Centromere is the part of sister chromatids which will be radio active. Centromere is responsible in joining the two sister chromosomes.A pair of non radioactive homologous chromosome replicate in presence of radioactive DNA precursors, hence both sister chromatids of each replicated homologous chromosome will incoorparate radioactive precursors
Identifying the parts of the resulting sister chromatids that will be radiactive is possible with use of radioactive dye and Xray photography. By using radioactive dye and bonding agents, we can identify particular stretches of DNA that corresponds to certain amino acids sequences.
No all rock dont have to go through a complete life cycle......i mean some could it but it dont have to be in any exact order ..... so your answer would be false
