Answer: The correct answer is rRNA and protein.
Explanation:
Ribosome is a cell organelle present in the cytoplasm of all living cells. It is a site of protein synthesis in all type of cells. It is made up of two sub-units namely, small sub-unit and large sub-unit.
Both the sub-units are formed by rRNA (ribosomal RNA) and associated proteins. rRNA is ribozyme, that is, it is a ribonucleic acid with catalytic ability. The protein component helps in providing the structure to the ribosome.
Ionic bonds are referred to two elements/molecules that form when one is classified as metal and another is classified as non-metal. Covalent bonds are two non-metal elements that bind together. They differ in several ways. Ionic bonds have a better force of attraction due to the metal element, whereas covalent bonds are formed using the Van de Waals force (which makes it weaker). Ionic bond also has higher melting and boiling point because of its force of attraction as compared to the covalent bond. Similarly, ionic bonds react to electricity where covalent does not.
