AATT

AATT is a term that can refer to several different things, depending on context. It functions as an acronym for various organizations, programs, or initiatives, and it also denotes a short DNA sequence. Because the same four letters are used across domains, AATT is not a single, fixed concept; readers should use surrounding text to infer which sense is intended.

In molecular biology and genetics, AATT typically refers to the four-nucleotide sequence consisting of adenine-adenine-thymine-thymine. This tetranucleotide can appear in DNA sequences and is often discussed in relation to overall base composition, AT-rich regions, or methylation patterns. It is not by itself a functional unit, but it can occur in regulatory elements or structural DNA contexts.

In other fields, AATT is an acronym for organizations, programs, or initiatives; exact meanings will vary by country and discipline. Commonly, such acronyms represent professional associations, educational programs, or research projects. Because many entities may use AATT, disambiguation is typically required in literature and databases.
