Chromosome Aberrations caused by Radioactive Thymidine

CHROMOSOME aberrations in onion root tips treated with 2-14C-thymine deoxyriboside (thymidine) and with 2-14C-thymine have been studied. It has been found that radioactive thymidine gives a significantly higher frequency of aberration than equivalent amounts of radioactive thymine. Since thymidine is a precursor of deoxyribonucleic acid thymine1,2 and… (More)
