In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.

Proteins perform important functions in organisms. In fact, this class of molecules is found in every cell and is essential for life. Here are some examples of functions performed by proteins: 1. form the scaffolding that maintains cell shape 2. catalyze metabolic reactions 3. essential in animal diets as a source of certain amino acids 4. transpor...
A protein may consist of a single polypeptide or multiple polypeptide subunits. Some proteins include non-peptide groups, called cofactors. A cofactor may be an organic group (e.g., coenzyme, prosthetic group) or an inorganic group (e.g., metal ion or iron-sulfur cluster). Each polypeptide is a linear molecule made from a string of amino acids that...
Proteins are common in everyday life. Most of the structure of organs and tissues consist of proteins. Here are some examples: 1. keratin 2. actin 3. myosin 4. hemoglobin 5. collagen 6. elastin 7. albumin 8. fibrin 9. insulin 10. immunoglobulins (antibodies) 11. catalase (and all enzymes)

Apr 7, 2019 · Translation refers to the process of creating proteins from an mRNA template. The sequence of nucleotides on the RNA is translated into the amino acid sequence of proteins and this reaction is carried out by ribosomes.
Oct 9, 2024 · Translation, the synthesis of protein from RNA. Translation takes place on ribosomes, where messenger RNA molecules are read and translated into amino acid chains. These chains are then folded in various ways to form proteins. Translation follows transcription, in which DNA is decoded into RNA.

The most common examples are the α-helix, β-sheet and turns. Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule. Tertiary structure: the overall shape of a

Feb 17, 2023 · The first step, called transcription, involves rewriting the information in DNA to mRNA. In contrast, the second step is called translation. Thus the main purpose of translation is to convert the information in mRNA into a particular sequence of amino acids (a polypeptide chain), forming a protein.
