Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
The solenoid structure's most obvious function is to help package the DNA so that it is small enough to fit into the nucleus. This is a big task as the nucleus of a mammalian cell has a diameter of approximately 6 μm, whilst the DNA in one human cell would stretch to just over 2 metres long if it were unwound. [6]
The phosphorylation of YAP serves to export it from the nucleus and prevent it from activating growth-promoting genes; this is how the Hippo-YAP pathway inhibits cell growth. [10] More importantly, the Hippo-YAP pathway uses upstream elements to act in response to cell-cell contact and controls density-dependent inhibition of proliferation.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Systematic evolution of ligands by exponential enrichment (SELEX), also referred to as in vitro selection or in vitro evolution, is a combinatorial chemistry technique in molecular biology for producing oligonucleotides of either single-stranded DNA or RNA that specifically bind to a target ligand or ligands.
The top 10 once again looks a little different in the new US LBM Coaches Poll after Week 12. The shuffling, however, didn’t reach the apex of the rankings. The shuffling, however, didn’t reach ...
Two decades since the first eukaryotes were sequenced, the "biological role" of around 20% of proteins are still unknown. [10] Many of these proteins are conserved across most eukaryotic species and some are conserved in bacteria, indicating a role fundamental for life.
AFGE, the country's largest labor union for federal employees, is fighting back against Republican criticisms that government workers are abusing remote work policies.
