Introns
Proteins determine how a gene is expressed. Proteins are composed of amino acids that are synthesized (put together) by RNA, and RNA is made from DNA. DNA is what you inherit from your parents--very basically, your genes are sections of DNA that code for certain proteins (that are composed of amino acids).

20 Amino Acids
The mRNA sequence CAAGAC codes for the amino acids glutamine (CAA) and aspartic acid (GAC) in that order.
mRNAs code for the 20 standard amino acids found in proteins. Each group of three nucleotides on the mRNA (codon) corresponds to a specific amino acid, as determined by the genetic code.
The sections of DNA called codons code for amino acids.
No, they code for amino acids (in sequence).

It is the code for amino acids
Nucleic Acids to Amino Acids--APEX
No. Amino acids are not always represented by only one codon. Several may code for one amino acid.

There are 64 codons (3-base code) that represent 20 amino acids and 3 stop signals. Click on the related link to see a table of DNA codons and the amino acids for which they code.
From a nucleic acid code to an amino acid code
20 Amino Acids
An mRNA transcript carries the genetic code to the ribosome. tRNA molecules bring amino acids to the ribosome for translation. The amino acids polymerize into functional proteins.
