The site of protein synthesis in the cell is primarily the ribosome, a cellular structure composed of both RNA and protein. The ribosome plays a central role in reading the messenger RNA (mRNA) sequence and translating it into a specific string of amino acids, which then grow into long chains that fold to form proteins . This process occurs in the cytoplasm of both prokaryotic and eukaryotic cells, where ribosomes serve as the key sites for protein synthesis
Ribosomes and Protein Synthesis
Location: Ribosomes can be found as free structures in the cytoplasm or attached to the rough endoplasmic reticulum (RER), where they participate in protein synthesis
Function: The ribosome's large subunit has three active sites called E, P, and A sites, which are crucial in the catalytic activity of ribosomes during protein synthesis
.
Types of Ribosomes: There are two types of ribosomes: 70S ribosomes bmk glycidate in prokaryotes and 80S ribosomes in eukaryotes, each made up of two subunits of differing sizes.
Role in Protein Biosynthesis
Transcription and Translation: The process of protein biosynthesis involves transcription, where a section of DNA encoding a protein is converted into mRNA, and translation, where the mRNA is translated into a specific order of amino acids at the ribosomes, forming a functional protein
Initiation, Elongation, and Termination: Protein synthesis can be divided into three phases: initiation, elongation, and termination, all of which occur at the ribosome
