Nucleotide Databases¶
Core_nt Database¶
What is the Core_nt Database?¶
The Core_nt database is a refined nucleotide sequence database optimized for speed and search relevance. Core_nt excludes some large eukaryotic chromosome assemblies that can be found in the NCBI Genome resource, and is therefore ideal for identifying sequences and finding homologs.
What is in the Core_nt Database?¶
Core_nt contains sequences from the following categories:
Organisms from across the tree of life, including unknown or unclassified organisms.
Single-species environmental samples including DNA or RNA sequences obtained directly from environmental samples, such as soil, water, or air.
Artificially created strands of nucleotides that can be designed to replicate natural genetic material.
How is the Core_nt Database Created?¶
The diagram below depicts how the core_nt database is generated.
