How does the chromosome duplicate itself

WebThis occurs by undergoing DNA replication (in S phase during interphase) where the monovalent chromosome is duplicated so that it will have two DNA strands that are replicas of each other. These two strands are each now called a sister chromatid, and the two sister chromatids make up a divalent chromosome. Webhow are they different? a. Mitosis—a process through which DNA can duplicate itself b. Process through which gametes are formed. Halves the number of chromosomes normally present in body cells. c. Mitosis duplicates the DNA and meiosis halves the chromosomes. gametes sex cells. the sperm and the ovumn define zygote

WebIn the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase). WebThe cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis.
