A gene is a segment of DNA that is the basic unit of heredity.

A gene in molecular biology and in genetics indicates the fundamental hereditary unit of living organisms.

The genes correspond to portions of the genome located in precise positions within the DNA sequence and contain the information necessary to ultimately encode molecules that have a function, such as RNA or proteins. During the reproductive phase of the cell the genes are present in the chromosomes, which in human cells are present in 23 pairs of homologous chromosomes, with the sole exception of the gametes, which present a single copy of each chromosome.

A gene is an information unit in a locus of deoxyribonucleic acid (DNA) that encodes a functional product, proteins for example. It is the molecular unit of genetic inheritance, because it stores genetic information and allows transmitting to offspring. The genes are found in the chromosomes, and each occupies a correct position called a locus. The set of genes of a species is called a genome.

unless they converted, many non-christians (mainly jews and muslims) were persecuted

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place.
