Multiple nucleotide/peptide

Multiple nucleotide/peptide/saccharide synthesis refers to the simultaneous (parallel) synthesis of a multitude of nucleotide/peptide/saccharide sequences, irrespective of the chain... 

The rate of protein synthesis is about 6 peptide bonds per minute, thus, it takes, about 1 to 2 minutes to synthesize an average sized protein. Because mRNA is often several thousand nucleotides in length, the same mRNA molecules can be simultaneously bound by many ribosomes. An mRNA that is bound by multiple ribosomes is called a polysome. Polysomes provide a mechanism for many copies of a protein to be translated from a single mRNA. Polysomes in the cytosol synthesize most of the proteins and enzymes required by the body for intracellular processes such as metabolism. 

Mechanisms Interferons are glycoproteins produced in human leukocytes (IFN-a), fibroblasts (IFN-(3), and immune cells (IFN-y)- They exert multiple actions that affect viral RNA and DNA synthesis. Interferons induce the formation of enzymes, including a protein kinase that phosphorylates a factor which blocks peptide chain initiation, a phosphodiesterase that degrades terminal nucleotides of tRNA. and enzymes that activate RNase.
