Question: Why do both hepadnaviruses and retroviruses require reverse transcriptase when
Why do both hepadnaviruses and retroviruses require reverse transcriptase when their genomes are double-stranded DNA and single-stranded RNA, respectively?
Relevant QuestionsWhat are the similarities and differences between viruses and viroids? What are overlapping genes? Give examples of viruses that have overlapping genes. Replication of both strands of DNA in adenoviruses occurs in a continuous (leading) fashion. How can this happen without violating the rule that DNA synthesis always occurs in a 5′ S 3′ direction? Explain why an Escherichia coli strain that is His− is an auxotroph and one that is Lac− is not. Why is it difficult in a single experiment to transfer a large number of genes to a recipient cell using transformation or transduction?
