Dna starts in the nucleus and then the message contained in the dna is sent to what organelle to make a protein?

Ribosome

Explanation:

In eukaryotes DNA synthesis and transcription occurs inside the membrane bound nucleus. The message contained in the DNA is transcribed to mRNA a process called Transcription which occur inside the nucleus. The product of transcription is a mRNA transcript which is transported to the cytoplasm where it is translated into proteins a process called translation.

Protein translation occurs in the Ribosome and endoplasmic reticulum which are found in the cytoplasm of the cell.

the answer would be 3

the correct answer is:

a population changes in response to a change in the environment.
