Metaphase is the phase of cell division where chromosomes line up on the equator of the cell just prior to splitting to the poles at anaphase. During mitosis identical chromosomes pair up on the equator, wheras during meiosis the homologous pairs line up together during meiosis 1 and then homologous chromatids line up together in meiosis 2.
What else can I help you with?
What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
What are some characteristics of mitosis and not meiosis?
In mitosis, cell division creates two diploid cells, while in meiosis, cell division creates two haploid cells. In metaphase of mitosis, a pair of chromosomes meet in the middle of the cell. during anaphase, the pair seperates. In meiosis, the chromosomes line up individualy in metaphase and separate in anaphase. Mitosis is cell division for all cells in the body except gamete cells. Meiosis is cell division for gamete cells.
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
Summarize what happens during interphase?
Interphase is the stage in which the cell grows, matures, and replicates its DNA. It is divided into three phases - G1, S, and G2. During interphase the cell prepares itself for cell division.
Why is metaphase the longest stage in mitosis?
Metaphase is the stage of mitosis in which the all of the cell's chromosomes align along the equator of the cell. It is the final stage before the cell splits into two daughter cells.
At what phase does a spindle develop during cell division?
A spindle develops during the metaphase stage of cell division.
During what phase do the chromosomes move to the center of the cell aligned on the spindle apparatus?
This happens during metaphase. I remember this phase because it is the move phaseof mitosis. The m from move matches the m from metaphase.In mitosis, it happens during metaphase.In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2.
How do homologous pairs of chromosomes line up at the metaphase plate during metaphase II in cell division?
During metaphase II of cell division, homologous pairs of chromosomes line up individually at the metaphase plate, with one chromosome from each pair on either side of the plate. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.
What is the phase when chromosomes are lined up in the middle of the cell called?
The phase where chromosomes are lined up in the middle of the cell is called metaphase. During metaphase, the chromosomes align along the cell's equator before they are separated into two sets during cell division.
Chromosomes line up across the middle of the cell?
during cell reproduction the "mother cell" makes a copy of chromosomes and then divides them evenly between two "daughter cells" so the chromosome pairs line up in the center of that division.
Stage when chromosomes align in one plane?
Metaphase is the stage of cell division when chromosomes align in one plane along the center of the cell. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.
In what ways are metaphase 1 and metaphase 2 similar in the process of cell division?
Metaphase 1 and metaphase 2 are similar in that both stages involve the alignment of chromosomes along the cell's equator. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
What happens to cell membranes during cell division?
During prophase the nuclear membrane disintegrates. The metaphase through anaphase the molecules are not formed as membranes. During telophase it reintegrates and in interphase it is present as normal.
When and how is the spindle formed?
The spindle is formed during cell division, specifically during the metaphase stage of mitosis or meiosis. It is made up of microtubules and associated proteins, organized by the centrosomes at opposite poles of the cell. These microtubules help to separate chromosomes during cell division.
Phase of mitosis during which chromosomes move to the middle of the cell?
The phase of mitosis during which chromosomes move to the middle of the cell is called the metaphase. In metaphase, the chromosomes align along the metaphase plate, forming the spindle apparatus. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.
Which phase is directly affected when a cancer drug interferes with the development of mitotic spindle fibers during cell division?
The phase that is directly affected is the metaphase of cell division. Mitotic spindle fibers play a crucial role in aligning chromosomes at the cell's equator during metaphase, and disrupting their development can lead to chromosome misalignment and cell division failure.
