👉 In biology, a chromoisomer is a type of biomolecule that consists of two identical strands of DNA or RNA linked together. Chromoisomers are important for genetic information exchange and regulation because they can bind to specific regulatory proteins, which can affect gene expression. The structure of a chromoisomer typically involves two complementary strands of DNA or RNA that are separated by the nucleotide sequence in question. The two strands can be joined together by the formation of a double helix structure, which allows for
