Why does the DNA backbone not line up at each end?
The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the "sides" of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the "rungs" of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
In the ladder like model of DNA the sides upright consists?
The upright sides of the ladder-like model of DNA consist of alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the DNA molecule. The sugar-phosphate backbone provides structural support and stability to the DNA molecule.
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.
The rungs or steps of DNA are made up of nitrogenous bases deoxyribose phosphatewhich are attached to the sides or railings of DNA which are made up of?
The sides or railings of DNA are made up of alternating sugar (deoxyribose) and phosphate molecules, forming the backbone of the DNA molecule. The rungs or steps of DNA are made up of nitrogenous bases (adenine, thymine, cytosine, and guanine) which form hydrogen bonds to connect the two strands of the DNA molecule in a complementary manner.
What makes up the sides orbackbone ofa DNA molecule?
Alternating deoxyribose and phosphate molecules.
What makes up the rail or sides of the DNA structure?
Backbone. A deoxyribose sugar and a phosphate group.
What sugar makes up the backbone for DNA?
deoxyiribose.

What type of sugar makes up the backbone of the DNA molecule?
Deoxyribose sugar makes up the backbone of the DNA molecule. This sugar is a type of pentose sugar that forms the repeating units along the DNA strand.
What makes up the back bone of a DNA molecule?
Deoxyribose sugars and phosphates make up the backbone of DNA.
What 2 substances make up the backbone or the sides of the DNA molecule?
The backbone of DNA is made up of sugar molecules called deoxyribose and phosphate groups, which alternate along the sides of the DNA molecule.
What makes up the sides of the DNA ladder?
Phosphate and sugar make up the sides of a DNA ladder.
What makes up the sides of a DNA molecule?
A DNA molecule consists of two strands that are made up of sugar (deoxyribose) and phosphate molecules. The sides of the DNA molecule are formed by alternating sugar and phosphate molecules linked together to create a backbone for the molecule.
What makes up the outside of the dna ladder?
The outside of the DNA ladder is made up of a sugar-phosphate backbone. The sugar in DNA is deoxyribose, which alternates with phosphate groups to form the backbone. The nitrogenous bases are attached to this sugar-phosphate backbone on the inside of the ladder.
What makes up the sides of the ladder of a DNA molecule?
The sides of a DNA molecule are made up of alternating sugar molecules (deoxyribose) and phosphate groups that form the sugar-phosphate backbone. Each sugar molecule is connected to one of four nitrogenous bases (adenine, thymine, cytosine, or guanine) that extend inward from the backbone and pair with a complementary base on the opposite strand.
What makes up the sides of the ladder a DNA molecule?
The backbone of the DNA molecule is made up of a sugar (deoxyribose) bonded to a phosphate group bonded to another sugar and then another phosphate and so on. These are very strong covalent bonds that are not easily broken.
What molecules make up the sides of the DNA ladder?
The sides of the DNA ladder are made up of sugar-phosphate backbones. The sugar in DNA is deoxyribose, linked together by phosphate groups forming the backbone of the DNA strand.
