1. Translation
Objective 4,6

2. 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…

4. Practice Which amino acids match the following codons:
AUG = ______________
UCU = ______________
UCG = ______________
CCA = ______________
GCA = ______________
GGG = ______________
UAA = ______________

6. 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)

7. Review What type of nucleic acid has codons?
What type of nucleic acid has anti-codons?
What type of nucleic acid has genes?

8. RNA
