Final answer:
Eukaryotic ribosomes are an example of ribonucleoprotein and are transcribed from special non-gene regions of DNA. They are present in large quantities in most cells.
Step-by-step explanation:
Eukaryotic ribosomes are an example of ribonucleoprotein. They are composed of both structural and catalytic ribosomal RNAs (rRNAs) and distinct polypeptides. The nucleolus in eukaryotes is specialized for the synthesis and assembly of ribosomes. Therefore, options 1) and 2) are correct.
However, option 3) is incorrect. Ribosomes are present in relatively large quantities in most cells, including eukaryotic cells. For example, in E. coli, there are between 10,000 and 70,000 ribosomes present in each cell at any given time.
So the correct answer is option 1) Example of ribonucleoprotein, and option 2) Transcribed from special non gene regions of DNA.
Eukaryotic ribosomes are an example of ribonucleoprotein, are not transcribed from special non-gene regions, and are not limited in quantity by cell volume.
Eukaryotic ribosomes are indeed an example of ribonucleoprotein, as they are complex macromolecules composed of ribosomal RNA (rRNA) and ribosomal proteins. They are not transcribed from special non-gene regions of DNA; instead, the rRNA components are synthesized in a specialized organelle in eukaryotic cells called the nucleolus, which is known for synthesis and assembly of rRNAs. Furthermore, eukaryotic cells typically contain a large number of ribosomes to meet the protein synthesis demand, contradicting the statement that they are present in small quantities due to cell volume limitations. Thus, of the options given, only (1) is correct: ribosomes are an example of ribonucleoprotein.
