Translation Objective 4,6
Decoding mRNA • The mRNA strand is divided into smaller parts called codons (words) • A codon is three nucleotides (letters) mRNA= GCG-GAA-UAU • The rRNA (ribosomal RNA) translate the codons into amino acids • Write the Amino Acids for the above three codons here: __________ - ___________ - ___________ using the chart on the next slide…
Practice • Which amino acids match the following codons: • AUG = ______________ • UCU = ______________ • UCG = ______________ • CCA = ______________ • GCA = ______________ • GGG = ______________ • UAA = ______________
Translation • Transfer RNA (tRNA) brings the amino acids to the ribosome • tRNA knows which amino acids to bring because they have anticodons which are complimentary to codons: mRNA= GCG-GAA-UAU codons tRNA= ____-____-____ Answer: CGC-CUU-AUA anticodons • The amino acids brought by the tRNA are connected together to make proteins (genes)
Review • What type of nucleic acid has codons? • What type of nucleic acid has anti-codons? • What type of nucleic acid has genes?
