What else can I help you with?
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.
What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
Cells produced at the end of telophase II have as many chromosomes as cells that started the process.?
Yes, cells produced at the end of telophase II have the same number of chromosomes as the cells that started the process. This is because during telophase II of meiosis, the chromosomes have already undergone segregation and have been divided equally between the daughter cells.
What is the name of division in eukaryote cells?
Cell division in eukaryotic cells involves mitosis, which is the division of the replicated chromosomes into two identical sets, and cytokinesis, which is the division of the cytoplasm.
Do cells replicate or copy their DNA before going through meiosis?
Yes. The DNA is replicated during interphase before prophase I.
What process are blood cells replicated?
mitosis
What would happen if cells with mutated DNA replicated?
Cancer.
Why is it essential that DNA be replicated?
The cells that follow must be the same as the cells that they came from. You don't want a finger to grow out of your nose.
What is a characteristic of mitosis and not of meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
In which organelle are chromosomes replicated?
Chromosomes are replicated in the nucleus of a cell. A nucleus is a membrane-enclosed organelle found in eukaryotic cells. It contains most of the cell's genetic material.
Where are mitochondria constructed?
They are not built. They replicate themselves in cells
What would happen if cells with mutated DNA replicated uncontrollably?
If cells with mutated DNA replicated uncontrollably, it could lead to the development of cancer. This is because the mutations can cause the cells to grow and divide rapidly, forming tumors that can invade nearby tissues and spread to other parts of the body.
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.
Why are all cells produced by mitosis exactly alike?
Becuase the DNA is replicated, so the two cells produced by mitosis are clones of eachother!
What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
How a cells chromosome change as a cell prepares to divide?
the chromosomes are replicated (copied) and are compacted into dense visible structures
Imagine looking through a microscope at a squashed onion root tip The chromosomes of many of the cells are plainly visible In some cells replicated chromosomes are aligned along the center equato?
You are likely observing cells in metaphase of mitosis, where replicated chromosomes are aligned along the center of the cell. This stage is essential for ensuring that each daughter cell receives the correct number of chromosomes. The presence of visible chromosomes indicates an active process of cell division.
