- Protein synthesis steps are twofold. Firstly, the code for a protein (a chain of amino acids in a specific order) must be copied from the genetic information contained within a cell’s DNA. This initial protein synthesis step is known as transcription.

Jul 18, 2020 · The transcription process is the first step of protein synthesis. This step transfers genetic information from DNA to the ribosomes of the cytoplasm or rough endoplasmic reticulum. Transcription is divided into three phases: initiation, elongation and termination.
Feb 17, 2023 · The process of protein synthesis occurs in two steps: transcription and translation. In the first step, DNA is used as a template to make a messenger RNA molecule (mRNA). The mRNA thus formed, exits the nucleus through a nuclear pore and travels to the ribosome for the next step, translation.
In the first of the two stages of making protein from DNA, a gene on the DNA molecule is transcribed into a complementary mRNA molecule. Stage 1: Initiation. A region at the beginning of the gene called a promoter—a particular sequence of nucleotides—triggers the start of transcription. Stage 2: Elongation.

However, the translation of mRNA is only the first step in the formation of a functional protein. The polypeptide chain must then fold into the appropriate three-dimensional conformation and, frequently, undergo various processing steps before being converted to its active form.

Protein synthesis begins with the formation of an initiation complex. In E. coli , this complex involves the small 30S ribosome, the mRNA template, three initiation factors (IFs; IF-1, IF-2, and IF-3), and a special initiator tRNA , called tRNA Metf .
Jul 30, 2022 · In the first of the two stages of making protein from DNA, a gene on the DNA molecule is transcribed into a complementary mRNA molecule. Stage 1: Initiation A region at the beginning of the gene called a promoter —a particular sequence of nucleotides—triggers the start of transcription.
The initiation of protein synthesis is the process that results in bringing together an 80S ribosome with a messenger RNA (mRNA) and initiator methionyl-transfer RNA (Met-tRNA i).
