alternating deoxyribose sugar molecules and phosphate groups


What are the sides of the DNA ladder made of?

Deoxyribose, which is a pentose, and a phosphate group. These two molecules together form the two sides of the DNA. A sugar (deoxyribose) and a phosphate.


What forms the sides of the dna ladder-?

The rails (sides) of the ladder are made of alternating sugar and phosphate molecules.


What are the sides of the DNA ladder made up of?

The DNA ladder is made of sugar and phosphates.


What are the sides of the DNA molecule made composed of?

alternating deoxyribose molecules and phosphate groups



3 components of DNA?

The three components of DNA are phosphate, deoxyribose sugar, and nitrogen base. A DNA strand looks like a ladder. The "sides" of the ladder are made up by the phosphates and deoxyribose sugars the "steps" are the nitrogen bases.


What is the backbone or sides of the DNA molecule made of?

PHOSPHATES AND SUGAR The two sides of DNA latter are made up of molecules of a sugar called deoxyribose alternating with molecules known as phosphates


Do the sides of the DNA molecules make up repeating nitrogen bases and sugars?

No. The sides of the DNA molecule is made of alternating deoxyribose sugar molecules and phosphate groups.


What are the two sides of the DNA molecule?

The two sides of DNA latter are made up of molecules of a sugar called deoxyribose alternating with molecules known as phosphates PHOSPHATES AND SUGAR


What parts of the nucleotide make up the rungs of the ladder?

In DNA, the actual nitrogenous base rings make up the "ladder" while the "sides" are made from alternating deoxyribose and phosphate groups.


What are the rungs of a DNA ladder made of?

Deoxyribose (sugar) and Phosphate




The backbone of a DNA molecule is made of which two components?

Phosphate molecules and deoxyribose sugar.


What are the sides of a double helix made of?

Each nucleotide has nitrogen sugar, a hydrogen bond, and on the sides a phosphate and a deoxyribose sugar


What are sides of a double helix made of?

the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose sugar.




Is DNA made of glucose molecules?

No, DNA is composed of: deoxyribose sugar phosphate backbone nucleotide


If the DNA double helix were a twisted ladder what would the sides of the ladder be made of?

The Sides of this ladder equate to the Dna's Sugar-Phosphate Backbone; the Rungs of this ladder equate to the Hydrogen-bonding that takes place between base pairs.


The rings of the DNA ladder are made up of?

DNA is made up of deoxyribose, phosphate, and nitrogen bases (adenine, thymine, cytosine, and guanine). The rungs of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.


What does it mean that DNA is a double helix?

It refers to the DNA molecule that is shaped like a ''twisted ladder'' with the outsides (made of deoxyribose and phoshate) twisted.


Which are attached to the sides or railings of DNA which are made up of?

Rungs are made up of - [nitrogenous bases] Railings are made up of - [deoxyribose and phosphate]


What molecule makes up the sides of a DNA ladder?

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.
