Which mRNA condon usually signals the beginning of protein synthesis?
Methionine is always the first amino acid in a protein, therefore the codon for Met would signal the beginning of protein synthesis. This codon is AUG.
Can amino acid be used more than once in protein?
yes mostly amino acid are used to synthesize the amino acid but also other can be found from glcolysis
Any what can be used by the body for the synthesis of a nonessential amino acid except?
An essential mineral
What organic compounds and cellular organelles are involved in protein synthesis?
Um, pretty much all the compounds involved in protein synthesis are organic. All the biochemistry of protein synthesis is carbon-based. So, I am going to assume that you are interested in how peptide or protein synthesis is done on the lab bench not in the cell. Is that right? If you take amino acids and want to make a polymer of them, the process is: 1. First you need to protect the the carboxyl group on amino acid 2 from reacting by adding something to make an ester, like CH3OH/HCl 2.And, you need to protect the amino group on amino acid 1 from reacting by adding di-tert-butyl dicarbonate (a.k.a. Boc). 3. Mix the two protected amino acids in the presence of DCC (dicyclohexyldiimide). This reagent couples the carboxylic acid from amino acid 1 to the unprotected amine on amino acid 2 to make an amide. 4.Add aqueous NaOH to remove the the protecting group on the carboxyl terminus. 5. If you are done, you can add a weak acid to remove the BOC protecting group from the amino end. If not, keep it there and do another peptide addition.

A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?
for mRNA, it takes 3 bases (A codon) to signal that a specific amino acid should be used. In this case you would need 100x3 = 300 bases.
What is the specific term that refers to an amino acid whose lack inhibits protein synthesis?
The amino acid synthesis inhibitors is a term used to describe amino acids that lack inhibits protein synthesis. These inhibitors include the sulfonylureas, imidazolinones, and amino acid derivatives herbicide families
What kinds of molecules contain the instructions for ordering amino acids in proteins?
what kind of molecules contain the insructions for ordering amino acid in protein
Which mRNA condon usually signals the beginning of protein synthesis?
Methionine is always the first amino acid in a protein, therefore the codon for Met would signal the beginning of protein synthesis. This codon is AUG.
What is the limiting amino acid factor?
This is where certain amino acids may not be used for its intended purpose due to depletion or used for other reasons. For example, the BCAA Leucine is great for protein synthesis after an intense workout, but when used as an energy source during workout, it becomes depleted which than restricts the protein formation for post-workout. This is the reason why more protein is needed, not just for growth and recovery, but to also compensate for the loss of the essential amino acids like BCAA Leucine when they are used for energy.
What molecules bring in the amino acids that are used in protein synthesis?
Transfer RNA.
WHat molecule is the monomer used to build protein?
amino acids
What is the subunit used to make protein?
Amino acid
Can amino acid be used more than once in protein?
yes mostly amino acid are used to synthesize the amino acid but also other can be found from glcolysis
Which process is used to release insulin from pancreatic cells into the bloodstream?
Exocytosis is the process used to release insulin from pancreatic cells into the bloodstream.
Any what can be used by the body for the synthesis of a nonessential amino acid except?
An essential mineral
How is a codon involved in protein synthesis?
A protein is made up of a bunch of Amino Acids.Codons are used as a code for tRNA which bind to them and each tRNA has bound to the other side if it an Amino Acid, So when there tRNAs bind to the codons they all bring Amino acids which get linked together by peptide bonds and form proteins.
Where does surplus amino acids broken?
The primary uses of amino acids are as building blocks for protein and peptide synthesis and as a source of nitrogen for the synthesis of other amino acids. Amino acids considered to be "surplus" will be catabolized meaning surplus amino acids are used as metabolic fuel.
