Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.

<span>The population dynamics of the Warbler species differ from what's documented by Scott Sillett and colleagues one migration issues.
The Warbler species are non migratory species, while Scott Sillet and colleagues have been studying migratory species. The Warbler species were even taken to other islands, in some cases, in order to give them the </span>security of additional breeding populations, this because their population dynamics is not a migratory one. The studied species by Scott Sillet and colleagues, on the other hand, have migratory population dynamics: they pass their Summer time in <span>New Hampshire and and their Winter time in Jamaica.</span>
Answer:
telomere hypothesis
Explanation:
Telomere hypothesis -
Telomere -
It is the area where there are repetitive nucleotide sequence at the very end of the chromosome that does not allow the ends from fusing with the other chromosomes and even from deteriorating .
<u>according to the hypothesis , the cells have shorter DNA sequence which divide throughout the life .</u>
<u>hence , the correct term for the given statement is - telomere hypothesis . </u>
Answer: peptide bonds
Explanation: I think that's the answer.
