Physically speaking, DNA is a long string of paired chemical units (nucleotides) that come in four different types, abbreviated A, T, C, and G, and it carries information organized into units called genes. Genes typically provide instructions for making proteins, which give cells and organisms their functional characteristics.

Jul 31, 2022During DNA duplication in the S phase, each chromosome is replicated to produce two identical copies, called sister chromatids, that are held together at the centromere. The centrosomes, which are the structures that organize the microtubules of the meiotic spindle, also replicate. This prepares the cell to enter prophase I, the first meiotic

Each replicated chromosome consists of two sister chromatids. Chromosome centromeres serve as a place of attachment for spindle fibers during cell division. Metaphase: Chromatin becomes even more condensed and sister chromatids line up along the mid-region of the cell or the metaphase plate. Anaphase: Sister chromatids are separated and pulled

The role of mitosis in the cell cycle is to replicate the genetic material in an existing cell—known as the “parent cell”—and distribute that genetic material to two new cells, known as “daughter cells.” In order to pass its genetic material to the two new daughter cells, a parent cell must undergo cell division, or mitosis.
genetics – The human has 46 double chromosomes or simple chromosomes? – Biology Stack Exchange
A cell spends most of its life in interphase, which has three phases: G1, S, and G2. In the G1 phase, the cell grows and takes in nutrients. In the S phase, the cell’s DNA is replicated. Each replicated chromosome consists of two sister chromatids connected at the centromere. The G2 phase is another growth phase, after which the cell is ready
