Rna contains adenine, guanine, cytosine, and uracil, while dna contains adenine, guanine, cytosine, and thymine Therefore, uracil is the base that distinguishes rna from dna. The four rna bases rna is composed of four distinct nitrogenous bases, categorized into two main groups based on their chemical structure Understand the basic structure of nucleic acids Dna and rna are composed of nucleotides, each containing a sugar, a phosphate group, and a nitrogenous base There are five main nitrogenous bases in nucleic acids
Adenine (a), guanine (g), cytosine (c), thymine (t), and uracil (u). Though both rna and dna contain the nitrogenous bases adenine, guanine and cytosine, rna contains the nitrogenous base uracil instead of thymine Uracil pairs with adenine in rna, just as thymine pairs with adenine in dna Uracil and thymine have very similar structures Uracil is an unmethylated form of thymine. Adenine, guanine, and cytosine are purine bases and are common to both dna and rna
Uracil is found only in rna, while thymine is found only in dna. Ribonucleic acid (rna) is a molecule that is present in the majority of living organisms and viruses It is made up of nucleotides, which are ribose sugars attached to nitrogenous bases and phosphate groups The nitrogenous bases include adenine, guanine, uracil, and cytosine Dna and rna are both made of nucleotides Dna consists of four bases namely adenine, thymine, guanine, and cytosine
On the other hand, rna also consists of four bases namely adenine, guanine, uracil, and cytosine Uracil is the nitrogenous base present in rna, but not in dna The molecular formula of uracil is c 4 h 4 n 2 o 2.
