Molecular Biology of the Gene

Please indicate all of the appropriately paired scientists and experiments.

• Griffith -- discovered bacteria's 'transforming factor' using harmless and pathogenic versions of Strep

• Rosalind Franklin -- used x-ray crystallography to photograph the shape of DNA

• Hershey & Chase -- determined that DNA (not protein) is the genetic material using bacteriophages

• Watson & Crick -- determined the 3D structure of DNA

• Chargaff -- determined the 1 purine : 1 pyrimidine ratio

Prokaryotes are to eukaryotes like...

• no nuclei are to organelles present in the cell.

• smaller is to larger cell size.

• transcription in the cytoplasm is to transcription in the nucleus.

• more complex is to less complex replication, transcription, and translation process.

• no introns is to introns in the RNA.

Which of the following is/are true concerning translation?

• It requires the interaction of mRNA, rRNA, and tRNA.

• It takes place in the nucleus.

• It requires exons, but not introns.

• It uses 3 consecutive nucleotides to code for a specific amino acid.
