Please see below a diagram of the retroviral RNA genome structure and the corresponding DNA provirus. I have labelled several loci with arrows and numbers. Please complete the numbered and lettered lists in the box below with the corresponding RNA and DNA cis-regulatory elements for red arrows (1-6) and genomic regions with blue arrows (A-D). Note that cis-regulatory elements contain those required for RT and for expression of the provirus after integration. (8 points)   Based on the depiction above, briefly in a paragraph with or without illustration describe the main steps of the Reverse Transcription process whereby the genomic RNA is copied into double stranded DNA. Please refer to the main cis-regulatory elements and their function during Reverse Transcription. (8 points)        

52-year-old female, asymptomatic. The patient underwent an abdominal ultrasound (US) for evaluation of elevated cholesterol during a routine physical exam. She has no right upper quadrant pain, fever, nausea, or history of liver disease. Physical Exam: Unremarkable; no palpable liver edge or mass.Labs: Liver function tests (LFTs), complete blood count (CBC), and tumor markers (CA 19-9) are all within normal limits. A single, 3 cm anechoic (echo-free) lesion is identified in the right lobe of the liver. The lesion has a thin, well-defined back wall with imperceptible walls and posterior acoustic enhancement. Which of the following is more likely a complex cyst and does not belong to this patient?
