HUMAN NUTRITION

Detailed explanation-1: -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 (Figure 3).

Detailed explanation-2: -One of the four nucleobases in DNA’s nucleic acid, represented by the letters G-C-A-T, is thymine. This is so that the DNA repair enzymes may recognize thymine rather than uracil. Because thymine has a higher resistance to photochemical mutation and makes the genetic code more durable, DNA uses it instead of uracil.

Detailed explanation-3: -RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.

Detailed explanation-4: -Nucleic Acids: DNA and RNA Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U).
