 Protein Biosynthesis Protein biosynthesis is the process through which biological cells build new proteins and is balanced by loss of cellular proteins through export or degradation. Translation which is protein assembly by ribosomes plays an important role in the pathway of biosynthetic along with messenger RNA generation (mRNA), post-translational modification, co-translational transport and aminoacylation of
