It is a #"DNA"# molecule synthesized from template #mRNA# in reverse transcription

Explanation:

#"cDNA or complementary DNA"# has nucleotide sequence complementary to the processed #"mRNA# from which it has been synthesized in a process called reverse transcription that is catalyzed by enzyme i.e reverse transcriptase.

#cDNA# being synthesized from single stranded #"mRNA"# is firstly synthesized as a single stranded molecule. And it remains single stranded until #"PCR(polymerase chain reaction)"# is carried out. In PCR that is aided by #"DNA polymerase"# (e.g Taq DNA polymerase) , it gets it's double stranded form.
