The genotype of an organism is its complete set of genetic material. [1] Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. [2] The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also ...
The Code was thought to be the earliest Mesopotamian law collection when it was rediscovered in 1902—for example, C. H. W. Johns' 1903 book was titled The Oldest Code of Laws in the World. [32] The English writer H. G. Wells included Hammurabi in the first volume of The Outline of History , and to Wells too the Code was "the earliest known ...

Genetic code. A series of codons in part of a messenger RNA (mRNA) molecule. Each codon consists of three nucleotides, usually corresponding to a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C. This is mRNA, which uses U ( uracil ). DNA uses T ( thymine) instead.

The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [12] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
