The intermediate molecule that is synthesized to carry the information coded in the DNA is RNA.
According to the central dogma the DNA gets converted to RNA by the process of transcription. Transcription synthesizes the RNA copy of the DNA segment with the help of an enzyme RNA polymerase. RNA then gets converted to protein by the process of translation.
The enzyme DNA polymerase is responsible to convert a single double-stranded DNA molecule to two double-stranded DNA molecules as its products. The DNA is converted to RNA through the transcription process. The enzyme RNA polymerase develops RNA molecule which is complementary to a gene-encoding DNA segment. Translation makes proteins from mRNA molecules. The ribosome is responsible to generate the polypeptide chain of amino acids using mRNA as a template. The polypeptide chain then folds up and becomes a protein.
