The four main nucleotides are Guanine (G), Cytosine (C), Thymine (T) and Adenine (A). DNA is a universal code which means that each nucleotide will have the same meaning in almost all species. There are a few exceptions however, including Viruses with RNA genomes instead of DNA genomes. In these cases, Thymine is switched with a nucleotide called Uracil (U) and so the four nucleotides become G, C, U & A.
Yes, there are 4 main nucleobases (or nucleotides):
Guanine
Adenine
Thymene and
Cytosine
They join in sequence in what is know as specific base pairing - apart from mutations.

Yes. Carbohydrates, proteins, nucleic acids, and lipids.
The DNA of all living organisms is composed of the same four nucleotides. Very rarely however, other nucleotides may be found in DNA in addition to the common four.
The DNA of all living organisms is composed of the same 4 nucleotides. These 4 nucleotides make up all DNA.
Of course! Did you not pay attention in class again! I am ashamed of you.

No. Only living organisms have cells. Although stalagmites and stalactites appear to grow, it is not due to the reproduction of cells or living organisms. Stalagmites and stalactites are composed of atoms which are connected into molecules. They are made of the same things as any other rock.

Although DNA is composed of the same four nucleotides in all organisms, the sequence of nucleotides is different for each species
Organisms are composed of the same chemical elements that are found in non living matter. The matter is the same, only the organization of that matter is different. In scientific terms, organisms contain information that other matter does not. Otherwise, there is no difference.
