What process occurs to produce 2 cells?
What process occurs to produce 2 cells?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
In which stage of the cell cycle does the cell split into two cells?
cytokinesis
In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just as mitosis is ending, with a little overlap. Importantly, cytokinesis takes place differently in animal and plant cells.
What is the result of telophase?
Telophase I results in the production of two nonidentical daughter cells, each of which has half the number of chromosomes of the original parent cell. Telophase I results in the production of two nonidentical daughter cells, each of which has half the number of chromosomes of the original parent cell.
Does mitosis produce 2 cells?
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
How many egg cells are formed after meiosis?
one egg
Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg in Figure below. A human sperm is a tiny cell with a tail. A human egg is much larger.
How do cells reproduce?
In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
Which stage is the fastest in the cell cycle?
For the characteristic cell cycle time of 20 hours in a HeLa cell, almost half is devoted to G1 (BNID 108483) and close to another half is S phase (BNID 108485) whereas G2 and M are much faster at about 2-3 hours and 1 hour, respectively (BNID 109225, 109226).
What is the result of telophase I and cytokinesis?
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
When does cytokinesis occur in the cell cycle?
23) Scientists obtain cells in various phases of the cell cycle. They obtain a group of cells that have 1 1/2 times more DNA than G1 phase cells. The cells are most likely ________. 23b) Cytokinesis typically begins during the ________ stage of mitosis. 23c) How is plant cell cytokinesis different from animal cell cytokinesis?
What are the functions of ordinary cell division?
Ordinary cell division produces two daughter cells that are genetically identical. This type of cell division is important for all of the following functions EXCEPT A) growth of a multicellular organism. B) cell replacement.
What’s the difference between mitosis and meiosis?
58) One difference between mitosis and meiosis is ________. 59) Which of the following processes occur during meiosis but not mitosis? A) Haploid cells fuse to form diploid cells. B) Haploid cells multiply into more haploid cells. C) Diploid cells form haploid cells.
How is a chromosome constructed in a cell?
B) It is constructed as a series of nucleosomes wrapped around two double-stranded DNA molecules. C) Each chromosome can be a different size in different cell types of an organism. D) It is a single linear molecule of double-stranded DNA plus proteins. It is composed of a single strand of DNA. Chromatin consists of ________.
