Well, these similarities are contained in the "factors" (genes) that are in the "key" that accesses the living nature, ie, the cells of all living organisms. Surely you've seen or heard, somewhere, that all living beings have as its lower part, a structure called a cell. To better understand, let's make a comparison. Imagine a house! To build it up Mason organizes the bricks, which together form the walls. These walls form the various rooms, which grouped ultimately form the house. With multicellular living organisms something similar happens: the cells are grouped to form different tissues, these in turn form organs and systems, which finally together form the body. The cells have "smaller parts". Are the cellular organelles and compounds that together perform various functions on your metabolism, thus enabling the continuity of life. But those terms, masterfully, this fascinating and complex world phone? As you may have noticed in the central part of the cell is its nucleus. In it are contained various information inherent to life in a filamentous network called chromatin. The chromatin is formed by the molecule of deoxyribonucleic acid (DNA), which during cell division wraps and condenses, becoming identifiable. The structures formed are the chromosomes which aims to carry the genes. The word chromosome was proposed by biologist Wilhelm WaldeyerHartz in 1888, which is Greek meaning "body color". That's because when you observe a stained cell under a microscope, perceives a tangle of colored wires located inside the nucleus.

Pa, ove sličnosti su sadržana u "čimbenika" (geni) koji su u "ključu" koji pristupa dnevni prirodu, tj. stanicama svih živih organizama. Sigurno ste vidjeli ili čuli, negdje, da sva živa bića imaju kao svoj donji dio, struktura zove ćeliju. Da bi bolje razumjeli, idemo napraviti usporedbu. Zamislite kuću! Da ga podigne Mason organizira cigle, koji zajedno tvore zidove. Ti zidovi osnivanjem raznih soba, koje grupirane u konačnici tvore kuću. S višestaničnih organizama živih nešto slično se događa: stanice su grupirani u obliku različitih tkiva, to je pak oblik organa i sustava, što je na kraju zajedno čine tijelo. Stanice imaju "manjih dijelova". Jesu li stanični organela i spojevi koje zajedno obavljaju različite funkcije na metabolizam, na taj način omogućiti kontinuitet života. Ali ti uvjeti, majstorski, to fascinantno i složen svjetski telefon? Kao što ste možda primijetili u središnjem dijelu ćeliji je njegova jezgra. U njemu su sadržani razne informacije svojstvenu života u vlaknaste mreže pod nazivom kromatina. Kromatina je formirana molekulu deoksiribonukleinske kiseline (DNA), koja tijekom stanične diobe oblozi i kondenzira, postaje prepoznatljiv. Strukture formirane su kromosomi koji ima za cilj da nose gene. Riječ kromosoma je predložio biolog Wilhelm WaldeyerHartz u 1888, što je grčka znači "boja karoserije". To je zato što kad promatramo umrljana stanicu pod mikroskopom, percipira splet boja žice nalaze unutar jezgre.
