Verified step by step guidance

Understand the concept of cDNA: Complementary DNA (cDNA) is a form of DNA synthesized from a messenger RNA (mRNA) template in a process called reverse transcription.

Identify the enzyme involved: The enzyme responsible for synthesizing cDNA from an mRNA template is reverse transcriptase.

Differentiate between the options: Recognize that rRNA, tRNA, and DNA are not templates for cDNA synthesis in this context. The correct template is mRNA.

Clarify the role of reverse transcriptase: This enzyme catalyzes the formation of cDNA from an mRNA template, which is crucial in processes like cloning and gene expression studies.

Review the incorrect options: RNA polymerase synthesizes RNA from a DNA template, DNA polymerase synthesizes DNA from a DNA template, and helicase unwinds DNA strands. These do not apply to cDNA synthesis from mRNA.
