Is DNA a sugar or protein?
DNA vs. RNA – 5 Key Differences and Comparison
| Comparison | DNA |
|---|---|
| Structure | DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. |
What is the sugar in a DNA nucleotide?
deoxyribose
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
What type of sugar does nucleotides have?
Each nucleotide subunit is composed of a pentose sugar (deoxyribose), a nitrogenous base, and a phosphate group. The two strands associate via hydrogen bonds between chemically complementary nitrogenous bases.
What is the sugar called in a DNA molecule?
Fundamentals of Molecular Genetics. DNA consists of a pair of chains of a sugar-phosphate backbone linked by pyrimidine and purine bases to form adouble helix (Fig. 96.1). The sugar in DNA is deoxyribose.
Is DNA a protein?
No, DNA is not a protein. The major relationship between DNA and protein is that DNA encodes the information that is necessary to synthesize proteins. But DNA itself is not a protein. DNA is composed of long chains of nucleotides.
Is DNA a protein or carbohydrate?
The correct answer is D. DNA is a polymer. DNA, or deoxyribonucleic acid, is a nucleic acid consisting of two antiparallel chains of nucleotides that… See full answer below.
What kind of sugar is found in a nucleotide quizlet?
Nucleotides are the building blocks of nucleic acids. Deoxyribose is the sugar molecules found in DNA. They have one less oxygen atom than ribose sugar which is found in RNA. The backbone of the DNA is made up of phosphate and deoxyribose.
Is nucleotide a carbohydrate lipid or protein?
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Monomer |
|---|---|---|
| Proteins | CHON −NH2 + −COOH +R group | Amino acids |
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Fatty acid and glycerol |
| Carbohydrates | C:H:O 1:2:1 | Monosaccharides |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | Nucleotides |
Where are the sugars in DNA?
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3′ end, and the phosphate is the 5′ end of each nucleiotide.
What is in the nucleotide?
A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
Is DNA a nucleic acid or a protein?
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms.
Is a DNA a protein?
Is DNA made of protein?
What is DNA made of? DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
What nucleotides make up a nucleotide?
Listen to pronunciation. (NOO-klee-oh-tide) A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
Which of the following is part of a nucleotide sugar amino acid proteins DNA?
Answer and Explanation: The correct answer is C. Amino acid. An amino acid is not a component of nucleotide.
Is DNA A protein?
Is sugar A carbohydrate lipid or protein?
Simple carbohydrates: Various forms of sugar, such as fructose (fruit sugar) and sucrose (table sugar), are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy.
Is DNA made of sugars?
DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).
What are the nucleotides in DNA?
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
What is DNA made of?
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
