Detailed explanation-1: -Small organelles found in our cells. They are responsible for assembling amino acids into proteins during protein synthesis.
Detailed explanation-2: -To build proteins, the two ribosomal subunits, small and large, assemble together to form the complete ribosome. It has binding sites for mRNA and transfer RNA (tRNA) molecules. The large subunit sits on top of the small subunit, with the mRNA template sandwiched in between the two.
Detailed explanation-3: -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.
Detailed explanation-4: -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.
