Which of the following best describes ribosomes?

Hollow cytoskeletal elements that act as organizers for the cytoskeleton, especially in cell division

Contain digestive enzymes to breakdown non-functional organelles and foreign bodies that enter the cell

The site of protein synthesis.

Dense spherical body in the nucleus which are the synthesis site for ribosomal RNA and ribosomal subunits

Houses all genetic material for the cell including DNA and RNA.

Expert Solution

Out of the given options:

Option 1 is not correct because they are nucleoptroeinaceous structures composed of rRNA and proteins, and are not cytoskeletol elements.

Option 2 is not correct as this refers to lysosomes

Option 3 is the correct answer because all the protein synthesis in a cell occurs with the help of ribosomes. hence they are known as protein factories of the cell or sites of protein synthesis.

Option 4: This option is not correct as ribosomes are not present in nucleus and the given description refers to Nucleolus.

Option 5: The description refers to nucleus.
