Detailed explanation-1: -Solution : (c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.
Detailed explanation-2: -In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).
Detailed explanation-3: -The reverse complement of a DNA sequence is formed by reversing the letters, interchanging A and T and interchanging C and G. Thus the reverse complement of ACCTGAG is CTCAGGT. What is a genome?
Detailed explanation-4: -The complementary mRNA sequence to the DNA strand TGCCAT will contain the bases A, C, G, and U (instead of T). In addition, the mRNA sequence will contain the bases that complement the bases in the DNA strand. Therefore, the complementary mRNA base sequence will be: ACGGUA.
Detailed explanation-5: -If one strand of DNA is CGGTAC, the corresponding strand would be: E. GCCATG. We can determine this due to the complementary base pairing that occurs in DNA: C base pairs with G, and A base pairs with T.
