Curiosity must first have been based on human family resemblances, such as similarity in body structure, voice, gait, and gestures.

Such notions were instrumental in the establishment of family and royal dynasties.

All present research in genetics can be traced back to Mendel’s discovery of the laws governing the inheritance of traits. Both aspects of heredity can be explained by genes, the functional units of heritable material that are found within all living cells.

Every member of a species has a set of genes specific to that species. Although scientific evidence for patterns of genetic inheritance did not appear until Mendel’s work, history shows that humankind must have been interested in heredity long before the dawn of civilization.

These are stable identifiers and should be used to cite Uni Prot KB entries.

Each reviewed entry is assigned a unique entry name upon integration into Uni Prot KB/Swiss-Prot. This subsection of the ‘Entry information’ section provides one or more accession number(s).

Most of the mechanisms of heredity, however, remained a mystery until the 19th century, when genetics as a systematic science began.

Genetics arose out of the identification of genes, the fundamental units responsible for heredity.

The first human settlements that practiced farming appear to have selected crop plants with favourable qualities.

Genetics as a scientific discipline stemmed from the work of Gregor Mendel in the middle of the 19th century.

Mendel suspected that traits were inherited as discrete units, and, although he knew nothing of the physical or chemical nature of genes at the time, his units became the basis for the development of the present understanding of heredity.

This indicates the type of evidence that supports the existence of the protein.

Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed. DNA polymerase that promotes microhomology-mediated end-joining (MMEJ), an alternative non-homologous end-joining (NHEJ) machinery triggered in response to double-strand breaks in DNA (Pub Med:20617203).

However Uni Prot KB may contain entries with identical sequences in case of multiple genes (paralogs).
