Choosing Bathroom Countertops. Vanity tops must play the dual role of being durable and capable of standing up to water, soap, cosmetics while serving as an ample work surface for morning rush hour in the bathroom. This is no place for delicate, porous (read: easy-to-stain) surfaces.
1 one set for those proteins synthesized by ribosomes that remain suspended in the cytosol, and. 2  a second set for proteins synthesized by ribosomes that are attached to the membranes of the endoplasmic reticulum (ER) forming rough endoplasmic reticulum (RER).
Proteins needed inside the nucleus are transported in through the nuclear pores. The nucleolus is usually visible as a dark spot in the nucleus, and is the location of ribosome formation. Ribosomes are where RNA is translated into protein. This process is called protein synthesis. Protein synthesis is very important to cells, therefore large numbers of ribosomes are found in cells. Ribosomes float freely in the cytoplasm, and are also bound to the endoplasmic reticulum (ER).
