What is RNA? Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: âDNA makes RNA makes proteinâ.
Report Abuse. Messenger RNA (mRNA) is RNA that encodes and carries information from DNA during transcription) to sites of protein synthesis to undergo translation in order to yield a gene product. mRNA life cycle. The brief life of an mRNAs begins with transcription and ultimately ends in degradation.1] Anti-sense mRNA During transcription, double stranded DNA produces mRNA from the sense strand; the other, complementary, strand of DNA is termed anti-sense. Anti-sense mRNA is an RNA complementary in sequence to one or more mRNAs.
