What is the 2nd stage of protein synthesis?
Translation. Translation is the second part of protein synthesis. Once transcription and the following processing are complete, translation is initiated. This is where the newly created mRNA’s genetic code is read and used to produce proteins.
What are the names of the 2 processes of protein synthesis?
Protein synthesis can be divided broadly into two phases – transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA).
What are the 3 stages of protein synthesis?
We can separate the process of protein synthesis into three distinct steps. Initiation, elongation, and termination.
What are the 5 steps of protein synthesis in order?

- (a) Activation of amino acids:
- (b) Transfer of amino acid to tRNA:
- (c) Initiation of polypeptide chain:
- (d) Chain Termination:

Where does the 2nd step of protein synthesis occur?
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 triggers protein synthesis?
Protein ingestion and resistance exercise both stimulate the process of new muscle protein synthesis (MPS) and are synergistic when protein consumption follows exercise. In healthy persons, changes in MPS are much greater in their influence over net muscle gain than changes in muscle protein breakdown (MPB).
What happens in initiation of protein synthesis?
During initiation, the small ribosomal subunit binds to the start of the mRNA sequence. Then a transfer RNA (tRNA) molecule carrying the amino acid methionine binds to what is called the start codon of the mRNA sequence. The start codon in all mRNA molecules has the sequence AUG and codes for methionine.
What is the purpose of protein synthesis?
The purpose of protein synthesis is simply to create a polypeptide — a protein made out of a chain of amino acids. In a hair follicle cell, a protein called keratin is made. Lots of it. Many ribosomes can be working on a single strand of mRNA at once.
What is the process of protein synthesis in order?
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.
What is the chronological order for protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
What are the first and second steps of protein synthesis?
In the first step, called transcription, the genetic code in DNA is copied by RNA. In the second step, called translation, the genetic code in RNA is read to make a protein.
