A genome sequence is the complete list of the nucleotides (A, C, G, and T for DNA genomes) that make up all the chromosomes of an individual or a species. Within a species, the vast majority of nucleotides are identical between individuals, but sequencing multiple individuals is necessary to understand the genetic diversity.
All of the definitions were written by the same Ph.D.-level science writer for consistency and accuracy. Illustrations: Most terms have professionally drawn illustrations to further explain a meaning or concept, or place them in context of the cell or a similar biological setting as a means to better explain the term.
A spontaneous mutation in the genome of an individual organism that is new to that organism's lineage, having first appeared in a germ cell of one of the organism's parents or in the fertilized egg that develops into the organism; i.e. a mutation that was not present in either parent's genome.

The genome of an organism (encoded by the genomic DNA) is the (biological) information of heredity which is passed from one generation of organism to the next. That genome is transcribed to produce various RNAs , which are necessary for the function of the organism.
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
•List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol. Follow the Python code link for information about updates to the list of genes on these pages.
Whereas a genome sequence lists the order of every DNA base in a genome, a genome map identifies the landmarks. A genome map is less detailed than a genome sequence and aids in navigating around the genome. [75] [76] An example of a variation map is the HapMap being developed by the International HapMap Project.
A genome is divided in coding and noncoding regions, and the last step of structural annotation consists in identifying these features within the genome. In fact, the primary task in genome annotation is gene prediction , which is why numerous methods have been developed for this purpose. [ 19 ]
