The active gene bank of the International Crops Research Institute for the Semi-Arid Tropics in Patancheru, India. A gene bank is a type of biorepository that serves to preserve the genetic information of organisms. Gene banks are often used for storing the genetic material of species that are endangered or close to extinction.
The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations. It is produced and maintained by the National Center for Biotechnology Information (NCBI; a part of the National Institutes of Health in the United States) as part of the International Nucleotide Sequence Database Collaboration (INSDC).
DNA banking is used to conserve genetic material, especially that of organisms that face extinction. This is a more prominent issue today due to deforestation and climate change, which serve as a threat to biodiversity. The genetic information can be stored within lambda phage and plasma vectors. The National Institute of Agrobiological ...
As genetic information moves largely online there is a transition in germplasm information from a physical location (seed banks, cryopreserving) to online platforms containing genetic sequences. In addition there are issues in the collection germplasm information and where they are shared.
DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA, otherwise known as DNA sequencing. The practical aspects revolve around designing and optimizing sequencing projects (known as "strategic genomics"), predicting project performance ...
The polyelectrolyte theory of the gene reasons that DNA can maintain its shape regardless of mutations because the negative charges on the phosphate backbone dominate the physical interactions of the molecule to such a degree that changes in the nucleic acid sequence, the encoded information, do not affect the overall physical behavior of the ...

The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a historical hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (), goes through stages resembling or representing successive adult stages in the evolution of the ...
