What stage are Chromosomes duplicated?
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
During which phase of the cell cycle are the chromosomes not individually visible?
Interphase, because during pro phase they become visible so that means in interphase they were not visible.
Why do you need to count chromosomes during mitosis?
It is possible to count chromosomes only during vell division (mitosis or meiosis). This is because when the cell is not dividing the chromosomes are in an uncoiled, extended state and are not visible under the microscope. During cell division the chromosomes coil up, becoming shorter and thicker and so visible. At this time they can be counted.
In which phase do chromosomes become visible?
The DNA of a cell condenses to form chromosomes during cell division or mitotis, called the M phase of the cell cycle. Specifically, chromosomes acquire their characteristic X shape in the metaphase stage of mitotis. Each chromosome consists of two sister chromatids joined at the centromere.
When are Chromosomes not visible?
In interphase the chromosomes are not yet visible but become visible in prophase

Are chromosomes visible during pro-phase?
yes they are now visible during prophase
During which phase of the cell cycle are the chromosomes not individually visible?
Interphase, because during pro phase they become visible so that means in interphase they were not visible.

Which phase do chromosomes first become visible?
Interphase as they become decondenced
When are Chromosomes not visible?
In interphase the chromosomes are not yet visible but become visible in prophase
Which phase of meiosis do diversification occur?
Diversification occurs during the crossing over phase of meiosis, which is Prophase I. During this phase, chromosomes exchange genetic material, resulting in the recombination of genetic material between homologous chromosomes. This process increases genetic diversity and contributes to the unique combination of traits in offspring.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
When Homologous chromosomes swap genetic information as part of meiosis?
Prophase I is the phase of meiosis.
What makes the chromosomes become visible during prophase?
When pro phase begins, the DNA molecules are progressively shortened and condensed by coiling, to form visible chromosomes.
The phase of mitosis during which chromosomes become visible and the centrioles seperate from one another is?
Prophase
