What else can I help you with?
What are two functional parts of a charged RNA?
codon on mRNA and the amino-acid specified by the codon
How many amino acids does each condon code for?
No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp). An example of an amino acid that is specified by more than one amino acid is Alanine, which is specified by any of the following combinations: GUU, GUC, GUA, GUG. Because most amino acids have more than one codon, the genetic code is called "degenerate".
Are some aminoacids not specified by any codons?
No, all 20 standard amino acids used in protein synthesis are specified by at least one codon. Each codon on the mRNA corresponds to a specific amino acid during translation, as determined by the genetic code.
What is the term for a 3-nucleotide sequence on mRNA that codes for an amino acid?
the three nucleotides on a mRNA that codes for a amino acid is called a codon
There can be more than one for the same amino acid?
Yes, multiple codons can code for the same amino acid in the genetic code. This redundancy in the genetic code is known as degeneracy. For example, the amino acid leucine is specified by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.
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 are two functional parts of a charged RNA?
codon on mRNA and the amino-acid specified by the codon
The genetic code is degenerate?
Each amino acid can be specified by more than one codon.
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.
How many amino acids does each condon code for?
No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp).

Because most amino acids have more than one codon, the genetic code is called "degenerate".
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.
Which amino acid is coded by the DNA codon TAC?
It is a triplet of bases (codon) coding for the amino acid tyrosine
How many amino acids does a codon contain?
A codon contains three amino acids. Each codon in mRNA corresponds to a specific amino acid in a protein sequence.
What amino acid is AUG or GUG?
The codon AUG represents the amino acid methionine, which serves as the start codon for protein synthesis. The codon GUG typically codes for the amino acid valine.
Complementary to an mRNA codon?
it depends on the codon spcified. The tRNA will have the complementary strand along with an amino acid, for which is specified by the mRNA. if the mRNA codon was "CGA" the tRNA codon would have an amino acid and the complementary codon of "GCU"
What amino acid is coded for by the codon AUC?
The anticodon would be UAG, and the amino acid coded for is isoleucine.
For which specific amino acid does each codon code in the genetic code?
Each codon in the genetic code codes for a specific amino acid. For example, the codon "AUG" codes for the amino acid methionine.
