Its Thursday!

Today in class we did a lab that was kind of like a fallow up on our last lab when we built the DNA. We built the DNA again then unzipped then made the other side RNA. That was to show transcription. Then we unzipped the mRNA from the DNA strand and moved it to the ribosome in the cytoplasm where translation occurs. Then we had to construct the three tRNA molecules and place three basses on it that are complementary to the first three nucleotides of the mRNA strand. The three nucleotides on the tRNA are called anti~codons. After that step we attached the amino acid to the tRNA molecule by its R~group. Then we disconnected the a.a chain from the tRNAs and the tRNAs from the mRNA and can be reused. This activity was called "Protein Synthesis Activity".
