DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine :
Aug 23, 2020 · Three differences between DNA and RNA are that DNA uses the base thymine while RNA uses uracil, DNA uses the sugar deoxyribose while RNA uses ribose, and usually DNA is double-stranded and RNA is single-stranded.
Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.

Jan 22, 2021 · Although DNA and RNA share many similarities, there are several key structural and functional differences between these two molecules. DNA vs. RNA. What Are Nucleic Acids? DNA and RNA are both types of nucleic acids, which are large molecules found in all living cells and viruses. Nucleic acids are the information-carrying molecules of the cell.
Oct 11, 2019 · Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
The nucleic acids, DNA and RNA, may be thought of as the information molecules of the cell. In this section, we will examine the structures of DNA and RNA, and how these structures are related to the functions these molecules perform.
Sep 9, 2024 · The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.
RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found...
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are complex molecular structures that control all hereditary characteristics of cells and thus of organisms. DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms.
