Enzyme RNA polymerase joins nucleotides together
RNA polymerase.
^^ I'll edit rather than replace this because I'm uncertain, but I'd actually go with DNA Polymerase III.
RNA does not links amino acids , linkage is done by enzyme peptidyl transferase .

RNA polymerase is the enzyme that adds and links complementary RNA nucleotides during transcription
The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
A DNA nucleotide is composed of the 5-carbon sugar deoxyribose, a phosphate group, and one of four nitrogen bases; adenine (A), thymine (T), cytosine (C), and quanine (G). A molecule of DNA is composed of two strands of nucleotides. The nucleotide strands are oriented such that the sugar and phosphate groups alternate down the outside of the strand, and the nitrogen bases are oriented toward the center of the two strands. In a DNA molecule, the two strands of nucleotides pair according to the base-pairing rule, which states that adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G). The nitrogen bases of the complimentary strands of DNA are held together by hydrogen bonds. Because of the 3-D structure of the nucleotides, the two DNA strands twist into a double helix, often likened to a twisted ladder. Refer to related links for illustrations.
Both are made from smaller subunits that are joined by covalent bonds. In the case of proteins, these subunits are called amino acids. They are joined by special covalent bonds called peptide bonds. In the case of nucleic acids, the subunits are called nucleotides, which are a combination of a sugar (ribose or deoxyribose), phosphate group, and one of four possible bases (adenine, thymine, guanine, or cytosine). The nucleotides are covalently bonded along the "ladder" of the DNA molecule. Another feature of polymers is that the covalent bond that links the subunits (or monomers) is formed by dehydration synthesis, that is, a removal of a water molecule.

Amino acids
Condensation(removal of a water molecule) links amino acids together to form chains called polypeptides. Protein synthesis possibly? Technically what forms the actual bond between the amino acids is dehydration, where an enzyme binds to the amino acids, and removes any H2O, and thus a bond is formed.

The physical structure is called a double-helix.
It is dehydration synthesis. Basically it is a process in which a molecule of water is removed from the reactant to join reactants together.

The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule - that's how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
there is no "paper" molecule... rather a combination of starches and protein links e.t.c.
