DNA is coded to RNA, which must travel from the nucleus to the cytoplasm to be read. Why does the cell need to transcribe the DNA into RNA rather than copying the DNA directly? (1 point) DNA requires too much energy to code; building RNA is more efficient.

DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.

DNA cannot be copied; it must be translated to RNA and then back to DNA.

DNA cannot be read by ribosomes; they can only read RNA.
