(b)Meiosis is another type of nuclear division.Describe how the nuclei in cells produced by meiosis differ from the nuclei in cells produced by mitosis.-[3](c) Stem cells divide by mitosis during the growth of an embryo.Describe the role of stem cells in the growth of an embryo.-[2]...
2. Mitosis Overview: Mitosis is an equational cell division where one mother cell divides to produce two identical daughter cells. Both the mother and daughter cells have the same diploid number of chromosomes (2n). This means there is no variation in the genetic material. 3. Meiosis Overview...
What is the term used for the failure of homologous chromosomes to separate during cell division? What are the types of cell division in unicellular organisms? Which type of cellular division results in the formation of diploid cells from a diploid parent cell? Sel...
What type of cell division occurs in gametes (sex cells)? It makes reproductive cells and results in four cells with half the number of chromosomes as the parent cell.In what type of cell does each form of cell replication occur (mitosis and meiosis)? What are the purposes of ...
The type B cells in mitosis extend across alveolar septa as well as along the alveolar surface. The extension of type B cells through alveolar septa is not limited to cells in mitosis, but is also observed in non-mitotic type B cells. Stimulation of mitosis and hyperplasia of type B cells...
Abstract According to the current model of adult epidermal homeostasis, skin tissue is maintained by two discrete populations of progenitor cells: self-renewing stem cells; and their progeny, known as transit amplifying cells, which differentiate after several rounds of cell division1,2,3. By making...
They are generated as a biproduct of cellular respiration and the can damage DNA and other structures. Answer and Explanation: The correct answer is (a) Oxidation. Reactive oxygen species, including hydroxyl radicals, contain oxygen atoms that ...
Second, HTLV-1 infection can cause the insertion of efficient oncogenes into the host genome, which reduce the expression of tumor suppressor genes or directly stimulate mitosis of the host cells[24]. Third, HTLV-1 infection can also inhibit the host immune function and impair immune ...
cells, and expression levels of individual genes within each cell can then be determined. This approach enables the expression profiles of thousands of individual cells to be analyzed, and the cells can then be grouped (clustered) based on their similarities. The groups of cells thus identified ...
Ions shaping the mechanics of chromosomes in mitosis Ions play a key role in governing the viscoelastic properties and mechanical stability of mitotic chromosomes. Wenmao Huang ,Zongqing Lim &Jie Yan Letter|29 October 2024 Demonstration of efficient Thomson cooler by electronic phase transition ...
