A very interesting and compact little book.
However, although I understand its goal to be brief, it occasionally throws out some terms, concepts, or abbreviations without explaining what they are (e.g. it didn't bother to explain that "kb" stands for "kilobases"). Also, there are occasionally little things that seem a bit off or not very clear. For example, the book says that Calgene created the Favr Savr tomato by "knocking out the expression of the gene coding for the enzyme endo-polygalacturonase [PG]..." (89). This makes it sound like they knocked out the gene or shut off its expression, when, in fact, they left it intact but inserted an antisense PG gene that would produce mRNA complementary to the PG mRNA, thereby interfering with the PG protein production.
But, overall, this is quite an informative and educational book that touches upon many intriguing topics. And I think it would be a good read for anyone interested in exploring the wide range of molecular biology topics/applications (and has at least a little bit of knowledge in biology).
