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 stop codons are there in genetic code?
In the genetic code, there are three stop codons: UAA, UAG, and UGA. These codons signal the termination of protein synthesis during translation, indicating that the ribosome should stop adding amino acids to the growing polypeptide chain. Each of these stop codons does not code for any amino acid, effectively marking the end of the protein-coding sequence.
How is a genetic code is redundant?
There are 64 codons, that code for only 20 amino acids. This make the genetic code redundant - because different codons can code for the same amino acid.This provides some protection against mistakes - because a replacement of a single base may end up coding for the same amino acid - causing no change to the final protein product.
What is the porpuse of transcription?
DNA is coded with 4 symbols: A (adenosine), C (cytosine), G (guanine) and T (thymine), just like computers are coded in binary (0,1). In this genetic code, rests the necessary information to synthetize proteins. But he problem here is that DNA is built with blocks called nucleotides and proteins are built with blocks called aminoacids. So, in traslations rests the step to move from DNA to proteins. Codons are nature's translation of nucleotide to aminoacid. Any combination of 3 given nucleotides, say AGC (an adenine, guanine, cytosine codon) is translated to Seryne, an aminoacid. Every posible combination of 3 nucleotides form a codon, and every codon has an exact translation. There are only 20 posible aminoacids, hence, some combinations code for the same aminoacid.
What are the three codonds that would tell the ribosome to stop producing the amino acid chain?
The three codons that signal the ribosome to stop producing the amino acid chain are UAA, UAG, and UGA. These are known as stop codons, and they do not correspond to any amino acids. When the ribosome encounters one of these codons during translation, it triggers the release of the newly synthesized polypeptide chain, effectively terminating protein synthesis.

All amino acids are specified by only one codon?
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.
What 3 codons do not carry amino acids?
There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).
Can an amino acid be specified by more than one codon?
Yes, each amino acid has several codons that correspond to it. Please see the related link for a chart which shows this. For example, UUU and UUC both code for Phenylalanine. However, if you are asking if a codon can code for more than one amino acid, the answer is no (but there are exceptions). This means that UUU codes for Phenylalanine - not for any other amino acids. Codons are made in sets of three bases to match the anticodons in corresponding sets of three bases.
What meaning do the first and last codons have for protein synthesis?
Codons are used for making amino acids. Some codons will tell the ribosomes to start tell the tRNA to make the amino acids or to stop making amino acids. I like to think of the start/initiator/promoter codon(AUG) as a capital letter in a sentence and the stop/terminator codons(UAA, UAG, and UGA) as periods in a sentence.
What condons do not code for amino acids?
Stop codons (also known as nonsense codons) do not code for amino acids. These include UAG, UAA, and UGA. When a stop codon is encountered during translation, it signals the termination of protein synthesis.
There are how many different kinds of RNA codons?
A codon consists of a series 3 nucleotides. There are 4 possible nucleotides. These 4 nucleotides could appear in any combination with any number of repeats. That being the case, to find the possible number of mRNA codons requires simple math:4 * 4 * 4 = 64So there are 64 possible codons.

Why this function is important?
You have not specified any function.
Why are roughing and finishing cuts made?
Roughing cuts are used to bring the diameter of the workpiece down to the rough size of what is specified on the engineering drawing or instruction. This gives some lee-way for any mistake we may make at some stage.We then use a finishing cut to bring the workpiece down to a specified length/diameter, and also a specified surface finish in some cases.
Which amino acids help with bodybuilding?
actually you will be adviced by any knowledgeable person in the gym you train, to take the whole chain of aminoacids during and after training or as a regular supplement in your diet. As me you will find this to really work. An easy explanation is that they help the protein chain. I advise you to visit the wikipedia aminoacids article for further studies wich I provide the link below.
What were wagons used for?
Wagons are vehicles used for transporting goods or any specified reasons they are still used in some contries in 2011
