In eukaryotic cells, the process of protein synthesis occurs in a specific sequence that ensures the proper formation of proteins. The first step is transcription, where the DNA sequence of a gene is copied into messenger RNA (mRNA). This occurs in the nucleus, where the DNA resides. During transcription, RNA polymerase synthesizes the mRNA strand based on the complementary DNA template.

After transcription, the mRNA undergoes processing before it can be translated into a protein. This processing includes the addition of a 5' cap and a poly-A tail, as well as the splicing of introns (non-coding regions) out of the mRNA. The final processed mRNA exits the nucleus and enters the cytoplasm, where it will be translated.

The final step is translation, during which the ribosome reads the processed mRNA sequence and synthesizes the corresponding protein by assembling amino acids in the correct order. This occurs in the cytoplasm, where ribosomes are located, either floating freely or bound to the endoplasmic reticulum.

Thus, the correct order of events in protein synthesis for eukaryotes is transcription, processing, and then translation. This sequence is crucial for ensuring that the genetic code is accurately converted into functional
