If 35% of the bases in a region of the mouse genome are cytosine, what percentage in that region are adenine? 
 A. 15%

B. 20%

C. 30%

D. 35%

E. 40%

A. 15%

Explanation:

DNA is composed of four nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Chargaff's rule of base pairing states that A always pairs with T, while G always pairs with C. The total distributed percentage of the four 4 nitrogen bases must be equal to 100%. In this case, the C content is 35%, thereby G=35% (i.e., equal to C content), while the remaining 30% must be equally divided between T=15% and A=15%.

true is the final answer!

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
