What is the the mitosis stage when the chromatids are visible?
It is during the prophase when chromatids become visible. Prophase is the first as well as the longest stage of mitosis.
During anaphase of meiosis do the chromosomes have one or two chromatids as they move toward the poles?
During the anaphase stage of mitosis the two chromatids become separate chromosomes. The chromatids are pulled apart and move toward their centrosomes. As they move toward the poles, the centrosomes go first, followed by the chromatids, forming a â??vâ?? shape.
When does a chromosome first become visible in mitosis?
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
What two things happen during Metaphase?
During metaphase - the second stage of mitosis in the eukaryotic cell cycle - the chromosomes, pulled by the spindle fibers, line up along the middle of the cell, halfway between the centrosomes in the middle of the dividing cell. The chromosomes are now maximally condensed. In mitosis, individual replicated chromosomes, each composed of two sister chromatids, move to the equatorial plate during this step (whereas during the first division of meiosis, pairs of replicated chromosomes (tetrads) line up at this stage). This lack of pairing between homologs during mitosis is a fundamental distinction between mitosis and meiosis. Mitosis, unlike meiosis, produces identical daughter cells, because each homolog divides into two identical chromatids during anaphase.
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.

Chromosomes first become visible during which phase of mitosis?
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.

How does the appearance of the chromosome change through division?
first it becomes two chromatids, then during prophase, chromosomes condense from long strands into rod like structures. During METAPHASE paired chromatids align at the cell's equation. Then during ANAPHASE the paired chromatids separate and move to the opposite side of the cell. During TELOPHASE a nuclear membrane forms around each set of chromosomes, and the chromosomes decondense.
What phase do sister chromatids form?
The sister chromatids first appear in the S phase of the cell cycle.
During which phase of the cell do sister chromatids first appear?
S phase
How many chromatids does each chromosome have after S-phase?
A chromatid really only exists during the first two stages of mitosis(prophase and metaphase). This is when the DNA has been replicated and the chromosomes essentially is composed of 2 identical segments.
What is duplicated during the process of mitosis?
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
What are the three stages of the cell cycle of a eukaryotic cell?
First stage - The cell grows and copies its organelles and chromosomes. During this time, the strands of DNA and proteins are like loosely coiled pieces of thread. After each chromosome is duplicated, the two copies are called chromatids. Chromatids are held together at a region called the centromere. The chromatids each twist and coil and condense into an X shape. After this happens, the cell enters the second stage of the cell cycle. Second Stage - The chromatids separate. The complicated process of chromosone is separation is mitosis. Mitosis ensures that each new cell receives a copy of each chromosomes. Mitosis can be divided into four phases. Third Stage - The cell divides and produces two cells that are identical to the original cell. Cell division will be discussed after mitosis has been described.
