Codons Bases that code for amino acid are called a codon (triplets eg. AUG) there are only 20 amino acids and about 64 possible codons first two nucleotides are consistent for a particular amino acid, but the third nucleotide can vary and still code for the same amino acid this third amino acid is called the wobble position this allows for more than one codon to code for an amino acid in the case of error

Codons

Types of RNA Messenger RNA (mRNA) - is a copy of a portion of the original DNA strand carries the RNA copy of the DNA code for one or more genes in a series of codons; one codon codes for one amino acid Ribosomal RNA (rRNA) - made of 2 subunits work together to make ribosome that is capable of reading mRNA from 5’ to 3’ and assembling amino acids to make protein Transfer RNA (tRNA) - capable of attaching to an amino acid at top near the acceptor stem; at bottom has anticodon loop that is the compliment of the codon found on mRNA
