Options
(a) uracil
(b) adenine
(c) thymine
(d) deoxyribose sugar
Correct Answer:
thymine
Explanation:
Autoradiography is the study of labelled precursors like ³H by knowing the movement of radioactivity with the help of photographic films and emulsions at short intervals. ¹⁴C and ³H are incorporated in bases like thymidine, urindine and amino acids to study the structure of DNA and proteins. Radio tracer technique shows that DNA is in double helical form.
