T- Collaborative group- UNDER THE COLLABORATION SPACE (Post notes)
MAKE A PPT and share with the class.
Replication:
What are the players and what do they do? (Helicase, SSB, primase, DNA polymerase I and III, ligase,
okazaki fragments, direction of replication)
Include: origin of replication? Replication fork? Semi conservative replication.
How is the structure of DNA related to the function of replication?
-
Efficiency of replication
Leading and lagging strands and antiparallel-arity
Mutations:
What happens if DNA makes a mistake in copying the strand?
What are the causes of mutations?
What are point mutations are there and how does that affect the message (or not)?
Differences in prokaryotes and eukaryotes
What is the difference between DNA of prokaryotes and eukaryotes?
In your answer be sure to include: How many chromosomes? Shape? Origins of replication?
Chromosomes and Karyotypes
How many chromosomes do we have?
What is a karyotype and what does it show? How is it used?
How can you tell the difference between males and females?
How can you determine genetic abnormalities using a karyotype and show examples.
Problems with replication? Telomeres
What are telomeres? Where are they located?
Do prokaryotes have them? Explain.
What is the association between telomeres and aging? Explain.
