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.
