Genomic analysis of Prochlorococcus has revealed
A) the presence of bacteriorhodopsin.
B) variations in ribosomal genes within the same phylotype.
C) complete congruence of genes and genome structure within the same phylotype.
D) variation in functional genes within phylotypes, but high levels of gene conservation between cultured representatives and environmental populations.

Question

Quizplus · Accepted Answer

Genomic analysis of Prochlorococcus has revealed variations in functional genes within phylotypes, but high levels of gene conservation between cultured representatives and environmental populations, indicating a high degree of genome plasticity and adaptation to varying environmental conditions. The presence of bacteriorhodopsin has been observed in some other marine microbes, but not in Prochlorococcus. While there may be minor variations in ribosomal genes within the same phylotype, complete congruence of genes and genome structure within the same phylotype is unlikely.
