MECHANISMS OF SUPPRESSION AND AMPLIFICATION OF RIBOSOMAL RNA GENES IN DROSOPHILA MELANOGASTER
Compensation is a mechanism by which Drosophila melanogaster can increase its ribosomal RNA repeat unit multiplicity by up to two-fold. The phenomenon occurs under defined genetic conditions, is restricted to the X chromosome ...
PHYSICAL AND GENETIC CHARACTERIZATIONS OF CLONED FRAGMENTS OF BACILLUS SUBTILIS BACTERIOPHAGE SP01 DNA (HYDROXYMETHYL URACIL, THYMINE, HOST-KILLING)
Bacillus subtilis bacteriophage SP01 causes pleiotrophic cessations of host metabolism and kills the host. Nonetheless, a large number of restriction fragments, representing approximately two thirds of the genome, can be ...
