BIOMOLECULES AND ENZYMES

Detailed explanation-1: -ATP not only stores energy, it is one of the building blocks of RNA-along with UTP, CTP, and GTP. Molecular machines inside all cells, called RNA polymerases, link these building blocks together into long chains to make messenger, transfer, ribosomal, and other types of RNA.

Detailed explanation-2: -Apart from its roles in energy metabolism and signaling, ATP is also incorporated into DNA and RNA by polymerases during both DNA replication and transcription. When ATP is used in DNA synthesis, the ribose sugar is first converted to deoxyribose by ribonucleotide reductase.

Detailed explanation-3: -Answer and Explanation: This statement is false, because RNA is not made from amino acids but is made from nucleotides containing nitrogenous bases just like DNA. It is proteins that are made up of amino acids. Both DNA and RNA are genetic material that are made up of nucleotides.

Detailed explanation-4: -ATP is a component of RNA and a substrate for the first step of protein synthesis.
