The building block of DNA is called the nucleotide, which is composed of a nitrogenous base (adenine, guanine, cytosine, or thymine), a five-carbon sugar (deoxyribose in DNA), â¦ and one to three phosphate groups.he phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without  de-  one oxygen  -oxy- . There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine.

What is a habitat? The word habitat is Latin for it inhabits. A habitat is a place where a species lives. It is the natural place or environment in which plants, animals and organisms live. Basically, their physical surroundings that influence and is used by any species. Habitats are specific to a population. Each population has its own habitat.
