what are 3 major differences between dna and rna?
153315
First of all, the nucleotides of DNA and RNA are different: in DNA, in fact, pentose sugar is deoxyribose, while in RNA it is ribose, which has one more oxygen atom. Moreover, in DNA the nitrogen bases are adenine, cytosine, guanine and thymine while in RNA instead of thymine there is the uracil base.

Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2'-hydroxyl group on the pentose ring (Figure 5). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis.

The DNA is a double-stranded molecule that has a long chain of nucleotides. The RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

DNA- it stores all our hereditary information in the molecule. RNA- copy the DNA so it can be used to make proteins. If we didn't have nucleic acids food, air and information wouldn't get to the cell. If this were to happen the cell would die.

DNA is made up of deoxyribose sugar while mRNA is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded.

There are two types of nucleic acids which are RNA and DNA. They are both mainly composed of monomers of nucleotides. They are both containing a five-carbon sugar backbone which is a phosphate group and a nitrogen base.

The deoxyribose sugar of DNA contains one less oxygen-containing hydroxyl group. DNA is a more stable nucleic acid. RNA, on the other hand, contains a ribose sugar and is more reactive than DNA. Therefore, DNA is a better genetic material than RNA.

There are two primary differences between the two molecules in these terms: ... In terms of the nitrogen bases, which are interchangeable, the DNA molecules use cytosine, guanine, thymine, and adenine (CGTA), whereas RNA uses uracil instead of thymine (CGUA).

RNA is a polymer with a ribose and phosphate backbone and four different bases: adenine, guanine, cytosine, and uracil. The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine.

RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone. How ever structural and functional differences distinguish RNA from DNA. Structurally, RNA is a single-stranded where as DNA is double stranded. DNA has Thymine, where as RNA has Uracil.

Which of these is a difference between a DNA and an RNA molecule? - DNA is a polymer composed of nucleotides, whereas RNA is a polymer composed of nucleic acids. - DNA contains uracil, whereas RNA contains thymine. - DNA is usually double-stranded, whereas RNA is usually single-stranded.

What is the difference in what they do? DNA stores and transmits genetic information. RNA acts as a template for making proteins.

The DNA and RNA Structures Nucleotides simply refer to nitrogenous bases, pentose sugar together with the phosphate backbone. Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

DNA is a double-stranded molecule, while RNA is a single-stranded molecule. ... DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
1443263
RNA and DNA are different because of the presence of the 2'OH on RNA which prevents the ribose sugar from switching from a A-form conformation to a B-form conformation. ... This allows RNA to more frequently form single stranded structured RNA since they are more thermodynamically stable as well as more stable ds-RNA.

(RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell.

DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
