NettetMetaphase in cells (here an animal cell) are characterized by the arrangement of chromosomes at the equatorial plane of the spindle Chromosomes lined up on the metaphase plate. Two views with the … NettetMeiosis I: Meiosis I is the first division, the reduction division, of meiosis. There are 4 sub-phases in meiosis I: • Prophase I: During prophase I, homologous chromosomes line up side by side. They are physically in contact with one another. This process is known as synapsis. Synapsis is when crossing over occurs.

NettetIn metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes. NettetIn metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II , the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II , nuclear membranes form around each set of chromosomes, and … Get AI Guide Donate Login Sign up. Search for courses, skills, and videos.

NettetChromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell , ready to divide. NettetThe sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. Chromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase. NettetIn meiosis I, the homologous chromosome pairs become associated with each other, are bound together with the synaptonemal complex, develop chiasmata and undergo crossover between sister chromatids, and line … buy schmitten chocolate online
