BIOL 1001 Chapter : BIOL Chapter 1

1. What interactions serve to stabilize/hold DNA together in its secondary structure? Explain how this stabilizes DNA in its aqueous environment.

Would really appreciate if anyone explain me carefully since I'm 1st year in BIOL

Mutations in histidine 84 of EF-Tu result in slower GTPhydrolysis.
-Daviter et al., J Mol Biol 332(3):689-699 (2003).
The mutation alters the activation energy of GTP hydrolysis. Theactivation energy is 8.4 kcal/mol higher in the mutant than in thewild type. How does activation energy affect: (1) equilibrium, (2)reaction rate?

1. Discuss the role of DNA in general terms of heredity, as an information molecule for storage and the ability to transmit genetic information.

2. Discuss the diversity in genome sizes among organisms and if genome size is a good predictor of biological (organismal) complexity.

I would really appreciated if anyone explain these carefully since I'm 1st year in BIOL
