Which of the following are features of proteins? -they are generally circular molecules. -they are made up of 20 different amino acids. -their synthesis involves the participation of several distinct types of RNA molecule. -unlike DNA, protein never forms a helical structure. -during protein synthesis, the growing chains are extended at the N-terminus More than one answer can be right I am confused please help
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.
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
