Which nitrogen base sequence is the partner of t-c-a-g-c-a

Option (C) is the correct answer.

Explanation:

According to Watson and Crick DNA base pairing, purine bind to the pyrimidine base whereas each purine binds to a particular type of pyrimidine.

Like adenine (A) binds with thymine (T) and guanine (G) binds with cytosine (C) in a DNA molecule.

Since, the given sequence is T-C-A-G-C-A, therefore, its nitrogen base sequence is A-G-T-C-G-T.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
