Protein Synthesis Lab

Today we started off by turning in UP pgs. 15-20 and congratulated Sam for doing well on the first time scribing. Next we jumped right into the lab on Protein Synthesis. This lab was meant to help us further understand the role sof mRNA and tRNA through constructing models of protein synthesis.

LAB: Step One: We had t build a DNA molecule with a specific sequence of nucleotides.

Step Two: Each group had to "unzip" the DNA molecule into two strands.

Step Three: Take the left strand and construct a matching mRNA nucleotide strand (this step is the process of transcripton)

Step Four: Unzip the molecule and take the mRNA strand and take it to the ribosome in the cytoplasm.

Step Five: Match up the bases of the mRNA with the ones from tRNA. (Translation)

Step Six: Attach the amino acids and the polypeptide bonds to the correct molecules.

Step Seven: Detach the amino acid chain from the tRNA's

HOMEWORK:

Finish Lab in Up (15-20), UP 27-28, and Tribune Arrticle(11/23)

THE NEXT SCRIBE IS....
