The five-letter word "ACTTA" is commonly used in biology and genetics to represent a DNA sequence. Each letter represents a nucleotide base: A for adenine, C for cytosine, T for thymine. The doublet "TT" indicates that the DNA strand has a pair of thymine bases. The spelling of the word follows the International Phonetic Alphabet (IPA) transcription, where "A" is pronounced as /eɪ/, "C" as /siː/, and "T" as /tiː/. The doublet "TT" sounds like /t/ followed by a short, voiceless /ɪ/ sound.
