The process of protein modifications is typically completed in the Golgi apparatus of the cell. During this process, the proteins undergo various post-translational modifications, such as glycosylation, phosphorylation, and cleavage. These modifications are essential for the proper functioning and localization of the proteins within the cell.

Outline the outline the basic steps in making protein?
Transcription: The process where DNA is converted into mRNA. Translation: mRNA is used as a template for the synthesis of protein by ribosomes. Post-translational modifications: Addition of chemical groups or cleavage of amino acids to modify the protein's structure and function. Protein folding: The final step where the protein adopts its three-dimensional structure to become functional.
What are the most common post translational modifications?
Post-translation or Post-translational regulation refers to the control of the levels of active protein either by means of reversible events (Post-translational modifications, such as Phosphorylation or sequestration) or by means of irreversible events (proteolysis).
Which molecule completes the flow of information from DNA to protein?
The molecule that completes the flow of information from DNA to protein is messenger RNA (mRNA). mRNA carries the genetic information from DNA in the nucleus to the ribosomes in the cytoplasm where proteins are synthesized. The process by which mRNA is translated into a protein is called protein synthesis.
Is protein character ultimately determined by amino acid dietary adequacy?
Protein character is determined by the sequence of amino acids present in the protein, which is encoded by the DNA of an organism. While dietary adequacy of amino acids is important for protein synthesis, other factors such as post-translational modifications and protein folding also influence protein structure and function.
What is involved in the production of proteins?
Protein production involves transcription, where DNA is used as a template to make mRNA. This mRNA is then translated by ribosomes to assemble amino acids into a protein molecule according to the genetic code. Finally, the protein is folded into its functional form and may undergo post-translational modifications.
A researcher made an interesting observation about a protein used to build a cell's plasma membrane The final protein in the plasma membrane was slightly different from the protein made by the ER?
The observed difference between the final plasma membrane protein and the ER protein could be attributed to post-translational modifications. These modifications, such as glycosylation or phosphorylation, can alter the protein's structure and function during its journey through the cell to its final destination in the plasma membrane. This dynamic process allows cells to fine-tune protein function for specific roles in different cellular compartments.
What organelles participate in protein synthesis?
There are three organelles involved in protein synthesis. Golgi Apparatus, flattened membrane sacs and vesicles chemically modify protein. Rough Endoplastic Reticulum, contains a network of membranous sacs that bring synthesized proteins to the service. Ribosomes, which have two units, small and large, initializes and completes the protein synthesis.
What are the molecular linking steps from a gene to its final expression as a obvious phenotype?
The molecular linking steps from a gene to its final expression as a visible phenotype involve transcription of the gene into mRNA, translation of mRNA into protein, post-translational modifications of the protein, protein folding, protein trafficking to the correct cellular location, and protein-protein interactions to carry out its function. These processes are tightly regulated by various factors to ensure proper gene expression and phenotype manifestation.

Even when a gene is available and its sequence of nucleotides is known chemical studies of the protein are still required to determine what?
Chemical studies of the protein are required to determine its structure, function, and any post-translational modifications that may influence its activity. These studies help to understand how the gene's sequence of nucleotides translates into the final protein product and how it interacts with other molecules in the cell.
How would a protein be passed through the endomembrane system?
A protein enters the endomembrane system by being synthesized on ribosomes attached to the rough endoplasmic reticulum (ER). It then undergoes modifications and folding within the ER before being transported in vesicles to the Golgi apparatus. In the Golgi apparatus, further processing occurs before the protein is sorted and directed to its final destination within the cell.
What are final product of protein?
Proteins are the final product. They are made from amino acids.
What is conjugate protein?
Conjugated proteins are proteins that are covalently linked to other biomolecules such as lipids, carbohydrates, or prosthetic groups. These modifications can alter the structure, function, and localization of the protein in the cell.

Post-translation or Post-translational regulation refers to the control of the levels of active protein either by means of reversible events (Post-translational modifications, such as Phosphorylation or sequestration) or by means of irreversible events (proteolysis).

How many amino acids completes protein?
The term "complete protein" refers to amino acids, the building blocks of protein. A protein must contain all nine of these essential amino acids in roughly equal amounts.
What is the final product of recombinant DNA technology?
Typically a protein.
