WebDuring the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the ... WebViewing Chromosomes Chromosomes generally are not visible as distinct entities in nondividing cells, since the DNA is uncoiled, but the process of mitosis is facilitated by supercoilingof the chromosomes into a highly compacted form.

WebChromosomes become visible during prophase. A more accurate answer says that the chromosomes are visible during late prophase, which is sometimes called prometaphase. See eNotes Ad-Free... WebChromosomes condense and become visible by light microscopy as eukaryotic cells enter mitosis or meiosis. During interphase (G1 + S + G2), chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes). In G1, each chromosome is a single chromatid. how to style long turtleneck sweater

WebThe distinctly visible chromosome arrange themselves at the equatorial or metaphasic plate. The centromeres lie at the equational plate while the limbs are placed variously according to their size and spiral arrangement. At prophase the chromosomes appear thin and filamentous, forming a network. So they are not very clearly visible. WebIn prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers. In the next phase, metaphase, the chromosomes line up along the metaphase plate. The spindle fibers are completely formed and are attached to each sister chromatid of the chromosomes. WebChromosome is one that has a centrally located centromere and chromosome arms with approximately equal length. Submetacentric Chromosomes have centromeres located close to the center of the chromosome, but the chromosome arms are distinctly unequal in length Acrocentric reading hands on activities
