What is the synthesis of proteins in a cell?
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.
Who is responsible for protein synthesis in a cell?
Ribosomes
Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
Where are proteins are synthesized?
ribosomes
Protein synthesis occurs in the cytoplasm on ribonucleoprotein particles, the ribosomes.
How are proteins synthesized?
The Art of Protein Synthesis During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.
Which element is used in the synthesis of proteins?
Nitrogen
Nitrogen is used in the synthesis of protein.
What is an example of protein synthesis?
When protein synthesis is taking place, enzymes link tRNA molecules to amino acids in a highly specific manner. For example, tRNA molecule X will link only to amino acid X; tRNA molecule Y will link only to amino acid Y. Messenger RNA is synthesized in the nucleus using the DNA molecules.
How does protein synthesis affects the cell?
Protein synthesis underpins much of cell growth and, consequently, cell multiplication. Understanding how proliferating cells commit and progress into the cell cycle requires knowing not only which proteins need to be synthesized, but also what determines their rate of synthesis during cell division.
Why do cells need protein synthesis?
Without them, our cells couldn’t do their jobs and we would die. Like the furniture in your house, proteins wear out over time, so our cells are continuously making new proteins through the process of protein synthesis. Protein synthesis has two main steps: transcription and translation.
What amino acid initiates protein synthesis?
Protein synthesis is initiated universally with the amino acid methionine. In Escherichia coli, studies with anticodon sequence mutants of the initiator methionine tRNA have shown that protein synthesis can be initiated with several other amino acids.
