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: -Final answer: The sequence of mRNA produced by 3’ ATCGGTTAAC 5’ template strand, 5’ TAGCCAATTG 3’ stretch of DNA in coding strand will be 3’ GUUAACCGAU 5’.
Detailed explanation-3: -Explanation: The template strand of DNA has AAA sequence, which will be transcribed to mRNA as UUU.
Detailed explanation-4: -Transcription of DNA template strand by RNA polymerase produce RNA transcript which have a sequence complementary to the template strand. A template with “ATG” will code a RNA transcript with triplet “UAC".
