Concept #1: Meselson-Stahl Experiment

Practice: The Meselson-Stahl experiment demonstrated that DNA replication produces new molecules of DNA each containing…

Practice: The DNA of a phage was injected into the bacterial host, but the protein coat remained outside. The viral DNA directed the host to replicate the new phage viruses. Which scientist(s) are associated with this finding?

Additional Problems
DNA replication is:  a. Conservative b. A one-step process c. Semi-conservative d. Not carried out in prokaryotic cells
The process by which DNA reproduces itself is:  a. Protein synthesis b. Aerobic respiration c. Semi-Conservative Replication d. Substrate-phosphorylation e. Photosynthesis
When DNA replicates:  a. The original DNA is not affected and a new double-stranded DNA is made from two new strands of DNA b. One strand of the original DNA ends up in each of the new DNA molecules c. The original DNA unwinds, and multiple copies of a region are transcribed before the DNA closes back up d. Transcription factors determine where to begin DNA replication e. A cell that was diploid (2N) will now be tetraploid (4N)
Each newly replicated molecule of DNA contains one conserved strand from the original DNA molecule. a. Trueb. False
