What is the difference between deoxyribose and ribose quizlet?
ribose is a pentose sugar, whereas deoxyribose is a hexose sugar. deoxyribose is found in RNA, whereas ribose is found in DNA. ribose binds a phosphate at the 3′ position, whereas deoxyribose binds a phosphate at the 2′ position. deoxyribose has one less oxygen molecule than ribose.
What is the difference between ribose in RNA and deoxyribose in DNA?
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.
What is the difference between purine and pyrimidine?
A. The purines, adenine and thymine, are smaller two-ringed bases, while the pyrimidines, cytosine and uracil, are larger and have a single ring. The purines, adenine and guanine, are larger and have two a one-ringed structure, while the pyrimidines, thymine and cytosine, have two rings and are smaller.
What is ribose DNA?
Ribose and its related compound, deoxyribose, are the building blocks of the backbone chains in nucleic acids, better known as DNA and RNA. Ribose is used in RNA and deoxyribose is used in DNA. Ribose and deoxyribose are classified as monosaccharides, aldoses, pentoses, and are reducing sugars.
What is the difference between DNA and DNAse?
DNA is a nucleic acid. DNA is deoxyribonucleic acid which is the hereditary material in all organisms except few viruses. DNAse is a deoxyribonuclease, it is an enzyme that catalyzes the hydrolytic cleavage of phosphodiester linkages in the backbone of DNA.
Why is deoxyribose is for DNA and ribose for RNA?
Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.
Is Deoxyribose a purine or pyrimidine?
If the sugar is 2-deoxyribose, the nucleotide is a deoxyribonucleotide, and the nucleic acid is DNA. The nitrogenous bases found in nucleotides are classified as pyrimidines or purines….Table 17.1. 1: Composition of Nucleotides in DNA and RNA.
| Composition | DNA | RNA |
|---|---|---|
| purine bases | adenine and guanine | adenine and guanine |
What is the difference between purine and uric acid?
Uric acid is produced when the body breaks down a chemical called purine. Purine occurs naturally in your body, but it’s also found in certain foods. Uric acid is eliminated from the body in urine.
What is the function of deoxyribose?
Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid. Deoxyribose is a key building block of DNA. Its chemical structure allows for the replication of cells in DNA’s double helix configuration.
Is deoxyribose in DNA or RNA?
DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
What are the 4 main differences between DNA and RNA?
DNA has four nitrogenous bases – Adenine, Guanine, Cytosine and Thyamine. RNA also has four nitrogenous bases, Adenine, Guanine, Cytosine and Uracil.
What is the difference between RNAs and RNase?
The main difference between RNase A and RNase H is that the RNase A is specific for single-stranded RNAs, whereas RNase H is specific for RNA in a DNA: RNA duplex. Furthermore, RNase A produces 2′,3′-cyclic monophosphate intermediates while RNase H produces single-stranded RNA.
How does deoxyribose structurally differ from ribose?
Ribose has its location within the RNA, on the other hand, deoxyribose has its position within the DNA structure. Ribose exists as a normal sugar that has one oxygen atom attached to each carbon atom. On the other hand, deoxyribose exists as a modified sugar and does not have one oxygen atom with the carbon.
Does DNA contain ribose or deoxyribose?
DNA contains deoxyribose nucleotides while RNA contains ribose nucleotides. DNA is more stable than RNA because of the reduction in reactive oxygen atoms. A 5-carbon sugar (ribose or deoxyribose) forms the central molecule in a nucleotide.
What is the chemical structure of deoxyribose?
What is Deoxyribose. Deoxyribose is a pentose monosaccharide or simple sugar with the chemical formula of C5H10O4. Its name specifies that it is a deoxy sugar. It results from the sugar ribose by the loss of an oxygen atom.
