Question

Which of the following cell structures contains the highest concentration of RNA? (A) centriole (B) lysosome (C) chromosome (D) nucleolus ​

Answer 1

Chloroplasts. Hint: Maximum amount of RNA is found in the non- membrane bound structure located within the controlling centre of a cell. This control centre contains the genetic material of an organism and is surrounded by two layers of membrane.

Answer 2

The Cell structure that contains the highest concentration of RNA is NUCLEOLUS. (OPTION D)

RNA -

• RNA is a nucleic acid that is single-stranded and constructs proteins inside our body.
• A Nucleolus is a membrane-less structure present in the nucleus.
• It forms the Nucleolar Organizing region of the chromosomes.
• Its main function is to synthesis RNA in the nucleus so-referred to as the storehouse of RNA.
• The nucleolus contains a high amount of RNA and ribosomal proteins.
• It contains genes for the transcription of ribosomal protein required for the translation process.
