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.


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

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


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

The DNA ladder is made of sugar and phosphates.


What makes up the sides of a DNA strand?

A DNA strand is made up of alternating sugar (deoxyribose) and phosphate molecules. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules, forming the "rungs" of the DNA ladder.


what are the sides of the DNA ladder made of?

sugar phospate


What makes up the side of the ladder of a DNA molecule?

The sides of a DNA molecule are made up of alternating sugar (deoxyribose) and phosphate molecules, forming the backbone of the DNA strand. The bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules and form the rungs of the ladder structure through hydrogen bonds.


What is the molecules that make the upright of a DNA?

The backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate molecules. The bases adenine, thymine, guanine, and cytosine are attached to the deoxyribose sugars, forming the rungs of the DNA helix.


What 2 molecules make up the sides of the DNA molecule?

The two molecules that make up the sides of the DNA molecule are deoxyribose sugar and phosphate groups. These molecules alternate to form the sugar-phosphate backbone of the DNA double helix structure.


Is the sides of the DNA molecule are made up of repeating nitrogen bases and sugars?

The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.


What are the sides of dna are made up of?

DNA is made up of two strands that are composed of nucleotides. Each nucleotide consists of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The two strands of DNA are held together by hydrogen bonds between complementary nitrogenous bases.


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.


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.
