Ribosomes are the site of:
- ARNA synthesis
- BLipid synthesis
- CProtein synthesis
- DDNA replication
Show answer and explanation
Correct answer: (c) Protein synthesis
Explanation
Ribosomes are the site of protein synthesis. They read the genetic message in messenger RNA and join amino acids, brought by transfer RNA, in the right order to make a protein (translation). They are made of ribosomal RNA and proteins and are found in both prokaryotes and eukaryotes.
- RNA is made by transcription, mainly in the nucleus.
- Lipids are made in the smooth endoplasmic reticulum.
- DNA replication happens in the nucleus, during the S phase of the cell cycle.
