There are 21 amino acids found in eukaryotes.
Three bases represent a codon, and each codon codes for one amino acid.
A codon is three bases long - so this section of mRNA would have 4 codons; UGA-UUC-AGU-AAC.Each codon relates to a specific amino acid (but several codons can code for the same amino acid, for example both UUU and UUC code for the amino acid Phenylalanine).Normally if you have four codons, such as this section of mRNA, the maximum number of amino acids you could have would be four. However, the first codon in this section, UGA, is actually a STOP codon. This means that when the ribosome reaches this codon, no further amino acids will be joined.This means that no amino acids could be coded for with this section of mRNA. (If the order of the codons was reversed, making the STOP codon last, then the answer would be three).
AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
The mRNA is coded by the tRNA to make a protein.

Each codon codes for only one amino acid, or a codon is a start or stop codon, but no codon codes for more than one amino acid.
The anticodon would be UAG, and the amino acid coded for is isoleucine.

There is only one corresponding amino acid for each codon. Each codon codes specifically for one amino acid (however, an amino acid can be coded for by several different codons). For example: CAU codes for Histamine (and not any other amino acid) But, CAC also codes for Histamine.
If all the nucleotides are protein coding with no control sequences, then 33. Each amino acid is coded for by 3 nucleotide bases. 99 divided by 3 = 33.
The actual process is pretty complicated. If you're just looking for a simple overview, the answer is that any given sequence of three bases codes for a specific amino acid. Since there are four (basically...) bases, that means there are 4x4x4 = 64 possible combinations. That's more than the number of biologically important amino acids by quite a bit, so it's actually normal for more than one sequence to code for the same amino acid. Also, certain particular combinations are used for signalling (start here, stop here) rather than for amino acid selection.
Transcription of the DNA into messenger RNA (mRNA). mRNA contains the anti-codons for ribosomal binding, so the transfer RNA (tRNA) can add the corresponding amino acid. This part is known as translation.
AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
That MAY have happened 3.5 billion years ago ... but not today. DNA carries the codes for amino acid sequences. RNA transfers the codes. Ribosomes link the amino acids into proteins. Amino acids don't code for proteins, genes do. The base sequence in the genes codes for how the amino acids should be sequenced to make proteins.

In the genetic code, a sequence of three nucleotides forms a codon, which codes for one amino acid. So for each amino acid, there are three nucleotides. Therefore, 600 nucleotides are needed to make 200 amino acids.
