A
UAUCGC
B
CGCTAT
C
TATCGC
D
CGCUAU
Explanation: 

Detailed explanation-1: -Answer and Explanation: The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules. According to these rules, purines always hydrogen bond with pyrimidines and vice-versa.

Detailed explanation-2: -noun Biochemistry. either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases. a section of one nucleic acid chain that is bonded to another by a sequence of base pairs.

Detailed explanation-3: -mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA-adenine (A), cytosine (C), and guanine (G)-are also found in DNA.
