Protein synthesis in an animal cell occurs:
Correct answer: D. On ribosomes present in the cytoplasm as well as mitochondria
- A. Only on the ribosomes present in cytoplasm
- B. Only on the ribosomes attached to the nuclear envelope and endoplasmic reticulum
- C. On the ribosomes present in the nucleolus as well as the cytoplasm
- D. On ribosomes present in the cytoplasm as well as mitochondria
Explanation
Protein synthesis is the process by which an mRNA is read by ribosomes to synthesise a polymer of amino acids known as a protein. The process is known as translation. The process of protein synthesis occurs in different organelles, such as mitochondria, chloroplasts, cytoplasm, and rough endoplasmic reticulum in animal cells. Protein synthesis is performed by structures known as ribosomes. Ribosomes are present in mitochondria, cytoplasm, endoplasmic reticulum (ER), etc.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
