Tus kab mob genomes Koj, zoo li txhua lwm yam hauv lub cell, siv DNA ua koj li khoom siv. Cov kab mob, ntawm qhov tod tes, tuaj yeem siv RNA lossis DNA, ob qho tib si yog hom nucleic acid. Peb feem ntau xav txog DNA ua ob kab thiab RNA ua ib leeg-tso tseg, vim qhov ntawd yog qhov xwm txheej hauv peb tus kheej lub hlwb
Puas yog ib pawg ntawm cov kab mob uas ua rau muaj kab mob ntawm cov plaub hau ntawm daim tawv nqaij thiab rau tes?
