The nuclear membrane re-forms. Chromosomes line up in the center of the cell. DNA can be further packaged by forming coils of nucleosomes, called chromatin fibers. In contrast, telophase is where the chromosomes loosen to form chromatins. 2. b The chromosomes are V shaped. 7. Chromatin coils and condenses to form deeply-staining bodies in prophase. a.) Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromosomes are V-shaped c.) The nuclear envelope… Early prophase Chromatin condenses (coils up tightly) Chromosomes becomes (shorter and thicker) Late prophases Nuclear envelope disintegrates Nucleolus disappears Centrosomes move to opposite ends Spindle fibers form In prophase or metaphase 2 chromatids joined at the centromere Telophase Chromatids uncoils becoming chromatin The spindle breaks down A new nuclear envelope re-forms … The cell's chromatin condenses into chromosomes during prophase. These fibers are condensed into chromosomes … The chromosomes are V-shaped. Chromatin coils and condenses, forming chromosomes b.) Prophase (versus interphase) is the first true step of the mitotic process. 8. 2. Chromosomes stop moving toward the poles. 9. This is the first stage of mitosis, the process in which cells divide to create new cells. The mitotic spindle forms. During prophase, a number of important changes occur: 5. 3. e The nuclear envelope re-forms. Key: a. anaphase b. interphase c. metaphase d. prophase e. telophase 1. d Chromatin coils and condenses, forming chromosomes. While chromatin is permissive to DNA replication, RNA synthesis (transcription), and recombination events, the chromosomes are refractory to these processes as they are tightly coiled.. This is the first stage of mitosis, the process in which cells divide to create new cells. Explain the structure of chromosome? 3. chromatin: a complex of DNA, RNA, and proteins within the cell nucleus out of which chromosomes condense during cell division Eukaryotic Chromosomal Structure and Compaction If the DNA from all 46 chromosomes in a human cell nucleus was laid out end to end, it would measure approximately two meters. Presence. 6. Chromatin is located in the nucleus of our cells . The nuclear membrane fragments. It is made of DNA and a particular type of protein called Histones. 4. e Chromosomes stop moving toward the poles. DNA synthesis occurs. 6. d The nuclear envelope fragments. 10. Solution for What events happen in telophase? 5. c Chromosomes line up in the center of the cell. The nuclear envelope breaks down and spindles form at opposite poles of the cell. During a cell division this condenses to form chromosome. With 8 histones as the core, a DNA molecule winds around it forming a complex unit called nucleosomes. Centrioles replicate. Chromatin coils and condenses to form deeply-staining bodies in prophase. 4. 1. Chromatin coils and condenses, forming chromosomes. These units super coils together to form chromatin. In prophase, the chromatin condenses into discrete chromosomes. Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging.
