What is the function of 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..
Where did translation protein synthesis occur in the cell?
In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process transcription of DNA to RNA in the cell’s nucleus. The entire process is called gene expression.
What is the site of protein synthesis?
Protein is assembled inside cells by an organelle called a ribosome. Ribosomes are found in every major cell type and are the site of protein synthesis.
What are the four steps of protein synthesis?
Steps of TranscriptionInitiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. … Elongation is the addition of nucleotides to the mRNA strand.Termination is the ending of transcription. The mRNA strand is complete, and it detaches from DNA.
What is the first step of protein synthesis called?
TranscriptionProtein synthesis is the process used by the body to make proteins. The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA.
What are the two main 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.
What are the 4 steps of translation?
Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).
What are the three components needed for protein synthesis?
The three roles of RNA in protein synthesis. Messenger RNA (mRNA) is translated into protein by the joint action of transfer RNA (tRNA) and the ribosome, which is composed of numerous proteins and two major ribosomal RNA (rRNA) molecules. [Adapted from (more…) 1.
What are the 9 steps of protein synthesis?

Where does each step of protein synthesis occur?
protein synthesis occurs in cellular structures called ribosomes , found out-side the nucleus. The process by which genetic information is transferred from the nucleus to the ribosomes is called transcription. During transcription, a strand of ribonucleic acid (RNA) is synthesized.
Where does the second step of protein synthesis occur in the cell?
Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein.
What are the 5 steps in protein synthesis?

What is the last step of protein synthesis?
terminationAnswer and Explanation: The last step in protein synthesis is termination. During termination, the ribosome reads the stop codon in the mRNA.
