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: -mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Detailed explanation-3: -Transcription occurs in the nucleus of eukaryotic cells. During transcription, a copy of mRNA is made that is complementary to a strand of DNA.
