Cell cycle, the ordered sequence of events that occur in a cell in preparation for cell division. The cell cycle is a four-stage process in which the cell increases in size, copies its DNA, prepares to divide, and divides. Learn more about the cell cycle
当细胞质积累到一定量时,细胞分裂成两个子细胞,新生的子细胞长大后,又分裂成两个子细胞,细胞分裂成两个子细胞所需的时间称为细胞周期。细胞周期又包括分裂期(mototic stage)和分裂间期(interphase)
See how flow cytometry, immunofluorescence or immunohistochemistry can be used to easily determine the cell cycle status.
Understand the cell cycle phases. See descriptions of each stage of mitosis and understand what happens during interphase. Learn the importance of...
If 100 cells are examined, the number of cells in each identifiable cell cycle stage will give an estimate of the time it takes for the cell to complete that stage. Problem Statement: Given the events included in all of interphase and those that take place in each stage of mitosis, ...
A. Interphase B. Prophase C. Metaphase D. Anaphase 相关知识点: 试题来源: 解析 A。细胞周期中,间期负责 DNA 复制。间期包括 G1 期、S 期和 G2 期,其中 S 期进行 DNA 复制。前期(B 选项)主要是染色体出现等变化。中期(C 选项)染色体排列在赤道板上。后期(D 选项)姐妹染色单体分离。反馈...
Interphase 1.6.U4 Interphase is a very active phase of thecell cyclewith many processes occurring in the nucleus and cytoplasm. 间期是细胞周期中持续时间最长的时期,但是也视不同细胞类型而定,对生长很快的细胞来说,比如动物的胚胎或植物的根尖茎尖生长点(分生组织那块位置),间期大约24小时。对于不怎么分裂...
The mitotic cell cycle is divided into two distinct stages, interphase and M phase.The complex network of regulatory elements that form the cell cycle has one goal: the timely and accurate duplication and segregation of the genomic DNA.

The cell cycle (E-Fig. 1-18) consists of interphase (G1, S, and G2) and mitosis (M). Interphase, depending on the cell type, usually lasts at least 12 to 24 hours; in contrast, mitosis can be completed in as little as an hour or two. Cells enter the cell cycle in Gap 1 (...
