Do covalent bonds join DNA sugar phosphate backbones?
Yes, the sugar and phosphate that make up the DNA backbone are joined together with covalent bonds. These bonds are stronger than the hydrogen bonds which join the bases from different strands together.
The structure of DNA is described as a?
double helix composed of two strands that are twisted together. The strands are made up of nucleotides which consist of a sugar, phosphate group, and a nitrogenous base. This structure allows DNA to store and transmit genetic information.
DNA sugar phosphate backbone?
The sugar-phosphate backbone of DNA refers to the alternating sugar (deoxyribose) and phosphate molecules that link the nucleotides together in a DNA strand. The phosphate group connects the 3' carbon of one sugar to the 5' carbon of the adjacent sugar, forming a stable structure that supports the nitrogenous bases in the double helix. This backbone imparts stability and allows the DNA molecule to twist into its characteristic double helix shape.
Sugar phosphate and a nitrogen base compound make up the DNA molecule?
Yes, DNA molecules are composed of sugar-phosphate backbones and nitrogenous bases. The sugar in DNA is deoxyribose, which forms the backbone with phosphate groups, while the nitrogenous bases (adenine, thymine, cytosine, and guanine) pair up to form the rungs of the double helix structure. This arrangement allows for the storage and transmission of genetic information.
What best describes the structure of a DNA molecule?
A DNA molecule is a double helix structure made up of two strands that are composed of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). The bases on the two strands bond together in a complementary way (A pairs with T, and C pairs with G).
The long backbones of the DNA molecules are made of alternating sugar and?
The sugar-phosphate backbones are the double helix staircase railings.
The sugar-phosphate backbones of the DNA double helix are oriendted in opposite directions this commonly referred to at the?
Antiparallel
A double helix looks like a twisted ladderwhich parts of a twisted ladder are analogoius to the hydrogen bonds and sugar-phosphate backbones if a double helix of DNA?
vagina
What are sides of a double helix made of?
The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.
Which part of the twisted ladder are analogous to the hydrogen bonds and sugar phosphate backbones of a double helix of DNA?
The Nucleotides and the hydrogen bonds.
What best describes the structure of DNA molecule?
A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.
What is the sugar-phosphate supporting structure of the DNA double helix is called?
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
What is the sugar phosphate supporting structure of the DNA double helix called?
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
What molecules form the sides of the double helix?
The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.
What makes up the sides of a double helix?
the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.
What is the supporting structure of the DNA double helix?
The supporting structure of the DNA double helix is called the sugar-phosphate backbone.
What molecules make up the sides of a DNA molecule?
alternating deoxyribose sugar molecules and phophate groups
