Answer:
A
Explanation:
Due to mutations in DNA that accumulate at a fairly constant rate , the reduction in melting temperature for hybrid DNA between two mammalian species, it is used to predict how long those species have been since divergence.
Hence option A is correct.
<span>Bio-indicators are macro-invertebrates that detect Water Quality based on how tolerant they are to pollution. The number of species of each type of Bio-indicator (pollution tolerant, intolerant, and semi-tolerant) will calculate the index of the water.</span>

Explanation:
Answer:
The mutated protein would be the target for the new drug therapy.
Explanation:
Cancer occur due to mutation in some important genes that regulate cell cycle as well as cell division.The mutation of tumor suppressor gene such as retinoblastoma,p53,PTEN etc also leads to the onset of cancer.
Now the most important point to note that mutation in the these particular genes result in the formation of abnormal proteins or disease causing proteins.These mutated proteins are the principle cause for the occurrence of cancer.
As a result the mutated protein would be appropriate target for the new drug therapy .The drug will interact with the mutated protein and blocks the toxic activity of the later.
