Suggestion for light-weight molecular biology book for comp sci student

Hi folks,

I work as a software developer and we have a co-op student who is leaving us in one month (after his 8 month stay). I'd like to present him with a gift before he leaves to finish the rest of his computer science credits.

It happens that I did all my college degrees (B.sc, M.sc, etc) in biochemistry/molecular biology and he often expressed interest in these subjects. So the gift of choice I have in mind is some moderately-priced book that goes into some details on the more "fun" aspects of biology and present these materials in an engaging way.

Ideally, this book should have some light-weight introductions to the following subjects with a bit of computational tie-backs:

Population genetics
- Pedegrees, Mendelian genetics
- Some of Kimera' stuff

Molecular genetics:
- Nucleic acids
- DNA damage, mutation, cancer
- DNA -> RNA -> Protein
- Epigenetics
- Antiobiotics, antiobiotic resistance

Bioinformatics:
- SNP's
- MSA's

Biotech:
- Protein engineering (i.e. chimeras)

It will be great if you guys have some suggestions on a good book that fit some of these descriptors.

Thanks!
