An experiment conducted to study protein synthesis,radioactive thymine, and radioactive uracil were aIDed to a cultreof human cells. A few hours later, the culture was analyzed andradioactive mRNA was found
a) Explain how an mRNA molecule is produced
b) Explain why the mRNA produced is radioactive
part 2) In a different experiment, radioactive uracil wasaIDed to a culture of human cells undergoing DNA replication. Whatwill be the characteristic of the resulting DNA in terms ofradioactivity? Explain
