During metaphase can evidence of chromosome duplicaion now be observed?

During metaphase, chromosomes are aligned at the cell's equatorial plane, and each chromosome is composed of two sister chromatids, which are the result of DNA replication that occurred during the S phase of interphase. This duplication is evident as each chromosome appears as a distinct X-shaped structure. The sister chromatids are still attached at a region called the centromere, making it clear that chromosome duplication has taken place prior to metaphase. Thus, while the physical separation of chromatids occurs later during anaphase, the evidence of duplication is clearly observable during metaphase.


During what part of the mitosis process does the DAN replicate?

DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.


What stage of mitosis does replication happen in?

Replication does not take place during mitosis. It takes place before meiosis begins.


In what stage of the cell cycle do independent chromosomes duplicate?

Independent chromosome duplication occurs during the S (synthesis) phase of the cell cycle. This is when DNA replication takes place, resulting in two identical sister chromatids attached at the centromere.


What happens in the s phase that is essential for mitosis to occur?

In the S phase of the cell cycle, DNA replication takes place, resulting in the synthesis of identical copies of each chromosome. This is essential for mitosis to occur because each daughter cell needs to receive a complete set of chromosomes. Without the S phase, there would not be enough genetic material to distribute to the daughter cells during mitosis.

Duplication of the nuclear material takes place during what phase?

interphase


What must occur with the DNA in the original cells in order for mitosis to make new cells?

DNA replication must occur in the original cells before mitosis can take place. This ensures that each new cell receives a complete set of genetic information. During mitosis, the replicated DNA is separated and distributed to the new daughter cells.

If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?

the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes


In which of the stages does each chromosome consist of two DNA molecules?

(From the end of the S phase of interphase through the metaphase of mitosis). In eukaryotes, throughout the entire life of the Cell, also called the cell cycle. During Mitosis the chromosomes are separated.

What will happen to chromosomes that has two centromere?

centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.


What phase is the period of interphase when genetic information is being duplicated?

The S phase of the cell cycle (mid-interphase).There are 4 main phases. The "S phase" of the cell cycle is when the cell duplicates the genetic information, or DNA. * G1 = growth and preparation of the chromosomes for replication * S = synthesis of DNA by semi-conservative replication and duplication of the chromosome * G2 = preparation for mitosis * M = mitosis


What happens during prophase you that does not happen during mitosis?

During prophase in meiosis, homologous chromosomes pair up and undergo crossing over, exchanging genetic material. This process does not occur during mitosis, where individual chromosomes line up and separate without crossing over.


DNA is copied in which stage of the cell cycle?

DNA is replicated during the Synthesis (S) phase of cell growth. This comes after G1 and before G2. Mitosis follows G2.
