Understand the role of reverse transcriptase: it is an enzyme that synthesizes DNA from an RNA template, a process called reverse transcription.
Recall that during normal DNA replication, DNA polymerase uses a DNA template to synthesize new DNA strands, but reverse transcriptase works differently.
Recognize that reverse transcriptase reads the sequence of an RNA molecule and synthesizes a complementary DNA strand based on that RNA sequence.
Eliminate other options: proteins and lipid membranes are not templates for nucleic acid synthesis, and DNA template is used by DNA polymerase, not reverse transcriptase.
Conclude that the template used by reverse transcriptase is RNA, making 'an RNA template' the correct answer.
