To determine:
The result of experiment performed by Fraenkel-Conrat and Singer. Also determine the result of the same experiment if protein was the genetic material of TMV instead of RNA.
Introduction:
Fraenkel-Conrat and Singer collected RNA and protein from different TMV (tobacco mosaic virus) and made a hybrid virus from these molecules. Then they allowed these hybrid viruses to infect the tobacco leaves, which in turn produced new virus particles. The newly obtained viral progeny showed characters identical to the strain from which RNA was extracted, the new progeny showed no resemblance with the strain from which protein was extracted. Hence, they concluded that RNA is the genetic material of TMV.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
