Yas los ntawm qab zib thiab carbon dioxide
Ib pab neeg ntawm University of Bath tau tsim cov yas uas tuaj yeem tsim los ntawm cov khoom siv DNA uas tau yooj yim, thymidine, pom hauv txhua lub hlwb. Nws muaj cov suab thaj yooj yim siv hauv kev sib txuas ntawm cov tshuaj - deoxyribose. Qhov thib ob raw khoom yog carbon dioxide.
