Which cell has a single line of chromosomes?
Single line of chromosomes is formed at the equatorial plate of Metaphase. The chromosomes start moving in the prophase stage by their terminal ends, guided by inner membrane of the nuclear envelop. The chromosomes at metaphase are in thickest form.
Which phase is known as the organization phase in mitosis?
Metaphase!
What phase are the chromosomes lined up on the equatorial plate?
This is the metaphase.
During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
How does independent orientation of chromosome during meiosis increase genetic variation?
Independent orientation of chromosomes refers to the allignment of the homologous chromosomes along the metaphase plate in metaphase I of meiosis. As the pair of chromosomes line up, one inherited from your mother and the other from your father, there are two orientation possibilities of equal probability; each pole has a 50% chance of inheriting one or the other. This is best explained using the sex chromosomes. Males are XY and females are XX. To differentiate these two female X chromsomes, we will call them Xa and Xb. In Metaphase I of meiosis, the chromosomes can be lined up along the metaphase plate (represented as l) as follows: Male: X l Y or Y l X Female: Xa l Xb or Xb l Xa
Which letter correctly identies metaphase l?
B

Metaphase!
What phase are the chromosomes lined up on the equatorial plate?
This is the metaphase.
In which phase does the nuclear envelope disappear?
In the Prophase. Nuclear envelope and nucleolus disappears.
Which phase of mitosis is where the chromosomes are located at the equator of the cell?
Metaphase is the third phase of mitosis, when the chromosomes line up at the equator of the cell.
What phase do chromosomes line up?
During metaphase.A trick is to remember: "M for metaphase, M for the middle of the cell". This is to remind you that at metaphase the centromeres of the chromosomes are aligned in the plane of the equator.
What is is the difference between metaphase 1 and 2?
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
Homologous chromosomes pair and undergo crossing over during?
Paired homologous chromosomes are found at the spindle equator during metaphase. During metaphase the chromosomes line up on the plate and attach to the fully formed spindle.
When do chromosomes align on a metaphase plate?
pair of tetrads facing opposite poles
During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
Stage when chromosomes align in one plane?
Mitosis is the process of cell division which involves 5 different phases. These phases include prophase, prometaphase, metaphase, anaphase and telophase. Metaphase is the phase in which the chromosomes line up in the middle of the cell.
