Which of the following statements about ribosomes is true?
Ribosomes are only found in prokaryotic cells.
Ribosomes are made up of two subunits, a small subunit and a large subunit.
Ribosomes are responsible for synthesizing DNA.
Ribosomes are membrane-bound organelles.
Ribosomes are found in all living cells, including both prokaryotic and eukaryotic cells. They are made up of two subunits, a small subunit and a large subunit, which work together to read the genetic information in mRNA and link together amino acids to form a polypeptide chain. Ribosomes are not responsible for synthesizing DNA, as this is the job of DNA polymerase. Ribosomes are not membrane-bound organelles, as they are free-floating in the cytoplasm or attached to the endoplasmic reticulum.
Correct option is 2.
