G0/G1 (Figure 2b). This finding dovetails with the limited expression of cyclin A and cyclin B1 in these cells: cyclins A and B are expressed in S/G2 and mitosis, respectively. Dox-treated p27WT and p27C cells did not double in ...
Why does the secondary oocyte divide unevenly?Oogenesis:Oogenesis is the process of making eggs from germ cells in female organisms. Oogenesis involves two cell divisions during the process of meiosis to produce one functional ovum and three polar bodies that eventually disintegrate....
