Where are chromatids found in a cell?
nucleus
The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA.
Where are chromatids located during telophase?
9th grade p-ap biology
| Question | Answer |
|---|---|
| Where are chromatids located during telophase | Opposite poles |
| What disassembles in telophase? | Spindle |
| What reforms around each set of sister chromatids during telophase? | Nuclear envelope |
| What organelle reappears inside the nucleus? | Nucleolus |
Where are the chromatids during metaphase?
equator
During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers. During anaphase, sister chromatids are separated at the centromere and are pulled towards opposite poles of the cell by the mitotic spindle.
What does S phase stand for?
Synthesis
The S stage stands for “Synthesis”. This is the stage when DNA replication occurs.
Can a chromatid be a chromosome?
Then during mitosis, when the DNA is transferred to the two daughter cells, one of each of those chromatids is transferred to each of the two cells. So a chromatid is one copy of a chromosome after DNA replication.
Where is the M checkpoint?
The M checkpoint occurs near the end of the metaphase stage of mitosis. The M checkpoint is also known as the spindle checkpoint because it determines whether all the sister chromatids are correctly attached to the spindle microtubules.
Why does the cell get longer during anaphase?
Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell. Microtubules not attached to chromosomes elongate and push apart, separating the poles and making the cell longer.
What can happen if cells do not duplicate correctly?
If cells don’t replicate their DNA or don’t do it completely, the daughter cell will end up with no DNA or only part of the DNA. This cell will likely die. Cells also copy their DNA right before a special cell division event called meiosis, which results in special cells called gametes (also known as eggs and sperm.)
What phase is 92 chromatids?
anaphase
During metaphase, there are 46 chromosomes composed of two sister chromatids each that align at the metaphase plate. Then, during anaphase, these chromatids are separated and pulled to opposite poles of the cell. This separation results in 92 separate chromatids in the cell, which are considered 92 chromosomes.
What happen during the S phase?
S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end.
What is another name for the S phase?
S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
How many DNA is in a chromosome?
2
One chromosome has 2 strands of DNA in a double helix. But the 2 DNA strands in chromosomes are very, very long. One strand of DNA can be very short – much shorter than even a small chromosome. Strands of DNA are made by joining together the 4 DNA bases in strings.
