What happens in meiosis during anaphase1?
During anaphase I of meiosis, homologous chromosomes are pulled apart and moved towards opposite poles of the cell. This separation occurs as the spindle fibers shorten, pulling each homologous chromosome, which consists of two sister chromatids, away from its partner. Unlike in mitosis, where sister chromatids separate, meiosis I involves the segregation of entire homologous chromosomes, reducing the chromosome number by half. This stage is crucial for creating genetic diversity, as it contributes to the random assortment of chromosomes.
What happens when plates separate from each other?
Ridges, called spreading centers, happen where two plates move away from each other. As the plates separate, molten mantle material (magma/melted rock) flows up to fill the void.
In which phase do chromosomes become visible?
The DNA of a cell condenses to form chromosomes during cell division or mitotis, called the M phase of the cell cycle. Specifically, chromosomes acquire their characteristic X shape in the metaphase stage of mitotis. Each chromosome consists of two sister chromatids joined at the centromere.
What does anaphase mean?
During mitosis, each chromosome is made up of two clones, known as chromatids. These chromatids are joined together and look like two halves of an X. Anaphase is the period of mitosis when these chromatids separate at the middle and begin to move apart from each other. By separating the identical DNA halves, two new cells can be formed with the same genetic material as the original.
How close are all the planets to earth?
Venus our sister planet is about 36,000,000 miles away from us mars is about 1 inch away from us.
What happens during the segregation of chromosomes?
Homologous chromosomes pairs pull away from each other.
What is the function of mircotubules during anaphase?
During anaphase, microtubules help to separate sister chromatids by attaching to the kinetochores and pulling them towards opposite poles of the cell. This movement ensures that each daughter cell receives a complete set of chromosomes.

What phase will homologous chromosomes move away from each other?
Homologous chromosomes move away from each other during anaphase I of meiosis, which is when the spindle fibers pull the homologous chromosomes to opposite poles of the cell. This separation allows each daughter cell to receive a complete set of chromosomes.
In what phase of mitosis do the sister chromatids move to opposite poles of the cell?
In the third stage, anaphase, the sister chromatids ofeach replicated chromosome begin to separate.Fibers pull the centromere apart and chromatidsmove away from each other, toward opposite ends of thecell.
Briefly describe what happens during anaphase?
In anaphase, the paired chromosomes (sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell. At the end of anaphase, each pole contains a complete compilation of chromosomes.The paired centromeres in each distinct chromosome begin to move apart.Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Do you have to separate a pregnant guinea pigs from other animals?
It is advised to separate any pregnant animals away from other animals, so yes.
How does the alignment of chromosomes differ at the equator between metaphase of mitosis and metaphase of meiosis 1?
In prophase the membrane of nucleus disappears, then the nucleus too, chromosomes unwrap, collocation of spindle apparatus is completed. In metaphase: chromosomes line up on equatorial cell-plate. there is very little difference
How do you separate a horse with its pasture mate?
no hard fealings just move them away from each other
What phase of mitosis do sister chromatids line up in the center of the cell?
This phase is called the metaphase. Remember' M' for middle and 'M' for metaphase. In the next phase (anaphase) the chromosomes move away from each other: remember 'A' for away. Telophase is the last or 'terminal' phase: remember 'T' for terminal. Prophase occurs prior to (ie before) the other phases: remember 'P' for prior. Interphase is in between cells divisions: remember 'I' for in between. Clear answer is metaphase.
What to do if your sister is too addicted with your dog?
i think you should try to get your dog away from your sister,ex:My sister is ADDICTED to my cat,i sometimes make my sister go away from my cat. i hope this helped.
Can the custodial parent put the child in a separate home away from the rest of the family?
Yes, if it's the home of the other parent.
