What determines the different shapes and functions of proteins?
A protein's structure is determined by:- the amino acid sequences of its polypeptide chains;- hydrogen bonds between amino acids in polypeptides;- other bonds (e.g. hydrophobic interactions, disulphide bridges) between side chains in the polypeptides; and- the arrangement of polypeptides (in a protein that contains more than one polypeptide)Scientists have mapped the structures of several proteins; however, scientists are still unsure as to how proteins actually form their final structures.The function of a protein is directly related to its structure. For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.
Where do the amino acids that are carried by the tRNA come from?
it comes from the food that you eat every day. Food's protein is large so it has to use enzyme to break down from polymer chain into monomer to fit to the "gate" to go inside the cytoplasm of the cell.
What purpose for amino acid?
Amino acids are the building blocks of proteins in the body. They have several important functions, including building and repairing tissues, supporting immune function, and producing enzymes and hormones. Amino acids are also used as a source of energy when needed.
What is the role of nitrogen in the production of proteins?
Nitrogen is an essential component of proteins as it is present in the amino acids that make up proteins. During protein synthesis, nitrogen is incorporated into the structure of amino acids through various biochemical reactions, ultimately leading to the formation of complex protein molecules.
Does every codon represent an amino acid?
No, not every codon represents an amino acid. There are several codons known as "stop" codons (UGA, UAA, UAG) that do not code for an amino acid; instead they code for the termination of translation.
What what amino begins every protein chain?
Aug which is the codon for methanine
What amino acid is at the end of every protein chain?
valine
What amino begins every proteins chain?
Aug which is the codon for methanine
How many amino acids will be in the first amino acid in every growing polypeptide?
The first amino acid in a growing polypeptide chain is usually methionine when translation initiates in eukaryotes, and formylmethionine in prokaryotes. Therefore, there will be one amino acid in the first position of every growing polypeptide chain.
What amino acid does every newly translated protein begin with?
In eukaryotes, every newly-translated protein begins with the amino acid methionine (Met, M). This is because the start codon that signals the beginning of translation is AUG, which is also the codon for methionine - so the correlation is obligatory. The methionine may be removed during post-translational processing/modification.In prokaryotes, however, every newly-translated protein begins with formylmethionine (fMet), a methionine derivative with a formyl group added to the amino group. This difference can be used as a target for antibiotic therapy. As with methionine, the formylmethionine can be removed after translation.
What living thing begins every food chain?
Producers are living things that begin every food chain.
How does the order of the nitrogenous bases determine the type of protein that will be produced?
Every 3 bases specifies either an amino acid or a terminator. The amino acid sequence creates the protein. The terminator ends the protein.
How do variations in DNA reflects changes in an organism protein?
every amino acid is difined by a set of 3 baces. If you change the amino acids you change the protien.
What proteins are found in amino acids?
Proteins, large and complex biomolecules, are made of amino acids. The amino acids react together to form longer chains called polypeptides. The so-called primary structure of a protein is determined by the specific amino acid sequence unique to every protein, whereas its secondary structure depends on how the polypeptide chain is coiled. The tertiary structure of a protein is finally how the protein looks in 3D. And if several polypeptides interact, forming an even bigger structure, then the protein is said to have a quaternary structure. There are essential and non-essential amino acids. The non-essential ones are made in the body, whereas the essential amino acids must be found in the diet.

Nutrients that keep you muscles strong?
Amino acids are the building blocks of life, so protein blends contain many of the essential amino acids needed for muscle growth. I would recommend drinking a protein shake every day.
What does amino acids break down?
The newly formed (nascent) protein [amino acid] chain - as it exits the Ribosome Protein Bio-Assembly Miracle - is directed to either the exterior of the endoplasmic reticulum - also known as The Cytoplasm - or to the interior of the endoplasmic reticulum. As it is extensively known that there are several types of {cytoplasmically periferal} ER, there are sequences of the nascent protein chain, called leader sequences, that direct the nascent proteins to their Cytoplasmic ER destination, - where either the leader sequence will be removed and the remaining protein segment activated, or a portion only of it is removed and the location process continues as above until the protein reaches it's Bio-desired active location. When the protein reaches its destination its processing is completed and it is folded into its natural three dimensional conformation. Further Aggregation may and often does occur.
