Rungs are made up of - [nitrogenous bases]
Railings are made up of - [deoxyribose and phosphate]
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 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.
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.
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.
alternating deoxyribose sugar molecules and phosphate groups
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 sugar-phosphate backbones are the double helix staircase railings.
The DNA ladder is made of sugar and phosphates.
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.
sugar phospate
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.
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.
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.
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.
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.
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.
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.
