Which pair of nitrogen bases are correctly matched?
|
|
adenine with cytosine
|
|
|
adenine with thymine
|
|
|
cytosine with thymine
|
|
|
guanine with adenine
|
Explanation:
Detailed explanation-1: -Adenine always pairs up with Thymine, while Guanine pairs up with Cytosine.
Detailed explanation-2: -The nitrogenous base that is correctly paired is guanine forming a base pair with cytosine.
Detailed explanation-3: -Final answer: In DNA the complementary bases are adenine and thymine, guanine, and cytosine.
Detailed explanation-4: -The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
Detailed explanation-5: -Option A Adenine, thymine-Purines is wrongly matched.
