Essays on Cell Cycle
Cell division and cell proliferation as well as cell death are the two major physiological processes that are used to regulate tissue homeostasis in the adult organism. Genome integrity, cell proliferation and survival are controlled by a network of pathways that include cell cycle checkpoints, DNA repair, DNA recombination and programmed cell death. Tissue homeostasis...
Nucleic acids are molecules made up of nucleotides that direct cellular activities such as cell division and protein synthesis. Each nucleotide is made up of a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acids: DNA and RNA. DNA carries the genetic blueprint of the cell and is...
No matter you are the microbe, plant or large animal, you all have cells. But what makes you like this, it is decided by the DNA information. That is to say, the DNA information inside the cells controls all the traits you have. Thus, we really need to understand how important DNA information is as...
1. Introduction The approval of Chinese hamster ovary (CHO) cell cultures for the manufacturing of protein therapeutic products modernized conventional medicine. CHO cells remained the workhorse for the production of monoclonal antibodies (mAbs) for the last at least 20 years for different reasons. First, CHO cells are easily adapting and growing in suspension cultures which...
Calcium (Ca2+) is a molecule that acts as an intracellular signal which regulates numerous cellular processes such as cell differentiation, proliferation, and apoptosis. Cell proliferation is an intricate procedure organised by numerous proteins related to Ca2+ signalling in different parts of the cell. In resting cells, the Ca2+ concentration in cytosol is fairly low –...
