In eukaryotic cells, the ribosomes either occur freely in the cytoplasm or remain attached to the outer surface of the membrane of the endoplasmic reticulum. The location of the ribosomes in a cell determines what kind of protein it makes. If the ribosomes are floating freely throughout the ...
The second type of RNA istransfer RNA(tRNA). This is a smaller nucleic acid molecule and comes in 20 subtypes, one for each amino acid. Its purpose it to shuttle its "assigned" amino acid to the site of translation on the ribosome so that it can be added to the growing polypeptide (...
The ribosomes attached to the RER receive the messengers carrying the transcribed code and use that information to make a chain of specificamino acids. This step is called **translation** because the ribosomes read the data code on the messenger and use it to decide the order of the amino...
The nucleus is a site for transcription in which messenger RNA (mRNA) are produced for protein synthesis. During the cell division, chromatins are arranged into chromosomes in the nucleus. Production of ribosomes (protein factories) in the nucleolus. ...
docking site on the endoplasmic reticulum. Following this, the elongating polypeptide is discharged through the membrane into the intracisternal space. Virtually all of the lysosomal enzymes are glycoproteins. Core glycosylation occurs during translation but final processing occurs in the cis Go...
