How are proteins made and what do they do? The Proteome: The proteome is the full complement of proteins in a given type of cell or tissue under specific conditions. The proteome, unlike the genome, is dynamic, responsive to environmental conditions and cues from other cells, and expansive ...

Nuts, beans and soybeans are all high in protein. By combining them, you can get complete coverage of all essential amino acids. The digestive system breaks all proteins down into their amino acids so that they can enter the bloodstream. Cells then use the amino acids as building blocks to...
What are proteins? How can diversity of proteins in living organisms be explained? What is the function of a protein? A) What enzymatic reaction does glucokinase perform in metabolism? How does it differ from other hexokinases, and why is this important in pancreatic Beta cells? B) Explain ...
Think about this, while proteins are migrating through the polyacrylamide matrix, the leading edge is encountering smaller pore sizes than the lagging edge. That means that the leading edge is passing through the gel at a slightly slower pace compared to the lagging edge. So, the band sort of...
melanogaster to create flies that carry clones of cells in which all H3 proteins are mutated at Lys27. These cells show upregulation of PcG targets, which demonstrates that H3K27 is essential for PcG-mediated silencing. CAS PubMed Google Scholar Muller, J. Transcriptional silencing by the ...
"Proteins are in essence tiny machines that perform different jobs inliving organisms. These machines require that their parts move in a specific way to accomplish specific tasks, like for example, a drum of a washing machine needs to be able to rotate with a specific speed to wash the cloth...
Millions of genetic fragments derived from LINE-1 are found in our cells. The vast majority are inactive evolutionary relics, evidence of failed attempts to hijack the replication machinery. But about 100 LINE-1s are operational—and usually not helpful. One protein produced by LINE-1, known as...
Replacing months of experiments with a few hours of computing time could shed new light on the inner workings of cells. It could speed up drug development. And it could in particular suggest treatments for diseases like Alzheimer’s, in which misshapen proteins are thought to play a role. arc...
