Deoxyribonucletoide stands for DNA, the genetic material of the organisms. This DNA is the hereditary material of the organism coding molecule is passed on to the generations, so it has to be replicated, form a transcript and translated to proteins.
The DNA transcription process produces a transcript chemical molecule with exactly the same language as of DNA called RNA. This RNA carries the information for the synthesis of protein molecule so it acts as a messenger molecule and is known as mRNA.
