What happens to DNA in anaphase?
The homologous chromosomes (as pairs of sister chromatids) separate to opposite poles of the cell.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
What happens after chromosomes condense?
After chromosomes condense during cell division, they align along the center of the cell during metaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, during telophase and cytokinesis, the cell divides into two daughter cells, each with a complete set of chromosomes.
What is true of both galvanic and electrolytic?
reduction happens at the cathode Oxidation happens at the anode
What happens during anaphase 1and 2?
Anaphase 1: 1. Breakdown of proteins responsible for sister chromatid cohesion along chromatid arms allows homologs to separate. 2. The homologs move toward opposite poles, guided by the spindle apparatus. 3. Sister chromatid cohesion persists at the centromere, causing chromatids to move as a unit towards the same pole. At anaphase 1 of meiosis, the replicated chromosomes of each homologous pair move toward opposite poles, but the sister chromatids of each replicated chromosome remain attached. In anaphase of mitosis, by contrast, sister chromatids separate. Reference Cambell et al. Biology (8th Ed) 2008. Benjamin Cummings. pg 254-257
What happens in telophase II?
Sister Chromatids separate from each other just like mitosis .
What happens to DNA in anaphase?
The homologous chromosomes (as pairs of sister chromatids) separate to opposite poles of the cell.
What happens during anaphase?
The chromatids are pulled apart.
What happens to sister chromatids in meiosis?
During meiosis, sister chromatids separate during anaphase II, resulting in four haploid daughter cells with different genetic material. This process ensures genetic variation in the offspring.
Nondisjunction happens in?
It is the failure of chromosome pairs to separate properly during cell division.
How does the appearance of the chromosome change through division?
During cell division, chromosomes condense and become more visible under a microscope as they coil up tightly. The chromosomes then line up along the center of the cell before being pulled apart into two separate sets. Finally, the chromosomes decondense back into chromatin after division is complete.
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What happens to the amount of chromosomes during cell division?
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
What happens in the anaphase?
Telophase and then Cytokinesis occurs, where the cells are being split into two.
What happens in a cell during anaphase?
During anaphase, the sister chromatids are pulled apart to opposite ends of the cell by spindle fibers. This ensures that each daughter cell receives a complete set of chromosomes during cell division. The cell membrane may also start to constrict in preparation for cytokinesis.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
What happens directly after prophase?
Metaphase
