AT RICH SEQUENCES Meaning and
Definition
-
AT-rich sequences refer to regions of DNA or RNA that have a high proportion of adenine (A) and thymine (T) bases compared to the other nucleotides, guanine (G) and cytosine (C). These sequences are characterized by a relatively low GC content and are often found in the genomes of various organisms.
AT-rich sequences have several important biological roles. One such role is their involvement in DNA replication and transcription. These sequences are known to have a propensity for adopting secondary structures, such as DNA hairpin loops or stem-loop structures in RNA. These structures can play a regulatory role by influencing processes like initiation or termination of transcription.
Another significant characteristic of AT-rich sequences is their association with functional genomic elements. In eukaryotes, these sequences are often found in promoter regions, where they play a role in regulating gene expression by influencing the binding of transcription factors. They are also found in enhancer elements and can facilitate the binding of regulatory proteins.
AT-rich sequences are also frequently associated with centromeres and telomeres, the structural and functional regions of chromosomes. In these regions, their high AT content contributes to the stability and function of these critical chromosomal structures.
Overall, AT-rich sequences have diverse biological functions and are involved in various processes in DNA replication, transcription, gene regulation, and chromosome structure.
