WebThe ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis. WebTranslation efficiency has been traditionally used as a measure of how efficiently proteins are synthesized from a specific transcript. It is defined as the rate of protein synthesis from a single copy of a mRNA transcript. However, since the production of a ribosome consumes much more cellular resources than an mRNA molecule, a better resource ...
