Web17 de dez. de 2016 · Interphase Definition. Interphase is the longest stage in the eukaryote cell cycle. During interphase, the cell acquires nutrients, creates and uses proteins and other molecules, and starts the process of cell division by replicating the DNA. Interphase is divided into three distinct stages, Gap 1, Synthesis, and Gap 2, which are discussed below. WebG 1 Phase (First Gap). The first stage of interphase is called the G 1 phase (first gap) because, from a microscopic aspect, little change is visible. However, during the G 1 stage, the cell is quite active at the biochemical level. The cell is accumulating the building blocks of chromosomal DNA and the associated proteins as well as accumulating sufficient …
