WebThe G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated. The G2 phase stands for gap 2 and is when DNA is proofread and DNA damage is repaired. The M phase is mitosis, which is further broken down into prophase, metaphase, anaphase, telophase, and cytokinesis. WebIt occurs in three main stages: initiation, elongation, and termination. Recall that eukaryotic DNA is bound to proteins known as histones to form structures called nucleosomes. …

WebForms the phosphodiester bonds between the nucleotides. State the role of a gene. A code for polypeptides. Explain how the structure of DNA allows replication. (5) it is a double helix strand. both strands act as a template. contains weak hydrogen bonds that can be easily broken. there are complementary base pairings: the purines and pyrimidines. WebAt what point does DNA replication occur and why? The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. chills meaning in telugu

"WebDuring mitosis the sister chromatids separate and go to opposite ends of the dividing cell. Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm). " - During which stage does dna replicate

Explanation: There are two broad sections of the cell cycle, interpase and mitosis. Interphase is divided into G1,S and G2. Mitosis is divided into prophase, metaphase, anaphase, and telophase. G1: "gap one". cell growth. S: "synthesis". DNA replication

WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...

WebReplication occurs before cell division, during the S phase of the cell cycle. However, replication only concerns the production of new DNA strands, not of new cells.
