Sister Chromatids Diagram Quizlet
Sister chromatids are attached to each other from the time DNA is duplicated till anaphase, through the action of proteins called cohesins. Initially, cohesins are present along the entire length of the chromosome, especially around heterochromatin regions. Therefore, at prophase, sister … See more Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the … See more Diploid organisms have two copies of every chromosome, one received from each parent through their gametes. These pairs are called homologous chromosomes and … See more During the congression of chromosomes at the metaphase plate, when some kinetochores are unattached to the spindle, an active signal inhibits the onset of anaphase. This involves the Mitotic Checkpoint Complex … See more DNA duplication during S phase of the cell cycle allows cells to maintain their genetic content across generations. The primary function of sister … See more WebSister chromatids line up at the metaphase plate. The nucleus re-forms and the cell divides. The kinetochore becomes attached to metaphase plate. Sister chromatids line up at the metaphase plate. The kinetochore … WebThe diagram below shows homologous chromosome during phase 1 of meiosis.
