Unit 3 Lesson 4: DNA Questions
1. What analogy represents the process of DNA replication?
The analogy that accurately represents the process of DNA replication is folding a piece of paper and cutting out a shape which could then be replicated with another piece of paper. The scissors break the bonds down the center.
2. How do complementary base pairing rules make DNA replication possible?
Complementary base pairing rules help DNA replicate because without base pairings the DNA would not be held together and therefore would not be able to be replicated and seperated.
3. What are enzymes? What enzymes play major roles in DNA replication? What are those roles?
An enzyme is a protein that speeds up biochemical reactions.
4. What are leading and lagging strands? What does 5'->3' and 3'->5' mean?
Leading strands (5->3) are the strands that are being synthesized in the same direction as the growing replication. They flow on a direct path. Lagging strands (3->5) are the strands that do flow in the same direction as the leading strands but do not flow in a direct path.
5. What is "junk" DNA and is the descriptive term "junk" appropriate? Why or why not?
Junk DNA is a DNA in cells that doesn't do anything for them. This Junk DNA is no use for the cells which is why scientists named it, "junk DNA" meaning junk as it's just a waste and there is no purpose for it.
Even though DNA replication follows standard base pairing rules there is still diversity on earth. This is true because when different organisms live in different environments they must adapt and when they adapt they change and become different from the other organisms around the world.
