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?
RNA
