A 28-year-old musician comes to your clinic, complaining of a "spot" on his penis. *He states his partner noticed it 2 days ago and it hasn't gone away. He says it doesn't hurt. He has had no burning with urination and no pain during intercourse. He has had several partners in the last year and uses condoms occasionally. His past medical history consists of nongonococcal urethritis from Chlamydia and prostatitis. His vital signs are unremarkable. On visualization of his penis there is a 6-mm red, oval ulcer with an indurated base just proximal to the corona. On palpation the ulcer is nontender. In the inguinal region there is nontender lymphadenopathy. What disorder of the penis is most likely the diagnosis?A) Condylomata acuminataB) Genital herpesC) Syphilitic chancreD) Penile carcinoma

- Arsenic is a toxic element found in both aquatic and terrestrial environments. Scientists have found genes that allow bacteria to remove arsenic from their cytoplasm. Arsenic enters cells as arsenate that must be converted to arsenite to leave cells. Figure 1 provides a summary of the arsenic resistance genes found in the operons of three different bacteria. E. coli R773R773 is found in environments with low arsenic levels. Herminiimonas arsenicoxydans and Ochrobactrum tritici are both found in arsenic‑rich environments.Figure 1. Operons found in three selected bacteria for arsenic removalResearchers claim that bacteria that live in environments heavily contaminated with arsenic are more efficient at processing arsenic into arsenite and removing this toxin from their cells. Justify this claim based on the evidence shown in Figure 1.AThere are multiple operons controlling the production of proteins that process and remove arsenite from cells in both H. arsenicoxydans and O. tritici. In contrast, E. coli has only one operon devoted to arsenic removal.BBoth H. arsenicoxydans and O. tritici contain the arsR gene that codes for a repressor that turns on the operon to eliminate arsenite from the cell.CBoth O. tritici and E. coli contain the arsD gene, which codes for a protein that helps remove arsenite from the cell.DBoth H. arsenicoxydans and O. tritici. have more arsenic resistance genes than has E. coli.
