Biology
Transcription: DNA can be transcribed to RNA
Translation: RNA can be translated into Protein
Replication: DNA can be replicated into DNA
Genetic Code Exceptions
RNA can be reverse transcribed to DNA.
RNA can be copied to RNA (in some viruses)
Triplet Code: Ribosomes translate mRNA three nucleotides at a time
Codons: Nucleotide Triplets
tRNA’s have an anticodon complimentary to the codon.
Depending on the codon, different amino acids will be added or translation will be terminated.
There is redundancy in the genetic code.
64 codons but only 20 amino acids.
Start Codon: AUG (codes for methionine)
Stop Codon: UAA, UGA, UAG (do not code for amino acids)
61 codons code for amino acids
Wobble Pairing
Multiple codons code for the same amino acids
Third base pair in the codon is flexible
Non-Watson-Cricke Base Pairing
