Summary Introduction

Introduction:

DNA is made up of sugar-phosphate backbone, including nitrogenous bases. The two chains are parallel to each other but oriented in opposite directions. The nitrogenous bases are paired with hydrogen bonds.

Answer to Problem 1MCQ

Correct answer:

In the complementary strand of DNA (Deoxyribonucleic Acid), adenine (A) binds with thymine (T), and cytosine (C) binds with guanine (G). Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as “TAACAGG.”

The given sequence is ATTGTCC. A pairs T and G pairs with C; thus, TAACAGG should be the sequence of the complementary strand.

Reason for incorrect answer:

Option b. is given as, “ACCTCGG.”

The sequence is incorrect except the A which is present in the first place. Hence, option b. is incorrect.

Option c. is given as, “CGGAGTT.”

The given sequence CGGAGTT is incorrect as T is present C, A is with G, G is with T, and so on. This sequence is violating the Chargaff rule. Hence, option c. is incorrect.

Option d. is given as, “CCTGTTA.”

In this particular option, the sequence given is wrong as A binds with C, T is with C, T is with T, and so on. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

T should be paired with A and G should be paired with C. Hence, according to this rule correct sequence should be TAACAGG. Thus, the correct answer is option a.
