Sugar phosphate backbones do not include the nucleic acids of the DNA. They are composed of a sugar and a phosphate group bonded to each other.

Are the phosphate groups on the interior or exterior of the DNA molecule?

The phosphate groups are on the exterior of the DNA molecule. They form the backbone of the DNA molecule and are involved in binding to other molecules in the cell.


Is it true that DNA has two sugar phosphate backbones and variable sequences of nitrogenous bases that form complementary pairs between the sugar-phosphate backbones?

True


If the DNA molecule reresents a twisted ladder which chemical units form the sides of the ladder?

The sides of the DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules, linked together in a chain. These sugar-phosphate backbones provide the structural support for the DNA molecule.


What substances make up the side of the DNA ladder?

The sides of the DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. These sugar-phosphate backbones run along the outside edges of the DNA molecule, providing structural stability.


What molecules make up the sides of a DNA molecule?

alternating deoxyribose sugar molecules and phophate groups


The long backbones of the DNA molecules are made of alternating sugar and?

The sugar-phosphate backbones are the double helix staircase railings.


What is found in the sides of DNA molecules but not on the rungs?

In a DNA molecule, the sides are made up of alternating sugar and phosphate groups bonded together. These sugar-phosphate backbones provide structural support to the DNA molecule. The rungs of the DNA ladder are made up of nitrogenous bases that form hydrogen bonds between complementary base pairs.


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.


How many sugar phosphate backbones does a double helix have?

A double helix structure has two sugar-phosphate backbones, one on each side of the helix. These backbones are made up of alternating sugar and phosphate molecules that support the DNA bases in the helix.


Is the backbone of a DNA molecule made up of phosphate molecules and deoxyribose sugars?

Yes, you are correct. DNA is made up of a base (adenine, thymine, cytosine and guanine), a phosphate and a deoxyribose Sugar. The phosphate and the sugar form the backbone while the bases form the links in between


How are the backbones of DNA held together?

The backbones of DNA are held together by covalent bonds, specifically phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the sugar group of another nucleotide, creating a strong polymer structure that makes up the backbone of the DNA molecule.


What forms the sides of DNA ladder?

The sides of the DNA ladder are formed by alternating sugar and phosphate molecules. These sugar-phosphate backbones run parallel to each other on opposite sides of the double helix structure of the DNA molecule.
