Protein synthesis (translation) occurs at which of the following locations within eukaryotic cells?
A
Nucleus
B
Mitochondria
C
Ribosomes
D
Golgi apparatus
Verified step by step guidance1
Understand that protein synthesis, also known as translation, is the process by which ribosomes in a cell create proteins, following transcription of DNA to RNA in the cell's nucleus.
Recall that ribosomes are the cellular structures where translation occurs. They can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum, forming the rough ER.
Consider the role of the nucleus, which is primarily involved in transcription, where DNA is transcribed into mRNA, not translation.
Recognize that mitochondria have their own ribosomes and can synthesize some proteins, but the majority of protein synthesis in eukaryotic cells occurs in the cytoplasmic ribosomes.
Note that the Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion, but it is not the site of protein synthesis.
