So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose. These two are almost identical and work together in order for cell to grow. They both are nucleic acids but RNA is only a single-stranded one compared to DNA. Second, they are compose of different kinds of sugar. RNA has ribose sugar while DNA has deoxyribose sugar. RNA is required to make proteins, yet proteins are involved in the production of RNA. DNA has "blueprint" for these intertwined environment for them to work smoothly and continue to replicate new cells. This structural differences is amazing yet, it teaches us a lot about life: it was designed by an intelligent designer and does not come by chance as some people presumes and theorizes.

Although DNA and RNA both carry genetic information, there are quite a few differences between them. This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences. Summary of Differences Between DNA and RNA
Comparison of DNA and RNAWhile both DNA and RNA are used to store genetic information, there are clear differences between them. This table summarizes the key points:
Which Came First?There is some evidence DNA may have occurred first, but most scientists believe RNA evolved before DNA. RNA has a simpler structure and is needed in order for DNA to function. Also, RNA is found in prokaryotes, which are believed to precede eukaryotes. RNA on its own can act as a catalyst for certain chemical reactions. The real question is why DNA evolved if RNA existed. The most likely answer for this is that having a double-stranded molecule helps protect the genetic code from damage. If one strand is broken, the other strand can serve as a template for repair. Proteins surrounding DNA also confer additional protection against enzymatic attack. Unusual DNA and RNAWhile the most common form of DNA is a double helix. there is evidence for rare cases of branched DNA, quadruplex DNA, and molecules made from triple strands. Scientists have found DNA in which arsenic substitutes for phosphorus. Double-stranded RNA (dsRNA) sometimes occurs. It is similar to DNA, except thymine is replaced by uracil. This type of RNA is found in some viruses. When these viruses infect eukaryotic cells, the dsRNA can interfere with normal RNA function and stimulate an interferon response. Circular single-strand RNA (circRNA) has been found in both animals and plants. At present, the function of this type of RNA is unknown. Additional References
What is the structural difference between DNA and RNA?DNA and RNA are different from their structure, functions, and stabilities. DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can't.
What is one difference between the structure of DNA and RNA Brainly?DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring.
What are the structural difference between DNA and RNA Class 12 chemistry?DNA has a double helix structure. RNA has a single helix structure. The nitrogenous bases present in DNA are Adenine, Guanine, Thymine, and Cytosine. The nitrogenous bases present in RNA are Adenine, Guanine, Uracil, and Cytosine.
Which of the following nitrogenous bases is found in DNA but not in RNA Brainly?Thymine is in DNA. DNA have thymine, guanine, adenine and cytosine. Thymine is replaced by uracil in RNA.
