USF The chromosomes of the species known as Vulcans together contain 24% adenine. Apply Chargaff’s rules to calculate the percentages of thymine, guanine, and cytosine bases in their genomes, respectively. Group of answer choices 26%, 24%, 26% 76%, 24%, 76% 24%, 26%, 26% 26%, 26%, 24% 24%, 52%, 52% Not enough information has been provided to calculate the other percentages. 24%, 24%, 24%

Thymine = 26%,

Adenine = 26%

Guanine = 24%

Cytosine = 24%

Explanation:  

Chargaff's stated that the DNA of any cell has the same content of purine (A and G) and pyrimidine (T and C) bases. In the DNA molecule, T pairs with A (T–A), and G pairs with C (G–C). In consequence, according to this base pair-rule, the amount of Thymine (T) should be equal to the Adenine (A), and the amount of Cytocine (C) should be equal to the Guanine (G).

In this example, the content of A is 26%, and thereby the amount of the remaining bases is: 48 % (26 + 26 = 52 >> 100 - 52 = 48), where C= 24% and G=24%.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
