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.
In the Windows operating systems, a locale is a set of user preference information related to the user's language, environment and/or cultural conventions.
In computer science, a local variable is a variable that is given local scope. Local variable references in the function or block in which it is declared override the same variable name in the larger scope. In programming languages with only two levels of visibility, local variables are contrasted with global variables.
