Explanation:

The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation. In the transcription process, the information from a DNA strand (acts as a template) is copied into a single stranded messenger RNA (mRNA) molecule by matching complementary bases to the original DNA strand using an enzyme known as RNA polymerase. This occurs in the nucleus. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. The endoplasmic reticulum takes the newly synthesized proteins and transports them to the Golgi apparatus. The Golgi apparatus modifies, sorts, concentrates and packs these proteins into sealed droplets called vesicles before sending them to their destination.
