Discuss the roles of the following in protein synthesis in mammalian cells:- the large and small subunits of the ribosome, mRNA, tRNA, release factors, SRP. Genes drive metabolism, growth and differentiation in living cells. They do this by promoting the synthesis of proteins which in turn catalyse many biological reactions. Therefore the synthesis of proteins is one of the most central and basic events in the life of every cell. The process of proteins synthesis is divided into two different parts; transcription and translation. Transcription is performed by RNA polymerase which uses one strand of the DNA helix as a template to synthesis messenger RNA (mRNA). This mRNA then migrates from the nucleus to the cytoplasm. Translation then occurs and according to Lodish et al (1995) this process is when the base sequence of the mRNA is used to order and to join the amino acids in the protein. To explain...
