WebAug 17, 2024 · Because DNA has already replicated, each chromosome actually consists of two identical copies. The two copies of a chromosome are called sister chromatids. Sister chromatids are joined together at a region called a centromere. Figure 11.3. 2: Chromosome. After DNA replicates, it forms X-shaped chromosomes like the one … WebProphase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they...
WebAug 15, 2024 · As chromosomes are copied in preparation for production of a new cell, the centromere serves as an attachment site for the two halves of each replicated chromosome, known as sister chromatids. … Webthe period of the cell cycle at which the duplicated chromosomes are separated into identical nuclei; includes prophase, prometaphase, metaphase, anaphase, and telophase mitotic phase the period of the cell cycle when duplicated chromosomes are distributed into two nuclei and the cytoplasmic contents are divided; includes mitosis and cytokinesis
WebWhen the chromosomes maneuver to the center of the cell, metaphase begins (Fig. 5). The spindle fiber network connects the centromere of the replicated chromosome to the outer part of each cell. The chromosomes now resemble the line of scrimmage of a football team, poised and waiting for some cellular signal to begin the next phase. Figure 5. Weba) GAP 1 = G1 Phase = cell growth, RNA and protein synthesis this is the longest phase of the cycle. b) Synthesis = S Phase = DNA replication c) Gap 2 = G2 Phase = Replication …
