What best describes the events of anaphase?
Each homologous pair of sister chromatids migrates to opposite poles. Which of the following best describes the events of anaphase I of meiosis? The two pairs of sister chromatids migrate to the same pole. Each homologous pair of sister chromatids migrates to opposite poles.
What separates during the anaphase phase of mitosis quizlet?
(B) In anaphase of mitosis, homologous chromosomes separate, but in anaphase I of meiosis, sister chromatids separate. (C) Sister chromatids do not separate in mitosis, but in anaphase I of meiosis, sister chromosomes do separate.
What happens during prophase metaphase anaphase and telophase?
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister …
Which of the following is the best description of the events occurring during anaphase I of meiosis?
Which of the following is the best description of the events of anaphase I? Homologous chromosomes randomly separate and migrate to opposite poles. Which of the following occurs during prophase?
What major events occur during anaphase of mitosis?
What major events occur during anaphase of mitosis? The sister chromatids of replicated chromosomes separate, and the spindle poles are pushed farther apart. Identify the events in the cell cycle that must be completed successfully for daughter cells to share an identical complement of chromosomes.
Which of the following best describes what occurs during metaphase?
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. … As metaphase continues, the cells partition into the two daughter cells.
What happens during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. … Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
What is the activity of the cell during anaphase mitosis cell division?
During anaphase A, the cohesins that bind sister chromatids together are cleaved, forming two identical daughter chromosomes. Shortening of the kinetochore microtubules pulls the newly formed daughter chromosomes to opposite ends of the cell.
How does anaphase I in meiosis differ from anaphase in mitosis?
In anaphase 1 in meiosis, homologous pairs are separated but sister chromatids stay joined together. In anaphase 1 of mitosis the sister chromatids do separate.
