The Double helix is actually made of repeating units called nucleotides
The rungs of the DNA double helix are made up of alternating deoxyribose sugar molecules and phosphate molecules. Please refer to the related link below.
The twisted ladder shape of DNA is called a double helix.carbohydrate
double helix, twisted ladder, spiral staircase.
The sugar-phosphate backbones are the double helix staircase railings.
A double helix structure has two sugar-phosphate backbones, one on each side of the helix. These backbones are made up of alternating sugar and phosphate molecules that support the DNA bases in the helix.
The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.
the whole strand is called a double helix a individual molecule made up of... a sugar a phosphate a base is called necleotide.
The smallest structure among the options provided is the double helix, which is the structure of DNA at its core. The double helix consists of two strands of nucleotides wound around each other in a helical shape. The other structures mentioned - chromosome, supercoil, and nucleosome - are made up of multiple DNA molecules or DNA-related proteins and are larger in comparison.
The backbone of a nucleic acid is made up of alternating sugar and phosphate molecules bonded together to these are attached the molecule making the rungs of the double helix ladder the Nucleotides.
DNA has two polynucleotide molecules that spiral around an imaginary axis to form a double helix. only certain bases in the double helix are compatible with each other. Adenine pairs with thymine and guanine pairs with cytosine.
The backbone of the double helix is primarily made up of sugar (deoxyribose) and phosphate molecules. These molecules are alternated along the DNA strand, forming a sugar-phosphate backbone that provides structural stability to the DNA molecule.
