What is the structure and function of protein synthesis?
Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.
What is the function in protein synthesis?
Protein synthesis represents the major route of disposal of amino acids. Amino acids are activated by binding to specific molecules of transfer RNA and assembled by ribosomes into a sequence that has been specified by messenger RNA, which in turn has been transcribed from the DNA template.
What are the components of protein synthesis?
Protein synthesis is the creation of proteins by cells that uses DNA, RNA, and various enzymes. It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis.
What is the structure and function of proteins?
Proteins fold up into specific shapes according to the sequence of amino acids in the polymer, and the protein function is directly related to the resulting 3D structure. Proteins may also interact with each other or other macromolecules in the body to create complex assemblies.
What are the basic steps of protein synthesis?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Who perform the function of protein synthesis?
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
What are the 5 steps of protein synthesis?
Terms in this set (5)
- Unzipping. – DNA double helix unwinds to expose a sequence of nitrogenous bases.
- Transcription. A copy of one of the DNA strand is made.
- Translation (Initiation) mRNA couples w/ ribosome & tRNA brings free amino acids to ribosomes.
- Elongation. – Anticodon of tRNA recognizes codon on mRNA.
- Termination.

What are the structures that synthesize proteins?
Proteins are synthesized at ribosomes. Some of these are attached to the endoplasmic reticulum (ER) forming what is called the rough ER. As proteins are synthesized the growing chain then is often inserted into the sacs of the rough endoplasmic reticulum. Jun 11 2019
What is the cell structure that is synthesize protein?
Protein Synthesis Proteins are synthesized in the body through a process called translation. Translation occurs in the cytoplasm and involves the rendering of genetic codes that are assembled during DNA transcription into proteins. Cell structures called ribosomes help translate these genetic codes into polypeptide chains.
What’s the entire process of protein synthesis?
Overall, the process of protein synthesis involves transcription of DNA to mRNA , which is then translated into proteins. This process requires proper coordination of RNA, DNA, enzymes, and ribosomes. The stepwise procedure of protein synthesis is also known as ‘central dogma’ in molecular biology.
What organelle is responsable for protein and lipid synthesis?
The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.
