RT Journal Article SR Electronic T1 Mutant of Bacterium paracoli 5099 with an Altered DNA: Identification as a Flavobacterium JF Science JO Science FD American Association for the Advancement of Science SP 893 OP 894 DO 10.1126/science.160.3830.893 VO 160 IS 3830 A1 Rosenkranz, Herbert S. A1 Ellner, Paul D. YR 1968 UL http://science.sciencemag.org/content/160/3830/893.abstract AB A difference in the base composition of the DNA of Bacterium paracoli 5099 and of a "mutant" (No. 1975) derived from it was found. This is in accordance with the finding of others. However, biochemical tests revealed that the "mutant" was a Flavobacterium, whereas the parent strain belonged to a species of Escherichia. The base composition of the DNA of the "mutant" is similar to that reported for the DNA of Flavobacterium.
