An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides known as ribonucleic acid, and is single-stranded.Click to see full answer. Thereof, why is mRNA single stranded?Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. Messenger RNA (mRNA) carries the genetic information that directs the synthesis of proteins. Some viruses use RNA instead of DNA as their genetic material. Most of the RNA, however, does not code for proteins.Similarly, is RNA double or single stranded? Unlike double-stranded DNA, RNA is a single-stranded molecule in many of its biological roles and consists of much shorter chains of nucleotides. However, a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA. Then, which type of RNA is single stranded? Ribonucleic acid (RNA) is typically single stranded and contains ribose as its pentose sugar and the pyrimidine uracil instead of thymine. An RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure.What is an example of mRNA?Every DNA sequence that eventually ends up as a protein is an example of mRNA. Every DNA sequence that eventually ends up as a protein is an example of mRNA. The messenger RNA or mRNA is simply a transient carrier of information on what to synthesise from the nucleus to the ribosomes.
