What else can I help you with?
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.
One function of gel electrophoresis is to?
To separate strands of DNA based on their size. Shorter strands will migrate more slowly than larger strands. ** Also because DNA is slightly negatively charged, it will move toward the positive end of the electrodes... this is why the current is used when running a gel. Short strand move further** than large ones due to the gel resistance.
What phase do centromeres break and chromosomes begin migration toward opposite poles of the cell?
During anaphase of cell division, centromeres break apart and chromosomes begin their migration towards opposite poles of the cell. This is a crucial stage where sister chromatids separate and are pulled towards the poles by the mitotic spindle fibers.
Single sister chromatids are found in cells at mitotic?
Anaphase and telephase-Anaphase begins when the paired centromeres of each chromosome separate, liberating the sister chromatids, which begin moving toward opposite poles of the cell. At telophase, the chromosomes have reached the poles and daughter nuclei form.
What is the opposite of caudal?
The opposite of caudal (toward the tail) is cephalad (toward the head).
What is anaphase 2?
The centromeres of each chromosome finally separate, and the sister chromatids come apart. The sister chromatids of each chromosome now move as two individual chromosomes toward opposite poles.
Which specific structure must separate during anaphase in order for sister chromatids to begin moving toward opposite poles?
During anaphase, the centromere must separate for sister chromatids to start moving towards opposite poles. This separation allows each chromatid to be pulled to the poles by the spindle fibers attached to the centromere.
What phase does replicated strands move toward opposite poles?
During anaphase of mitosis or anaphase II of meiosis, the replicated DNA strands move toward opposite poles of the cell. This happens after the sister chromatids are separated and pulled apart by the spindle fibers.
What stage of mitosis the cromatids separate and move toward opposite poles?
During anaphase of mitosis, the chromatids separate and move toward opposite poles of the cell. This occurs when the cohesin proteins holding the sister chromatids together are cleaved, allowing them to be pulled apart by the spindle fibers. As a result, each chromatid is now considered an individual chromosome, ensuring that each daughter cell will receive an identical set of chromosomes.
What does across mean?
Across means "to, toward, or from the far side of", "on the opposite side of", or "spanning two separate objects".
What is opposite of caudal?
The opposite of caudal (toward the tail) is cephalad (toward the head).
Sister chromatids separate and a pulled to opposite poles by the mitotic spindle?
During mitosis, sister chromatids, which are identical copies of a chromosome, separate during anaphase. The mitotic spindle, composed of microtubules, attaches to the centromeres of the chromatids and pulls them toward opposite poles of the cell. This separation ensures that each daughter cell receives an identical set of chromosomes, maintaining genetic consistency. Proper functioning of the spindle is crucial for accurate cell division and the prevention of genetic disorders.
What is the opposite word of from?
The opposite of from would be to, or toward.
What word is opposite of from?
The opposite of from would be to, or toward.
Which stage of meiosis do chromatids separate and become daughter chromosomes?
Chromatids separate and become daughter chromosomes during anaphase II of meiosis. In this stage, the sister chromatids, which were previously aligned at the metaphase plate, are pulled apart by spindle fibers and move toward opposite poles of the cell. This separation reduces the chromosome number in the daughter cells, leading to the formation of gametes. Following this, the cells will undergo cytokinesis to complete the process.
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.
What is the third stage of the chromosomes separate?
The third stage of chromosome separation occurs during anaphase of mitosis or meiosis. In this phase, sister chromatids are pulled apart toward opposite poles of the cell by the spindle fibers, ensuring that each new daughter cell will receive an identical set of chromosomes. This separation is crucial for maintaining genetic stability during cell division.
