How is anaphase I of meiosis different than anaphase of mitosis?
In anaphase for both types of cell division, the centromeres of each chromosome separates and the spindle fibers pull apart the sister chromosomes. In mitosis, this is the shortest phase of cell division.However, the differences between mitosis and meiosis are different. Because meiosis is when chromosomes are "mixed and matched" in order to make new different combinations, the strands are only mixed up so when they split, they have new genes at their ends. Because mitosis is when chromosomes are duplicated, or cloned, and are copies of each other, when they split, the new cell is the exact same copy as the original.
Why is duplication of chromosome required before mitosis?
Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.
Meiosis is different from prophase of mitosis in every chromosomes pairs with its what?
In meiosis, during prophase I, each chromosome pairs with its homologous chromosome to form a structure known as a tetrad. This pairing allows for the exchange of genetic material through a process called crossing over, which increases genetic diversity. In contrast, during prophase of mitosis, chromosomes do not pair with homologous chromosomes; instead, they align independently without genetic exchange. This key difference is crucial for the distinct outcomes of meiosis and mitosis.
Many cells in your body grow and divide every every day by what process?
Mitosis.
How many bases does a single human chromosome contain?
Every chromosome is a different size so the number of base pairs is different for each chromosome. X chromosome has more that 153 million base pairs (greater that 306 million bases) Y chromosome has around 50 million base pairs (around 100 million bases)
How many DNA strands constitute a chromosome?
every and any DNA strand can constitue to a chromosome :)
Where are chromosomes genes and DNA located?
Chromosomes are genetic information condensed from chromatin during cellular division. Chromatin is located within the nucleus of a cell, but during either mitosis or meiosis, chromosomes are formed and enter the dividing cell before reaching the equatorial plate where they are torn apart to separate daughter cells by the spindle apparatus.
Is mitosis taking place in us?
Every second of every day of your life
Why must a cell chromosome duplicate before mitosis occurs?
Chromosome duplication ensures that each daughter cell receives a complete set of genetic information. This process also helps to maintain the proper chromosome number in the daughter cells after cell division. Duplicate chromosomes allow for accurate segregation of genetic material during mitosis, ensuring that each daughter cell receives a copy of every chromosome.
What does every cell in every living thing come from another cell that?
has undergone mitosis
How did every cell in your body originate?
through the process of mitosis.
What cell has two of every kind of chromosome?
