Blood cultures collected for the recovery of N. gonorrhoeae or N. meningitidis require:
a. no special methods.
b. more than 0.025% sodium polyanethol sulfonate (SPS).
c. transfer from Vacutainer tubes to culture broth within 1 hour of collection.
d. less than 0.025% SPS.
D
Both organisms are sensitive to SPS; therefore, the content of SPS in blood culture broths should not exceed 0.025%. In addition, if blood is first collected in Vacutainer tubes (Becton Dickinson and Company, Sparks, MD), which may contain concentrations of SPS toxic to gonococci and meningococci, then the blood specimen must be transferred to the broth culture system within 1 hour of collection.

Eukaryotic and prokaryotic organisms differ in how they process genetic information. Which statements best explain one of these differences?
A. In prokaryotes, genes are transcribed directly into polypeptides. In eukaryotes, genes are transcribed into RNA which is used to assemble polypeptides. B. In prokaryotes, translation occurs before genes are transcribed into mRNA. In eukaryotes, genes are transcribed into mRNA which is then translated into polypeptides. C. In prokaryotes, translation of the mRNA begins before transcription is complete. In eukaryotes, transcription and modification of the mRNA is completed before translation begins. D. In prokaryotes, introns are removed before genes are transcribed into mRNA. In eukaryotes, introns are removed after genes are transcribed into mRNA.

A) phenotype. B) gene pool. C) population. D) genotype. E) allele.
