what are three differences between rna and dna?
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.

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 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).
589433
DNA and RNA structure are similar because they both consist of long chains of nucleotide units. ... (1) RNA is single-stranded while DNA is a double-stranded helix. (2) RNA also has uracil as its base while the DNA base is thymine.

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.

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. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

Terms in this set (6) DNA is stable under alkaline conditions while RNA is not stable. RNA directly codes for amino acids and as acts as a messenger between DNA and ribosomes to make proteins. RNA uses adenine, uracil, cytosine, and guanine.
1086535
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.

RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).

DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.

Answer is : 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.

The DNA is a double-stranded molecule, while the RNA is single-stranded- formed from the DNA during transcription. Based on that, another difference between both is that the DNA polymerase manufacture double-stranded DNA while the RNA polymerase manufacture a single-stranded RNA.

Which of these is a difference between a DNA and an RNA molecule? DNA contains nitrogenous bases, whereas RNA contains phosphate groups. DNA contains five-carbon sugars, whereas RNA contains six-carbon sugars. DNA is a polymer composed of nucleotides, whereas RNA is a polymer composed of nucleic acids.
1340471
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.

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.

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.

Summary of Differences Between DNA and RNA DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable.
