Question

Which of the following nucleotide sequences represents the complement to the DNA strand 5' -AGATCCG- 3' ?

A) 5' -AGATCCG- 3'
B) 3' -AGATCCG- 5'
C) 5' -CTCGAAT- 3'
D) 3' -CTCGAAT- 5'
E) 3' -TCTAGGC- 5'

Answer 1

The complement to the DNA strand 5' -AGATCCG- 3' is 3' -TCTAGGC- 5', which follows the base pairing rules of A with T and C with G.

Step-by-step explanation:

The DNA strand 5' -AGATCCG- 3' has a complementary strand that can be deduced by following the base pairing rules, where adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, for the given DNA strand 5' -AGATCCG- 3', its complementary strand will read as 3' -TCTAGGC- 5', which means that the correct answer to the student's question is option E)
