Which macromolecule has a sugar phosphate backbone
Which macromolecule has a sugar-phosphate backbone quizlet?
The sugar-phosphate backbone of RNA is made up of the sugar ribose. In addition, RNA uses a nitrogenous base called uracil in place of thymine. Like thymine, uracil is complementary to adenine.
What has a sugar-phosphate backbone?
DNA
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Where is sugar and phosphate backbone found?
DNA
The ‘sides’ of the ladder (or strands of DNA) are known as the sugar-phosphate backbone. This backbone consists of alternating phosphate and sugar groups, with the sugar molecule of one nucleotide linking to the phosphate group of the adjacent nucleotide.
What macromolecule contains sugar phosphate and nitrogenous base?
nucleotides
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
Which of the following macromolecule is composed of monomer units containing A sugar A phosphate group and A nitrogenous base?
nucleic acids
Biological molecules that are composed of monomer units containing sugar, a phosphate group, and a nitrogen-containing base are nucleic acids.
What bonds hold the sugar-phosphate backbone together?
The bond formed between the sugar of one nucleotide and the phosphate of an adjacent nucleotide is a covalent bond. A covalent bond is the sharing of electrons between atoms. A covalent bond is stronger than a hydrogen bond (hydrogen bonds hold pairs of nucleotides together on opposite strands in DNA).
What is the sugar backbone of DNA?
deoxyribose
Explanation: DNA stands for “deoxyribonucleic acid.” The backbone of DNA is comprised of alternating sugar and phosphate units, in which the sugar is deoxyribose. The backbone of RNA is also comprised of sugar and phosphate units, but uses the sugar ribose.
What type of bonds hold the sugar-phosphate backbone together?
The sugar phosphate backbone has sugar rings, each with 5 carbons and an oxygen, that are held together by phosphodiester bonds.
Which type of bond connects the sugar-phosphate backbone of DNA quizlet?
the sugars and phosphates create the backbone by covalently bonding: sugar-phosphate-so that connects up one strand. the strand binds to another strand by hydrogen bonding between the nitrogenous bases on each strand, which form pairs (A and T, C and G).
What type of bonds hold the phosphate sugar backbone of DNA together quizlet?
Sugar-Phosphate Backbone forms a covalent bond called a phosphodiester bond. It binds a phosphate group of one nucleotide to a 5 carbon sugar of another. These bonds create one strand. Base pairs are bonded with hydrogen bonds (AT, GC – purines to pyrimidines).
Which of the following is used to form covalent bonds in the sugar-phosphate backbone between fragments of DNA?
Phosphodiester bonding
Phosphodiester bonding between nucleotides forms the sugar-phosphate backbone, the alternating sugar-phosphate structure composing the framework of a nucleic acid strand (Figure 3).
What is the sugar-phosphate backbone of DNA quizlet?
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. Enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription.
What forms the backbone of DNA?
Phosphate Backbone
Phosphate Backbone
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. 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.
Where are the sugar-phosphate backbones and the nitrogenous bases located in the DNA double helix quizlet?
The coiled sugar-phosphate backbones are on the outside of the double helix. In DNA’s double helix, are the nitrogenous base pairs on the inside or the outside? The nitrogenous base pairs are on the inside of the double helix.
What is a sugar-phosphate backbone quizlet?
Sugar-Phosphate Backbone. a chain of sugars and phosphates in DNA and RNA; the sugar of one nucleotide bonds to the phosphate of the next nucleotide in a DNA or RNA strand.
Does the sugar-phosphate backbone of the DNA stores genetic information?
The sugar phosphate backbone of the DNA stores genetic information. DNA replication occurs after interphase. The two strands of each polynucleotide chain in DNA are identical. After replication of a DNA molecule is completed, two molecules are present: the original DNA and a newly synthesized DNA.
What is the key to the linking of nucleotides that form the sugar-phosphate backbone of DNA?
The sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH2 group that is attached to a phosphate ion.
What is guanine quizlet?
guanine. One of the four bases found in DNA and RNA. Guanine is a purine; it pairs with cytosine. deoxyribose. The sugar component of DNA nucleotides, having one fewer hydroxyl group than ribose, the sugar component of RNA nucleotides.
What forms the backbone of DNA chain quizlet?
The deoxyribose and the phosphate groups form the backbone of the nucleic acid molecule.
What makes up the DNA backbone quizlet?
The backbone is comprised of alternating pairs of Sugars (Deoxyribose) and Phosphate groups. The rungs of DNA are comprised of pairs of Nitrogenous Bases. These bonds hold the nitrogen bases together.
