WebWhat are the different phases of a cell cycle: The different phases of a cell cycle include: Interphase – This phase includes the G1 phase, S phase and the G2 phase. M phase – This is the mitotic phase and is divided into prophase, metaphase, anaphase and telophase. Cytokinesis – In this phase the cytoplasm of the cell divides. WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the …

Cyclin is a family of proteins that controls the progression of a cell through the cell cycle by activating cyclin-dependent kinase (CDK) enzymes or group of enzymes required for synthesis of cell cycle. See more Cyclins were originally discovered by R. Timothy Hunt in 1982 while studying the cell cycle of sea urchins. In an interview for "The Life Scientific" (aired on 13/12/2011) hosted by Jim Al-Khalili See more Cyclins are generally very different from each other in primary structure, or amino acid sequence. However, all members of the cyclin family are similar in 100 amino acids that make up … See more In addition, the following human protein contains a cyclin domain: CNTD1 See more • Krieger M, Scott MP, Matsudaira PT, Lodish HF, Darnell JE, Zipursky L, Kaiser C, Berk A (2004).
