DNA replication is said to be is semi-conservative, meaning that one parent strand is always passed on to the daughter helix of DNA. Why is this an important and safe way to replicate?
How many guanines are in a DNA molecule 1000 base pairs long if 20% of the molecules consist of adenines? Show your math and include a verbal explanation of your reasoning.
What are the other components of the DNA molecule besides nitrogenous bases?What are the other components of the DNA molecule besides nitrogenous bases?

It just works that way. You can imagine other ways in which DNA could be replicated that would work just as well. *shrug* It provides for a certain amount of error detection/correction; a mismatch can be nicked, then a new strand synthesized.

Number of bases = 2000
Adenine = 20%
T = 20%
G+C = 100% - 20% - 20% = 60%
G = 30% = 0.30 * 2000 = 600 bases

check out this research group they have a message board you can use......http://boinc.bakerlab.org/rosetta/
