This video explains how mitosis helps all plants and animals grow and repair. The cell cycle is how a cell divides to make two genetically identical version through specific phases – synthesis, ...
A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.
CU Boulder News & Events: Cells use multiple mechanisms for cell-cycle arrest upon withdrawal of individual amino acids (Cell Reports 2023)
Amino acids are required for cell growth and proliferation, but it remains unclear when and how amino acid availability impinges on the proliferation-quiescence decision. Here, we used time-lapse ...

CU Boulder News & Events: Replication-dependent histone biosynthesis is coupled to cell-cycle commitment (PNAS 2021)
The current model of replication-dependent (RD) histone biosynthesis posits that RD histone gene expression is coupled to DNA replication, occurring only in S phase of the cell cycle once DNA ...
Cell publishes findings of unusual significance in any area of experimental biology, including but not limited to cell biology, molecular biology, neuroscience, immunology, virology and microbiology, cancer, human genetics, systems biology, signaling, and disease mechanisms and therapeutics.
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
