Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Protein synthesis takes place on the
A
plasma membrane
B
nucleus
C
ribosomes
D
microbodies
Explanation: 

Detailed explanation-1: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-2: -The most prominent substructure within the nucleus is the nucleolus (see Figure 8.1), which is the site of rRNA transcription and processing, and of ribosome assembly. As discussed in the preceding chapter, cells require large numbers of ribosomes to meet their needs for protein synthesis.
