What is the start codon and what amino acid does it code for?
AUG. The amino acid methionine. Bases read; adenine-uracil-guanine
When a protein is synthesized what amino acid is always the first amino acid that is positioned during any protein synthesis?
"AUG" actually corresponds to a region of code on mRNA and is NOT an amino acid. The tRNA that has the anticodon 5' CAU 3' and recognizes AUG is a tRNA charged with Methionine. Therefore, methionine is the first amino acid incorporated into a growing polypeptide. Note this is true for only eukaryotes, prokaryotes have N-formyl methionine as their first amino acid.
What amino acid is represented by only one codon?
There are two amino acids that only correspond to one codon:Tryptophan whose codon is UGGMethionine whose codon is AUG
Where does the amino acid table use the code from?
I'm unsure what your question means, but if I interpreted correctly, the codes on the amino acid table are codons. So they are the codes that would be found on the mRNA. If you are looking up an amino acid on the table, just use the one it says under the codon you want to translate. For example, if the codon is AUG, the amino acid is just methionine. No need to do anything more.
What amino acid is technically not an amino acid?
proline is not an amino acid it is an imino acid
The start codon is?
mRNA sequences ATG and AUG. They start coding for an amino acid and begin the protein synthesis.
Which codon tells where a sequence of amino acids is to begin?
i think its ACT/UGA. ya, tht sounds right now tht ive typed it out
What is a possible mRNA sequence of the amino acid valine?
GUU, GUC, GUA, GUG
What amino acid has AUG?
METHIONINE
What is the start codon and what amino acid does it code for?
AUG. The amino acid methionine. Bases read; adenine-uracil-guanine
What is the first amino acid on the protein?
AUG, or methionine.
The amino acid that initiates protein synthesis?
AUG

Is tryptophan the starting codon for mRNA?
No, tryptophan is an amino acid, not a codon. The start codon is AUG, which codes for the amino acid methionine.
The first amino acid inserted into a new polypeptide chain in eukaryotic cells is always?
The first codon is usually the start codon AUG. AUG is normally the only codon for the amino acid methionine. There are exceptions. The E.coli lactose operon contains four genes: lacI, lacZ, lacY and lacA. The amino acid sequence for all four of these genes begins with methionine. Only lacZ and lacY begin with AUG. LacI begins with GUG, which normally codes for valine. LacA begins with UUG, which normally codes for leucine. Still, the starting amino acid seems always to be methionine. Perhaps the ribosome is primed with methionine transfer RNA when it begins its translation of the messenger RNA. However, the site of translation initiation is not always at an AUG start codon. For the DNA and amino acid sequences of the E.coli lactose operon see http://www.ncbi.nlm.nih.gov/nuccore/146575?report=graph.
What amino acid is encoded by the initiation codon AUG?
The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.
First codon to form an amino acid?
AUG. Methionine is the first and start codon in forming polypeptides.
