The extra set of chromosomes is obtained by replicating the original pair. The two chromosomes end up in different cells at the end of mitosis.
To develop a procedure to identify cancerous tissue based on the number of cells undergoing mitosis, you could obtain a tissue sample, stain it to highlight mitotic cells, and then count the number of cells undergoing mitosis per unit area using a microscope. An increased number of cells undergoing mitosis may indicate abnormal cell proliferation characteristic of cancer. Further validation through histological analysis and comparison with healthy tissue samples would be necessary to confirm the presence of cancer.
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
The first thing geneticists do in order to analyze a human karyotype is to obtain a sample of cells, usually through a blood test. They will then culture the cells in the lab, stop the cells in metaphase of mitosis, stain the chromosomes, and take a microphotograph to examine the chromosomes under a microscope.
Yes, you can obtain health insurance coverage prior to undergoing surgery. It is important to have health insurance in place before any medical procedures to help cover the costs and ensure you receive the necessary care.
There are many differences between meiosis and mitosis, and it can all be summed up by understanding they have different functions in life processes. Mitosis is all about creating cells that are identical to each other asexually. This provides multi-cellularity in multicellular beings. Meiosis, on the other hand, is all about the production of gametes (sex cells) from a single germ cell in order to make sexual reproduction possible. Taking all of this into considering, Mitosis is seen as being a part of a cyclical cell life cycle, so it happens more than once. Meiosis is a process that happens only once for a germ cell largely because it is a process that creates haploid cells from diploid cells. Note that because of these differences Mitosis requires the replication of DNA to occur in order for diploid cells to create more diploid cells. Diploid meaning that a full set of chromosomes are present; human diploid cells would have 46 chromosomes, 23 from the mother and 23 from the father that are paired up with each other. Haploid, would mean 23 human chromosomes in total; with regards to Meiosis, the chromosomes would be a combination of the genes that an individual inherited from his or her parents. In Meiosis, which is divided into two parts, replication of DNA occurs before Meiosis I is carried out, but no replication occurs before proceeding to Meiosis II in order to achieve creating haploid cells.
1) Sacajawea was able to obtain horses and additional guides from the Shoshones because one of her brothers, that she has not seen since she was captured, was a chief, which made her able to get all of the additional guides and horses she needed.
No, you typically need additional forms of identification, such as a driver's license or passport, to obtain an official ID.
They buy them from the city.
Colchicine causes microtubules to depolymerise. During cell division at the metaphase stage condensed chromosomes line up and are then pulled apart to either pole by microtubules. Hence adding colchicine to a cell culture stops cells completing mitosis. This is useful as a means of accumulating metaphases in the culture before harvesting. Typically colchicine (or the less toxic colcemid) is added about 30mins to 1 hour before harvesting, varying depending on cell type, species etc.
No, it is not possible to obtain an ID using only a birth certificate. Additional documentation, such as a driver's license or social security card, is typically required to obtain an official identification card.
Yes, a child with only one parent can obtain a passport, but additional documentation may be required to prove parental consent and custody.
This is additional requirements started by Government Of Maharashtra to harass SC/ST syudents
