Detailed explanation-1: -Answer and Explanation: Yes, all organisms on the Earth use the same 5 nitrogenous bases. DNA contains adenine, thymine, guanine, and cytosine while RNA contains adenine, uracil, guanine, and cytosine.
Detailed explanation-2: -Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
Detailed explanation-3: -With some minor exceptions, all living organisms on Earth use the same genetic code. This means that the codons specifying the 20 amino acids in your cells are the same as those used by the bacteria inhabiting hydrothermal vents at the bottom of the Pacific Ocean.
Detailed explanation-4: -The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C). Base pair may also refer to the actual number of base pairs, such as 8 base pairs, in a sequence of nucleotides.
