For clarity, this module's discussion of transcription and translation in eukaryotes will use the term "mRNAs" to describe only the mature, processed molecules that are ready to be translated. .
The key difference between transcription and translation is that transcription refers to the process of producing a mRNA molecule for the DNA of a gene while translation refers to the process of synthesizing an amino acid sequence from the transcribed mRNA molecule. . "Translation" literally means "to carry across"; that's what translation means.

. With the genes bound in the nucleus, transcription occurs in the nucleus of the cell and the mRNA transcript must be transported to the cytoplasm. The translation occurs in the cytoplasm of the cell, specifically, at the ribosome, the process of protein formation happens. This is possible because prokaryotic cells lack a nuclear membrane, so transcription and translation occur in the same region. Plants also invest significant energy and biomass to construct and maintain the translation apparatus. Also, in eukaryotes, RNA molecules need to go through special processing steps before translation. .
