In cell biology, precursor cells —also called blast cells —are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells. In embryology, precursor cells are a group of cells ...
BLAST (biotechnology) In bioinformatics, BLAST ( basic local alignment search tool) [ 3] is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.
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).
Gene bank. 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 is designed around the preservation of genetic information. Gene banks are often used for storing the genetic material of species that are endangered or close to extinction.
Sequence alignment. In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [ 1] Aligned sequences of nucleotide or amino acid residues are typically represented ...
A seed bank (also seed banks, seeds bank or seed vault) stores seeds to preserve genetic diversity; hence it is a type of gene bank. [ 1] There are many reasons to store seeds. One is to preserve the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops.
Users. 30 million (as of 2024) G2A.COM Limited (commonly referred to as G2A) is a digital marketplace headquartered in the Netherlands, [ 1][ 2] with offices in Poland and Hong Kong. [ 3][ 4] The site operates in the resale of gaming offers and others digital items by the use of redemption keys. G2A.COM’s main offerings are game key codes for ...
The Protein Data Bank ( PDB) [ 1] is a database for the three-dimensional structural data of large biological molecules such as proteins and nucleic acids, which is overseen by the Worldwide Protein Data Bank (wwPDB). These structural data are obtained and deposited by biologists and biochemists worldwide through the use of experimental ...
