Chromosome duplication occurs for the beginning of which process? select all that apply.

The image shows the process of mitosis. The replication of DNA happens at prophase of the mitosis process. This results in the duplication of the chromosomes This is followed by the segregation and division of the duplicated chromosomes into the two daughter cells. The same applies to the meiosis process where the DNA replication and duplication are followed in the same manner as mitosis. Hence the duplication of chromosomes happen at the beginning of both mitosis and meiosis processes.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
