Ushbu maqolada genomlar xilma-xilligi va ularning strukturaviy tashkil etilishi zamonaviy molekulyar biologiya yutuqlari asosida tahlil qilinadi. Tadqiqotda turli organizmlar — prokaryotlar, eukaryotlar hamda viruslar genomlarining hajmi, shakli va gen tarkibi jihatidan farqlanishi ilmiy asosda yoritilgan. Shuningdek, genomning asosiy strukturaviy darajalari, ya’ni DNKning ikki spiral tuzilishi, genlarning ekzon-intron tashkiloti, xromatin va xromosoma darajasidagi murakkabligi izchil bayon etiladi. Maqolada kodlovchi va kodlamaydigan DNK qismlarining o‘zaro nisbatlari hamda ularning funksional ahamiyati alohida e’tiborga olingan.
