What evidence shows mitosis is a continuous process not a series of separate events?
What evidence shows mitosis is a continuous process, not a series of separate events? Them movement and placement of the chromosomes. Procedure: In science, we observed mitosis.
What evidence supports mitosis is a continuous process?
What evidence shows that mitosis is a continuous process? Because all cells change at different times and not all at the same time, it shows that mitosis is a multi-step continuous process. Also, because the cycle keeps repeating, it is a continuous process that does not end. A single cell has X number of chromosomes.
Is cell division continuous or does it occur in separate steps?
Although cell growth is usually a continuous process, DNA is synthesized during only one phase of the cell cycle, and the replicated chromosomes are then distributed to daughter nuclei by a complex series of events preceding cell division.
Why is the cell cycle a continuous process?
In adults, cell divisions are involved in renewing old tissues rather than growth. Therefore millions of cells undergo continuous replacement at the same time in our body. Complete answer: Cell division is known to be a process through which a parent cell divides.
Is mitosis is a continuous process?
While the process of mitosis is continuous process within the cell cycle (i.e., it doesn’t occur in discrete steps), biologists are classifiers and tend to place things into discrete categories. Mitosis is commonly divided into four major phases: prophase, metaphase, anaphase, and telophase.
Which phase of mitosis is longest?
The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down.
Which is not a step in mitosis?
The correct answer is option B because interphase is another phase of the cell cycle where DNA is duplicated in preparation for mitosis.
What stage comes after mitosis?
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
Is mitosis the longest phase of the cell cycle?
In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. … At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
What happens in the stages of mitosis?
During mitosis, when the nucleus divides, the two chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. Mitosis occurs in four phases: prophase, metaphase, anaphase, and telophase.
Which type of cells divide by mitosis?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
Which statement does not describe cell cycle checkpoints?
Which statement DOES NOT describe cell cycle checkpoints? Defective checkpoints results in death of the cell. Which statement is not True for DNA? What kind of cells most likely result from uncontrolled growth due to mutations in genes that control the cell cycle?
Is mitosis a continuous process or a series of separate events?
Although mitosis is a continuous process, chromosomal movements and other cytological changes allow it to be arbitrarily divided into a series of subphases known as prophase, prometaphase, metaphase, anaphase, and telophase (Fig.
Which process is continuous throughout the cell cycle?
Cell division is a continuous process.
What is the continuous process of cell division repair and growth?
Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by meiotic cell division from gametes. After growth, cell division by mitosis allows for continual construction and repair of the organism.
