DNA Replicates by a Semiconservative Mechanism

DNA Replicates by a Semiconservative Mechanism

DNA Replicates by a Semiconservative Mechanism. Grow cells in 15 N and transfer to 14 N. Analyze DNA by equilibrium density gradient centrifugation. Presence of H-L DNA is indicative of semiconservative DNA replication. from Lodish et al ., Molecular Cell Biology, 6 th ed. Fig 4-29.

DNA Replication

DNA Replication

DNA Replication. 1.  Process by which DNA makes a copy of itself 2. Occurs during S phase of interphase before cell division 3. Extremely rapid and accurate (only 1 in a billion are incorrectly paired) 4. Requires many enzymes & ATP (energy)

Chapter 8 From DNA to Proteins

Chapter 8 From DNA to Proteins. DNA rap. Look at the image of the mice below. Notice anything that seems odd?. These mice have had a jellyfish gene ( Green Fluorescent protein ) inserted into their DNA by way of a virus. The virus inserted the GFP gene into the DNA of the mice.
