Guanine is a nitrogenous base found in both DNA and RNA. Which of the following is an alternative name for guanine?
DNA sequencing, therefore, is the use of methods and technologies to determine the identity and order of the four nucleotide bases (adenine, guanine, cytosine, and thymine) in a segment of DNA. Top The importance of sequencing The three-dimensional, double-helical structure of DNA was ...
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). Although nucleotides derive their names from the nitrogenous bases they contain, they owe much of their structu...
based on crystallographic data produced by Rosalind Franklin and Maurice Wilkins. A key feature of the Watson–Crick model was the two strands, each a linear polymer of nucleotides. This model later led to revelations about how the composition and order of the nitrogenous bases of the nucleotides...
a) cytosine b) thymine c) guanineNitrogenous Bases:Nitrogenous bases are structures that form part of nucleotides that make up nucleic acids such as DNA and RNA. Nitrogenous bases are categorized into purines and pyrimidines.Answer and Explanation: The nitrogenous ...
DNA is a long string of these blocks or letters. Each nucleotide consists of a sugar (deoxyribose) bound on one side to a phosphate group and bound on the other side to a nitrogenous base. There are two classes of nitrogen bases called purines (double-ringed structures) and pyrimidines (...

<p>To solve the question, "A nitrogenous base is present in RNA but absent in DNA. Identify it," we can follow these steps:</p><p>1. <strong>Understand Nucleotides</strong>: Nucleotides are the building blocks of nucleic acids, which include DNA and RNA.
Nitrogenous Bases: Nitrogenous bases (also known as nucleobases) are the components of the deoxyribonucleic or ribonucleic acid, where they link with a pentose sugar (ribose or deoxyribose) and a phosphate group to form a structure called a nucleotide, which forms the backbone of the deoxyribonuclei...
