cDNA of the gene/mRNA for which you want to make complementary RNA is cloned into special plasmid vectors that have promoters at either ends of the multiple cloning sites (MCS). Using RNA polymerase and nucleotides you can now synthesize RNA complementary to the original mRNA. This is called complementary RNA (cRNA).

Adenine bonds to what?

Adenine bonds with Thymine.Adenine complementary stand is Thymine in DNA but in RNA Thymine is replaced with Uracil. This means that Adenines complementary stand is Uracil in RNA.


What is the unique complementary base pairing in RNA?

In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between cytosine (C) and guanine (G).


In RNA thymine is absent and what is substituted?

Uracil is substituted. Uracil is complementary to adenine in RNA. In DNA, adenine is complementary to thymine.
