What are the other components of the DNA molecule besides nitrogenous bases?

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.

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/
