5 days ago · The endoplasmic reticulum (ER) is a compartment (organelle) in eukaryotic cells that consists of membrane sacs called cisternae. Because of the bound ribosomes, the 'rough' ER is the site of...
5 days ago · Both WS genes encode transmembrane endoplasmic reticulum (ER) proteins 5 and it is widely acknowledged that the primary defect in WS lies also in the ER 8,9,10,11. However, recent discoveries ...
3 days ago · An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
2 days ago · e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
3 days ago · Definition. A cell is the basic building block of living things. All cells can be sorted into one of two groups: eukaryotes and prokaryotes. A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not.
2 days ago · Science is a strict systematic discipline that builds and organizes knowledge in the form of testable hypotheses and predictions about the world.
3 days ago · A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.
