The viral component that is responsible for inducing a host cell to take in an influenza virus by endocytosis would be hemagglutinin. It is a glycoprotein that can be found in the surfaces of an influenza virus and is essential to its entry to hosts. It is the substance that is responsible for allowing the virus to bind to cells especially cells in the respiratory tract. It also causes the RBC or the red blood cells to agglutinate or clump together. The hemagglutinin is cylindrical in shape and is 13.5 nm in length. It has 18 different antigens wherein they are named H1 to H18.
The correct answers are:
2) Peptide bonds form from nucleophilic attack by an electron pair on an alpha - amino nitrogen atom on an alpha - carboxyl carbon atom of another amino acid and
4) Peptides are polymers of amino acids.
A peptide bond is an amide type of covalent chemical bond. It is formed between two amino acids: C1 (carbon end) of one alpha-amino acid and N2 (nitrogen end) of another. Peptide bonds are the basis for the formation of a peptide chain and consequently protein. Formation of peptide bond is a condensation process, meaning that when two amino acids combine and link, water molecule is released and dipeptide is a product of that reaction.
