This is the biochemistry questions and answers section on protein synthesis with explanation for various interview, competitive examination and entrance test solved examples with detailed answer description, explanation are given and it would be easy to understand. 5 protein synthesis begins when mrna, ribosomes, gtp, initiation factors and fmet trna come together to form the _____ fmet trna sits in the ___ site and binds to the aug codon on mrna, leaving the ___ site open for the next activated trna to come into the initiation complex.
Site of protein synthesis
The nucleolus, ribosomes and protein synthesis professor alfred cuschieri department of anatomy, university of malta objectives state the main characteristics of messenger, ribosomal and transfer rna. Protein synthesis occurs in structures within cells known as ribosomes, which are found outside the nucleus it is one of the most important cell processes while the actual synthesis occurs outside.
The trna amino acid complex moves to the ribosomes, the site of protein synthesis activation of ribosome back to top it is the step in which the smaller and the larger subunits of ribosome are joined together this is brought about by mrna chain. Protein synthesis is the process whereby biological cells generate new proteins it is balanced by the loss of cellular proteins via degradation or export. Protein synthesis is one of the most important biological processes by which individual cells build specific proteins in order to function protein synthesis occurs in the rough endoplasmic reticulum, ribosomes and in the nucleus note that rough. Translation: the synthesis of protein the synthesis of proteins is known as translation translation generally occurs in the cytoplasm, where the ribosomes are located. Protein synthesis is a complex, multi-step process involving many enzymes as well as conformational alignment however, the majority of antibiotics that block bacterial protein synthesis interfere with the processes at the 30s subunit or 50s subunit of the 70s bacterial ribosome.

Hi rna acts as the information bridge between dna and protein mrna is the message that carries genetic information from the dna in the nucleus to the cytoplasm trna is the adaptor that reads the mrna and brings the amino acids to the ribosomes for protein synthesis.
