It carries the nucleotide sequence of the DNA to the ribosome in the form of codon sequence for translation, that is, the formation of the polypeptide chain.
The codon sequence of the mRNA codes for the amino acid sequence of the protein.
Transcription<span> proteins assemble at a hairpin loop formed by inverted repeats in the DNA template. RNA polymerase creates a nick in one of the DNA strands and begins to separate the nontemplate from the template.</span>
