Answer:
I think it's D but I'm not sure
Answer:
Cro and lambda
Explanation:
In the lysogenic cycle, the viral DNA is within the host DNA, while in the lytic cycle the viral DNA is separated from the bacterial cell, replicating independently from the bacterial DNA. The cro and lambda are DNA-binding repressor proteins of the bacteriophage lambda which bind to different operator sites, i.e., different genetic sequences found between the promoter and the structural gene. These proteins are known to have complementary functions in lytic and lysogenic cycles. The cro protein repressor binds non-co-operatively to operator DNA regions, while the lambda protein contains a domain (carboxy-terminal) that binds co-operatively to operator regions.
True
Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments.
Prior to the experiments being performed, proper planning is done. After the experiment is carried out, the data is noted. Once the data is noted, results are inferred.
If the evidence agrees with the prediction then the hypothesis is being supported and validated. If the result fails to validate the hypothesis then the hypothesis need to be abandoned or modified.
