| what is the code? | universal, each triplet codes for the same amino acids in all organisms. |
| what is the code? | universal, each triplet codes for the same amino acids in all organisms. |
| features of the genetic code1 | 2 amino acids are coded by only a single triplet (UUG) |
| features of the genetic code 2 | the remaining amino acids are coded for by between 2 and 6 codons each |
| in eukaryotes | in the length of DNA corresponding to a gene, there are coding portions known as extrons, and there are non coding proteins named introns. the genetic code is used only for exons (coding region of a gene) |
| it is the triplets of mRNA bases... | that are translated into the correct sequence of amino acids, the genetic code is often given as mRNA codons |
| features of the genetic code 3 | the codon is always read in the 5' --> 3' direction |
| what is a denerate code | which is a genetic code, (refers to the fact that multiple codons, or sets of three nucleotides, can code for the same amino acid during protein synthesis) |
| what is an mRNA codon | sequence of three adjacent nucleotides in mRNA that codes for an amino acid. STOP codons dont code for amino acids |
| mRNA codon = | UGU ; DNA triplet |
| transcribed strand = | ACA : DNA |
| triplet, non-transcribed strand = | TGT |
| what is the start of the sequence always in the codon | AUG,this codes for the amino acid MET (methionine), which is later removed |
| what are the 3 codons which do not code for amino acids (STOP CODONS) | UAA, UAG, UGA, marks the end of a polypeptide chain |
| what is the code? | universal, each triplet codes for the same amino acids in all organisms. |
