Question

5 directions: drag the nitrogenous bases to the correct locations on the image. each base can be used more than once, but not all bases must be used. a section of a dna molecule is shown in the diagram below, but only one strand is complete. add the correct nitrogenous bases to the molecule to form two complementary dna strands.

Explanation:

Step1: Recall DNA base - pairing rules

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Step2: Analyze the given DNA strand

The given DNA strand is T - G - C - T - C - A - G - A - C - T.

Step3: Determine the complementary bases

For T, the complementary base is A; for G, it is C; for C, it is G; for A, it is T.
The complementary strand will be A - C - G - A - G - T - C - T - G - A.

Answer:

A - C - G - A - G - T - C - T - G - A
