INTERPHASE Meaning and
Definition
-
Interphase is a crucial phase within the cell cycle of eukaryotic cells, occurring between cell divisions. It is conventionally divided into three stages: G1 (gap phase 1), S (synthesis phase), and G2 (gap phase 2). Interphase serves as the period for cell growth, DNA replication, and preparation for subsequent cellular division.
During the G1 phase, cells undergo intense growth, both in size and in terms of the synthesis of proteins and organelles. This phase is essential for the cell to accumulate sufficient energy and molecular building blocks required for DNA replication. Following G1, the S phase commences, which is characterized by the replication of the cell's genetic material. Within the S phase, the cell's DNA undergoes duplication, resulting in the formation of identical sister chromatids held together by the centromere.
Subsequently, the G2 phase commences, during which the cell continues to grow and prepares itself for cell division. It involves protein synthesis and the production of additional organelles and molecules essential for the upcoming division. G2 phase serves as a checkpoint to ensure that all DNA has been replicated accurately and no damage or errors have occurred.
Overall, interphase acts as a vital interlude for cell growth, DNA replication, and overall preparation before progressing to the active phases of cell division (mitosis or meiosis). It is essential for proper cell functioning, ensuring the accurate transmission of genetic material and the maintenance of cellular homeostasis.
Common Misspellings for INTERPHASE
Etymology of INTERPHASE
The word "interphase" originates from the combination of two Latin roots: "inter", meaning "between", and "phasēs", meaning "phases" or "stages". The term is commonly used in biology to refer to the period between successive cell divisions, specifically in the context of the cell cycle.
