Each nucleotide consists of a sugar in the middle of a phosphate group and a nitrogenous base .
There are two classes of bases. Two are purines (double-ringed structures) and two are pyrimidines (single-ringed structures).Very basically, they are made of a nitrogen base, a pentose (5 carbons) sugar and a phosphate group.
nucleic acids
The nucleus of what? There are all sorts of nuclei including atomic nuclei and cell nuclei. Atomic nuclei are made of protons and neutrons. Cell nuclei are made of lipids, protein, DNA and many other chemicals.
the thalamic nuclei is made of unmyelinated axons which are gray matter
Amino acids are made up of the elements nitrogen, hydrogen, carbon, oxygen, and sulfur. Proteins are made up of amino acids.
Macromolecules made of amino acids are called proteins.

Yes, all eukaryotic cells - including plant cells - have a nucleus.
tissues are made of specialized cells that do have nuclei

Ice & dust.
No. Proteins are made of amino acids.

Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
Proteins, which are made of peptides, which are made up of amino acids
Amino acids are made up of the elements nitrogen, hydrogen, carbon, oxygen, and sulfur. Proteins are made up of amino acids.
