Question

Use the following DNA sequence. ATTCCGACCGGG. What is the complementary strand?

1)TUUGGCUGGCCC
2)TAAGGCUGGCCC
3)TUUGGCTGGCC
4)TAAGGCTGGCCC

Answer 1

Answer:4)TAAGGCTGGCCC

Explanation: A complementary strand of DNA is a strand which is not the same as the template strand in base sequence and composition rather a complementary is a strand that has thymine wherever adenine occurs in the template strand and cytosine anywhere guanine is found in the template strand. This means that in DNA base pairing, adenine pairs with thymine while cytosine pairs with guanine.

Answer 2

4)TAAGGCTGGCCC

Step-by-step explanation:

A pairs with T (for DNA strand)

G pairs with C

U is the special nucleobase of RNA and isn't a part of DNA therefore the answer is 4)
