Detailed explanation-1: -DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3’ T C G T T C A G T 5’, the mRNA sequence would be 5’ A G C A A G U C A 3’.
Detailed explanation-2: -Except for uracil which replaces thymine in mRNA. A (Adenine) pairs with U (Uracil) instead of Thymine (T) and C (Cytosine) pairs with G (Guanine). Thus, the complementary RNA sequence will be: UAAGCUAC.
Detailed explanation-3: -The sequence of nitrogenous bases in one strand of DNA are 3’ TAC GCG ACG 5’ .
Detailed explanation-4: -mRNA strand is complementary to template strand of DNA, while coding strand has same sequence as RNA (except thymine at the place of uracil). Hence, the sequence of bases in mRNA will be AUUCGAUG.
