During metaphase the chromosomes become attached to the what fibers by means of their what?
spindle fibers, and centromere
What is the stage that the spindle fibers form?
Meosis is a reductional division, which means the primary cell has to divide twice thus giving four haploid cells. Spindle fibers are formed at Anaphase 1 (of the first division cycle) and Anaphase 2 (of the second division)
What does the correct chromosomal condition at prometaphase of mitosis look like?
The correct chromosomal condition at prometaphase of mitosis is when the chromosomes are fully condensed and aligned along the metaphase plate in preparation for segregation. Each chromosome consists of two sister chromatids held together by a centromere. The spindle fibers are attached to the kinetochores on each sister chromatid to ensure proper separation during anaphase.
What is PMATMAT?
PMATProphase Metaphase Anaphase TelophasePMATProcess MaturityPMATPortable Maintenance Access TerminalPMATPure Mathematics (course)PMATProduct Management and Account Team (Sprint)PMATProgram Management Assistance TeamPMATPrimary Mental Abilities Test (cognitive evaluation)PMATPrograms Management Analytics & Technologiesprophase, metaphase, anaphase, and telephase.PMAT refers to the four stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase.Prophase is the first stage of mitosis. Replicated chromosomes condense and the nuclear envelope breaks down. In animal cells, centrioles form spindle fibers while moving towards the poles. In plant cells, spindle fibers also form, though their origin is unknown as plants do not have centrioles.During metaphase (the second stage), chromosomes line up at the center of the cell (the cell equator). Spindle fibers attach to the centromeres, the centers of sister chromatid pairs.During anaphase (the third stage), sister chromatids are pulled away from each other to opposite ends of the cell by the spindle fibers.During telophase (the fourth stage), nuclear envelopes reform around the chromosomes which subsequently uncoil. In addition, the spindle fibers disappear. Finally, in an animal cell, the cell is divided in two by the formation of a cleavage furrow at the center of the cell where the plasma membrane pinches inward. In plant cells, a cell plate is formed along the center of the cell; this cell plate grows until it touches the cell wall, dividing the cell in two.
What does do not spindle a motion mean?
this means do not spindle a motion ....... or else ! ! !
Gametes have what kind of Chromosomes?
Gametes have haploid chromosomes, which means they have half the number of chromosomes of other cells in the body.
How many chromosomes do flatworms have?
it is an eukaryotic which means multicullar
How many chromosomes does the oogonium have?
The oogonium has a diploid number of chromosomes, which means it contains two sets of chromosomes. In humans, the diploid number of chromosomes is 46.
How many chromosomes does a seal have?
Seals typically have a diploid number of 34 chromosomes. This means they have 17 pairs of chromosomes in their cells.
What is fibrous means?
Containing, or consisting of, fibers; as, the fibrous coat of the cocoanut; the fibrous roots of grasses.
What is the medical term meaning pertaining to fibers?
The medical term meaning pertaining to fibers is "fibrous" or "fibrillar."
What happens to centromere in anaphase 1?
In anaphase 1 of meiosis, the centromeres divide, separating the pairs of homologous chromosomes. Each chromosome is then pulled toward opposite poles of the cell by the spindle fibers attached to the centromeres. This results in the distribution of one member of each homologous pair to each daughter cell.
