WebbIn 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. WebbFig. 6.18. Protein digestion in the stomach. Because of the hydrochloric acid in the stomach, it has a very low pH of 1.5-3.5. The acidity of the stomach causes food proteins to denature, unfolding their three-dimensional structure to reveal just the polypeptide chain. This is the first step of chemical digestion of proteins.

After synthesis and modifications, protein irreversibly segregate inside the lumen of the ER. Soon after translation, the formation of multi-subunit protein occurs known as oligomerization. A molecular chaperone (BiP) binds to the nascent protein and prevents them from folding inappropriately. shopzhub.com

WebbIf the protein is going to be used within the cytoplasm of the cell, the ribosome creating the protein will be free-floating in the cytoplasm. If the protein is going to be targeted to the lysosome, become a component of the plasma membrane, or be secreted outside of the cell, the protein will be synthesized by a ribosome located on the rough endoplasmic … WebbDescribe the process of protein synthesis (6 marks) EDIT: So, I have come up with this response (Feel free to critique / improve or tell me your comments on it): Firstly, the DNA is transcripted into mRNA which acts as a messenger molecule to get the code from the DNA onto the ribosomes, this is done because the DNA itself is too big to leave ...

Webb21 aug. 2024 · Mariana Ruiz Villarreal/Wikimedia Commons. Protein synthesis is accomplished through a process called translation. After DNA is transcribed into a messenger RNA (mRNA) molecule during transcription, the mRNA must be translated to produce a protein. In translation, mRNA along with transfer RNA (tRNA) and ribosomes … WebbSteps of protein synthesis process: There are 5 major steps of the protein synthesis process are: Activation of amino acids. Transfer of amino acids to tRNA. Initiation of the polypeptide chain. Chain termination and. Translocation of the protein molecule.
