Channel proteins are proteins that enable the transportation of certain substances and materials across cell membranes. Channel proteins consist of a wide group of more than 20 different organic compounds and, although they share the umbrella title of channel proteins, these substances play different roles. Channel proteins are formed in long chains of amino acids; the sequence of these chains dictates the function and shape of each channel protein.Know More
Bobcats, or Lynx rufus, are endemic to the North American continent. Highly adaptable, these animals thrive in forests, swamps, deserts, agricultural areas and sometimes even in suburban areas. It is estimated that there are 725,000 to 1,020,000 bobcats in the wild. Its name is based on the appearance of its tail, which looks cut or "bobbed."
Bobcats are rarely seen because they are mostly active at night. As strict carnivores, these fierce hunters prey on rabbits, birds, mice, squirrels and other smaller animals. Once they have spotted their prey, they calculate its exact location, and then leap as long as 10 feet to pounce on top of it to pin it down.Learn more about Molecular Biology & DNA
The most important polymers located within the nucleus of a cell are proteins and DNA molecules. Proteins exist as enzymes and structural components of a cell, and DNA functions as the blueprint for cellular reproduction processes that transfer hereditary information from cell to cell.Full Answer >
Transcribed RNA is separated from a single strand of DNA it used as a template, then cut into pieces to be translated into proteins, while DNA that forms during DNA replication remains bound to the single strand to become a new, full DNA molecule with a double strand. RNA transcription and DNA replication begin in very similar ways.Full Answer >
The Golgi apparatus collects simple chemicals in the cell and assembles them into large, complex structures such as proteins. It also plays a role in the process of simple chemical secretion by forming closed vesicles around the substance to be transported. These vesicles then pinch off from the Golgi apparatus and drift to the cell's plasma membrane where the transported substance is released from the cell.Full Answer >
"Noncoding" refers to a strand of DNA that does not contain the information that the body needs to create proteins. DNA contains a coding strand and a noncoding strand. The two strands are mirror images of each other, but only the coding strand has the information for making proteins.Full Answer >
