8. hich of the following is polypeptides? O true about The peptide bond that links the amino acids together is a type of covalent bond formed through dehydration synthesis. ○ If the overall isoelectric charge of a polypeptide is negative, it will be pulled towards the cathode end during gel electrophoresis. The polypeptide chain modified with ubiquitin molecules are tagged for proteasomal degradation In prokaryotic translation, the initial polypeptide chain produced has a formylmethionine amino acid at the N- terminal.

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
