Eventually cells need to duplicate. There are two main methods of replication, mitosis and meiosis. This tutorial will talk about mitosis. The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.
The chromosomes.
Translocations
The DNA doubles during the S phase of interphase, which occurs before mitosis begins. In this phase, each chromosome is replicated, resulting in two sister chromatids for each chromosome. Mitosis itself consists of several stages—prophase, metaphase, anaphase, and telophase—but the actual doubling of DNA happens prior to these stages.
translocation
The process in which DNA duplicates itself is called DNA replication. This process is an important factor in biological inheritance.
Cellular reproduction, specifically mitosis, is the process by which a single cell divides to produce two genetically identical daughter cells, each containing the same number of chromosomes as the original cell. During this process, the cell's nucleus duplicates itself, ensuring that each new cell receives an exact copy of the genetic material. Mitosis is crucial for growth, repair, and maintenance in multicellular organisms. It typically involves several stages: prophase, metaphase, anaphase, and telophase, followed by cytokinesis, which divides the cytoplasm.
duplicate or replicate
A chromosome that lacks a partner and in which destroys or deletes itself.
Interphase
will replicate itself during the synthesis phase within its life cycle
Well in eukaryotic cells each chromosome has a telomere on each end (to prevent it from unraveling), but I'm not 100% certain that these telomeres are identical although they contain very long repetitions of the same nucleotides. But in bacteria the chromosome is ring shaped and is all genes (there are no noncoding sequences, e.g. centromeres, telomeres, introns, pseudogenes, transposons) so there are no identical parts.
