But you cannot tell if this an example of DNA replication or RNA transcription. Describe three ways that you can tell the two processes apart.arrow_forwardthe human immunodeficiency virus HIV uses RNA rather than DNA to encode genetic information. During infection, however, HIV uses an enzyme known as reverse transcriptase to generate double-stranded DNA. Generally speaking, how would the enzyme generate a double strand of DNA from a single strand of RNA?arrow_forward
