If DNA can’t leave the nucleus, how do you think the DNA instructions get to the ribosomes in the cytoplasm?
koban [17]

Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.

<h3>Transcription</h3>

Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.

After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.
