Detailed explanation-1: -DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
Detailed explanation-2: -The actual coding of the mRNA transcript is very straightforward. DNA contains four bases: adenine (A), thymine (T), guanine (G) and cytosine (C). Since DNA is double-stranded, the strands hold together where the bases pair. A always pairs with T, and G always pairs with C.
Detailed explanation-3: -mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA-adenine (A), cytosine (C), and guanine (G)-are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine.
Detailed explanation-4: -In RNA, uracil pairs with adenine.
