Marco Caserta,Silvia Schwarze,Stefan Voßly in the development of molecular biology. The ubiquitous occurrence of this potential pathogen, its haploid nature (chromosome mol. wt. 2.5 × 10. daltons) allowing the expression of recessive characteristics, its ability to grow in a variety of media, and its rapid growth rate are major factors co

About 1500 mutations leading to a requirement for histidine have been described in the cluster of genes specifying

Many different bacteriophages have been described; for some of these, such as the T-even phage of ., extensive information is available, while for others, relatively little is known. An attempt has been made to discuss only those bacteriophages for which the genetic analysis is particularly c
