The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
The phosphate groups and deoxyribose molecules makes up the DNA ladder.
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.
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.
Phosphate and sugar make up the sides of a DNA ladder.
The sugar-phosphate backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate molecules. These molecules form the "rungs" of the DNA ladder, connecting the nitrogenous bases that make up the steps of the ladder.
Heck No!
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
The steps of a DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. The side railing of the ladder is composed of nitrogenous bases (adenine, thymine, cytosine, and guanine) that connect the two strands of the DNA molecule.
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.
The Base Pairs
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.
