Preview - Exploring Dna Replication - Eths

Part 2 - Challenge 6: Changing the Supply

1.  Return the speed to NORMAL and SETUP the simulation, then press GO/STOP.

2.  Unwind the DNA, separate the strands and attach polymerase. Increase the number of free nucleosides to approximately 150 bases.

3.  Observe the replication the TOP STRAND of DNA ONLY.

4.  Now, decrease the number of free nucleosides to approximately 15 bases. 

5.  Attach polymerase to the bottom strand. Observe the replication the bottom strand of DNA now.  Press GO/STOP to end the simulation.

Questions

Please answer the questions below.

Question 10:  How does increasing the number of nucleotides affect your DNA replication?  Is it easier or harder?  Why? Use your observations to justify the reason.

Question 11:  How does decreasing the number of nucleotides affect your DNA replication?  Is it easier or harder?  Why? Use your observations to justify the reason.
