Dna sequences

Definition

DNA sequences refer to the precise order of nucleotides in a strand of DNA, which is essential for the coding of genes and the function of living organisms. These sequences determine genetic information and play a crucial role in various biological processes, including replication, transcription, and translation. Understanding DNA sequences has significant implications in fields like genetics, medicine, and even fractal geometry, where patterns and structures are analyzed.
