This book arose from a project called the La Jolla Summer Workshop on Molecular 

 Techniques in Developmental Biology. This is an annual enterprise, but it is not clear 

 whether the book represents one workshop or a selection from a series of successive ones. 

 That the latter is the case is suggested by the fact that in four of the 1 1 contributions the 

 most recent literature cited dates from 1971 or earlier. No reasons are given for 

 publishing this particular collection of papers, nor is it clear whether more books of this 

 kind are to be expected. 



The contributions, each by a recognized specialist, describe a variety of techniques and 

 procedures down to the minutest detail. They therefore constitute the best possible 

 substitute for personal training, and as such are of great value. There is no common theme 

 in the book, and the best we can do is to briefly characterize the contributions one by 

 one as follows: organelles and membranes from rat liver; rat tissue proteins; steroid 

 receptor proteins; protein separation by gel filtration; enzyme synthesis in germinating 

 seeds; RNA polymerases from Dictyostelium; DNA from eukaryotic cells; quantitative 

 measurement of RNA synthesis; nucleic acid hybridization on filters; tRNA species; and 

 hybridization and reassociation of nucleic acids from cells of higher animals. The last 

 contribution is by far the longest (80 pp.); the others range in length from about 10 to 

 over 30 pages.
