DNA reverse and complementary sequence generator

DNA or RNA reverse complementary sequence generator converts provided sequence into:
  • Reverse DNA or RNA sequence
  • Complementary DNA or RNA sequence
  • Reverse Complement DNA or RNA sequence
Input sequence:
Complementary sequence:
Reverse sequence:
Reverse complementary sequence:
Complementarity: In molecular biology, complementarity is a property shared between two nucleic acid sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position will be complementary. Two bases are complementary if they form Watson-Crick base pairs. The degree of complementarity between two nucleic acid strands may vary, from total complementarity to none. This tools calculates total complementary sequence.
Complementary DNA: Complementary DNA is often used in gene cloning or as gene probes or in the creation of a cDNA library. When scientists transfer a gene from one cell into another cell in order to express the new genetic material as a protein in the recipient cell, the cDNA will be added to the recipient (rather than the entire gene), because the DNA for an entire gene may include DNA that does not code for the protein or that interrupts the coding sequence of the protein (e.g., introns). Partial sequences of cDNAs are often obtained as expressed sequence tags.
