What else can I help you with?
What is one of the two strands of a chromosome that become visible during meiosis or mitosis?
One of the two strands of a chromosome that becomes visible during meiosis or mitosis is known as the chromatid. Each chromatid is an exact copy of the other, formed during DNA replication in the interphase preceding cell division.
What is one of the two strands of a chromosomes that become visible during meiosis or mitosis?
daughter strands
When choromosomes are visible in the nucleus?
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.
When cell chromosome become visible what are the duplicate strands of DNA called?
Daughter Chromosomes
How many chromatids are present in a chromosome t the beginning of mitosis?
Two chromatids are present in a chromosome at the beginning of mitosis.
When two nuclei are visible this is what phase?
When two nuclei are visible, it is typically during metaphase of mitosis. In metaphase, the chromosomes align at the center of the cell, and the nuclear membrane has disintegrated, allowing the nuclear material to be clearly visible.
What are chromosomeswhere and when they are visible in the cell?
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
When can you see chromosomes under light microscope?
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.
What happenes in prophase?
the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
How many chromosomes are are visible at the beginning of mitosis?
At the beginning of mitosis, each chromosome is duplicated and consists of two identical sister chromatids joined together. Therefore, the number of visible chromosomes at the start of mitosis is equal to the number of unique chromosomes in the cell. This number varies depending on the organism, but for humans, there are 46 visible chromosomes at the beginning of mitosis.
