If by "four chemicals" you mean nucleotides, then they are as follows:
1. deoxyadenosine monophosphate or adenine
2. deoxyguanosine monophosphate or guanine
3. deoxycytosine monophosphate or cytidine
4. deoxythymine monophosphate or thymidine
The chemical bonds holding DNA molecules together are
1. phosphodiester bond in the polynucleotide strand
2. hydrogen bond between the complementary nitrogenous bases on adjacent polynucleotide strands.
The atoms in a molecule of methane are held together by covalent bonds. In methane, a carbon atom is bonded to four hydrogen atoms through sharing of electrons, forming a stable structure. These covalent bonds provide the necessary attraction to hold the atoms together in a molecule.
Four heme groups, so I think four molecules of oxygen can be transported by one molecule of haemoglobin.
The bonds are ionic or covalent.
Within the molecule it is the covalent bonds which hold the atoms together. The facts that the molecule is polar or that the substance is in the solid state are irrelevant. If you were trying to ask what holds the molecules together to make the solid, then it is dipole-dipole forces and van der Waals forces.
A molecule typically consists of three main parts: atoms, which are the basic building blocks; bonds, which are the connections that hold the atoms together; and functional groups, which are specific groups of atoms that confer distinct properties and reactivity to the molecule. These components work together to define the structure and function of the molecule in various chemical processes.

Covalent bonds hold a dextrose molecule together.
True
Covalent bonds
generally covalent bonding
intermolecular forces examples are dispersion forces
Covalent bonds
Bonds hold atoms together. There are hydrogen bonds, ionic bonds, and covalent bonds.
The bonds are ionic or covalent.
The bonds that hold the two chains of an insulin molecule together are disulfide bonds. These bonds form between cysteine amino acid residues in the A and B chains of the insulin molecule, creating a stable structure essential for its biological function.
hydrogen bonds. The other bonds are covalent bonds.
