All mrNAs fold into particular three-dimensional structures that are required for their translation. Incorrect.
Work Step by Step
mRNA does not fold into particular three-dimensional structures. In fact, mRNA strands do not fold at all, they are found freely floating in the cytoplasm of a cell. mRNA strands contain a start codon which is the requirement for their translation, in which a ribosome binds to the start codon and starts translating the codons on the mRNA strand into amino acid chains.
