Protein synthesis is the creation of proteins. In biological systems, it is carried out inside the cell. In prokaryotes, it occurs in the cytoplasm. In eukaryotes, it initially occurs in the nucleus to create a transcript (mRNA) of the coding region of the DNA.

Who synthesis the protein?
Protein synthesis occurs in the cytoplasm on ribonucleoprotein particles, the ribosomes.
What carries out 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.
How do you synthesis a protein?
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.
Where does protein synthesis begin?
Protein synthesis, also called translation , begins when the two ribosomal subunits link onto the mRNA. This step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer RNAs (tRNAs).
Where are ribosomes found?
Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria.
What is translation process in protein synthesis?
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). ... Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.
How are proteins synthesized in the lab?
Protein synthesis is a two-step process that involves two main events called transcription and translation. In transcription, the DNA code is transcribed (copied) into mRNA. ... However, DNA is not directly involved in the translation process, instead mRNA is transcribed into a sequence of amino acids.
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.
Where does protein synthesis start in the cell and end?
Protein synthesis is the creation of proteins. In biological systems, it is carried out inside the cell. In prokaryotes, it occurs in the cytoplasm. In eukaryotes, it initially occurs in the nucleus to create a transcript (mRNA) of the coding region of the DNA.
What is the first part of protein synthesis?
In the first step, transcription, the DNA code is converted into a RNA code. A molecule of messenger RNA that is complementary to a specific gene is synthesized in a process similar to DNA replication. The molecule of mRNA provides the code to synthesize a protein.
Does protein synthesis occur in the Golgi apparatus?
The Golgi apparatus is a major collection and dispatch station of protein products received from the endoplasmic reticulum (ER). Proteins synthesized in the ER are packaged into vesicles, which then fuse with the Golgi apparatus. ... The Golgi apparatus is also involved in lipid transport and lysosome formation.
What is lysosome function?
Lysosomes are membrane-bound organelles with roles in processes involved in degrading and recycling cellular waste, cellular signalling and energy metabolism. Defects in genes encoding lysosomal proteins cause lysosomal storage disorders, in which enzyme replacement therapy has proved successful.
Who discovered lysosomes?
Christian de Duve, whose laboratory in Louvain discovered lysosomes in 1955 and defined peroxisomes in 1965, died at his home in Nethen, Belgium at the age of 95, on May 4, 2013.
Who discovered mitochondria?
Mitochondria, often referred to as the “powerhouses of the cell”, were first discovered in 1857 by physiologist Albert von Kolliker, and later coined “bioblasts” (life germs) by Richard Altman in 1886. The organelles were then renamed “mitochondria” by Carl Benda twelve years later.
