What is the linear chain of amino acids in a protein?
The monomers in a polypeptide are the amino acids. The sequence of amino acids in a polypeptide (or protein) is called the primary structure. It is the primary structure of proteins which is coded for by the DNA in the genes: the sequence of bases in the DNA is a code for the sequence of amino acids in a protein (or polypeptide).

If the sequence of bases in mRNA is UUU UUA AUU GUC CCA the sequence of amino acids in the polypeptide will be?
The sequence of amino acids in the polypeptide will be Phenylalanine-Leucine-Isoleucine-Valine-Proline. This is because each group of three mRNA bases (codon) corresponds to a specific amino acid, as determined by the genetic code.
How are codons used in polypeptide formation?
Four 'types' of nucleotide bases - when they are read three-at-a-time - this is considered to be a triplet-codon. Triplet codons are individually related to one specific amino acid, a polypeptide being a short protein.
If there are three amino acids how many bases would there be on the M RNA to make these three?
Each amino acid is encoded by a set of three nucleotide bases in mRNA, known as a codon. Therefore, to encode three amino acids, there would need to be a total of nine nucleotide bases in the mRNA (3 amino acids x 3 bases per amino acid = 9 bases).
How many codons are needed to specify three amino acids 6 or 9?
The answer is nine because one codon has 3 letters.Improved AnswerThe above answer is completely incorrect. The question is how many codons are necessary to specify three amino acids, not bases (letters). As my original answer (which was removed by the previouis contributor) pointed out, each amino acid requires one codon to specify it, so the basic answer is, three codons are necessary to specify any three amino acids. However, if the questioner had in mind how many codons are necessary to specify a polypeptide consisting of three amino acids, the answer is five, because, in addition to the three codons necessary for the amino acids, a start codon of AUG (on the mRNA transcript), and one stop codon (UAG, UGA,or UAA on the mRNA transcipt) are also needed. So, in this sense, five codons are needed to specify a polypeptide of 3 amino acids.Improved Answer: The answer is 9. ^ fail XD

How many amino acids are produced by the segment of DNA that has 21 bases?
A segment of DNA with 21 bases would encode for a polypeptide with 7 amino acids. This is because each amino acid is coded for by a sequence of three bases, called a codon. Therefore, 21 bases would be translated into 7 codons, each specifying an amino acid.
The order of nitrogenous bases in DNA determines the order of what in organism?
The order of the Amino Acids in the protein chain.
A chain of amino acids forms what?
A chain of amino acids form a polypeptide chain. Once the polypeptide chain goes under a seris of folds, due to side chain reactions it becomes a functional protien.
Do polypeptide bonds hold nitrogen bases together?
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
What determines how many amino acids is in a polypeptide?
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
Excluding the stop sequence how many nucleotides are necessary to code for a polypeptide that is 100 amino acids long?
300 nucleotides are needed to code for a polypeptide that is 100 amino acids long, because each amino acid is coded for by a sequence of 3 nucleotides (codon), and there are 100 amino acids in the polypeptide.
How are codons used in polypeptide formation?
Four 'types' of nucleotide bases - when they are read three-at-a-time - this is considered to be a triplet-codon. Triplet codons are individually related to one specific amino acid, a polypeptide being a short protein.
How many amino acids can a sequence of 24 DNA bases bases code for?
20
How many amino acids will be in the polypeptide that is formed when uacguacguucaacu is translated?
Five. Each codon consists of a sequence of three nitrogen bases, and each codon codes for a specific amino acid, or a start or stop command.
How many codons are incolved ina polypeoptide that has 5 amino acids?
Simple answer FIVE. Each codon is made up of links. There are three links to the codon. Each codon codes for a single amino acid. A polypeptide is a string of amino acids. The term is usually used for smaller polypeptide chains. Larger chains are usually referred to as proteins although not all proteins are simply polypeptides. Heomoglobin, for example, contains a heme group.
