Question

if one dna strand reads atcccgag, the other strand will be made up of the complementary bases
a tagggctg
b tacccgtc
c atgggctc
d tagggctc

Explanation:

Step1: Recall base - pairing rules

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

Step2: Find complementary bases for each base in the given strand

The given strand is ATCCCGAG.

• For A (first base), the complementary base is T.
• For T (second base), the complementary base is A. But wait, no, hold on. Wait the base - pairing is A - T and T - A, C - G and G - C.

The strand is ATCCCGAG. Let's do it base by base:
A (1st) pairs with T, T (2nd) pairs with A (no, wait original strand is ATCCCGAG. Wait the correct way:
Original strand: A T C C C G A G
Complementary bases: T A G G G C T C

Answer:

d. TAGGGCTC
