Question
What is the complementary strand of DNA created from the template strand 3’ CTCGGAACTTA 5’? [B.2G]Select one:a.5’ GAGCCTTGAAT 3’b.5’ GAGGGAACTTTA 3’c.5’ CTCGGAACTTA 3’d.5’ CUCGGAAGUUA 3’
Solution
The complementary strand of DNA is created by pairing the bases of the template strand with their counterparts: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
The template strand given is 3’ CTCGGAACTTA 5’.
To find the complementary strand, we pair the bases as follows:
- C pairs with G
- T pairs with A
- C pairs with G
- G pairs with C
- G pairs with C
- A pairs with T
- A pairs with T
- C pairs with G
- T pairs with A
- T pairs with A
- A pairs with T
So, the complementary strand is 5’ GAGCCTTGAAT 3’.
Therefore, the correct answer is a. 5’ GAGCCTTGAAT 3’.
