CONDON
5' end (nucleotides are added from 3' toward 5')
in the ribosome :)
Condon has 3 bases sequences which three consecutive nucleotide specify a single amino acid that is to be added to the polypptide.

Nucleotides in the coding region of DNA are transcribed into mRNA. mRNA, in turn, is translated into a polypeptide via the ribosome. Three (3) nucleotides correspond to one amino acid. In other words, if the nucleotides in question are AAA, those nucleotides will be transcribed into their mRNA complement, UUU, which in turn will be translated into the amino acid phenylalanine via the ribosome. Now, if you remove one of those nucleotides, say the first A of the AAA, everything gets screwed up. You get what is caused a frameshift. Say originally you had AAAUAG. As I mentioned, AAA would eventually become phenylalanine, and UAG is a stop codon, which would tell the ribosome to stop translating: the polypeptide is complete. But if the first A of the AAA is removed -- the ribosome still wants to read in threes! So it will read AAU, and code asparagine instead of phenylalanine, and moreover . .. it will keep translating making a polypeptide much longer than evolution intended!

The sequence of nucleotides is altered and therefore, the amino acid that is to be added to the peptide chain will be altered. hence the protein will be different. This protein can be functionless (will be degraded). If it turns out to be toxic, then there may be symptoms.
