One of the primary differences between DNA and RNA is that DNA is double-stranded while RNA is single-stranded. Table of Contents. Difference; DNA. Structure; Types; RNA. RNA Types; Proteins; Frequently Asked Questions; Read on to explore the DNA and RNA differences in detail.
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 :
DNA and RNA also have different structures; DNA's phosphate-sugar backbone contains deoxyribose, while RNA's contains ribose. While DNA is double-stranded and has the nitrogenous bases adenine, thymine, cytosine, and guanine, RNA is usually single-stranded and contains uracil instead of thymine.
Dec 18, 2020 · They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two 1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA.
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.
Jan 9, 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.
