Detailed explanation-1: -The sequence of the mentioned DNA strand is 5’-ATCAGC-3’. So, the sequence of the complementary strand will be 3’-TAGTCG-5’.
Detailed explanation-2: -Each end of DNA molecule has a number. One end is referred to as 5’ (five prime) and the other end is referred to as 3’ (three prime). The 5’ and 3’ designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
Detailed explanation-3: -If one strand of a DNA molecule has the sequence of bases 5’ATTGCA3’, the other complementary, antiparallel strand of DNA would have the sequence: 5’TGCAAT3’.
Detailed explanation-4: -So, the sequence of the complimentary strand in 5’ to 3’ direction is 5’-GCATGCATGCATGCATGCATGCATGCAT− 3’.
