by weak hydrogen bonds :)
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 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 bases of DNA form the rungs of the ladder structure, which is often depicted as a twisted double helix. Each rung consists of two nitrogenous bases paired together—adenine with thymine, and cytosine with guanine—held together by hydrogen bonds. The sugar-phosphate backbone forms the sides of the ladder, providing structural support to the molecule.
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.
each side of the chromosome is called a chromatid they are bonded together by the centromere
what holds the sides of the DNA ladder together
The two sides are formed by the four bases, Adenine, Guanine, Thymine and Cytosine. Adenine on one side of the ladder would pair with Guanine on the corresponding ladder. The same goes for Cytosine and Thymine.
The rungs on a ladder are held between the rails.
The sides of the ladder are made up of alternating deoxyribose sugar and phosphate molecules. The steps or rungs of the ladder are made up of nitrogenous bases held together by hydrogen bonds.
Oh, dude, it's like the nucleotides are the building blocks of DNA, right? So, the sides of the DNA ladder are made up of sugar and phosphate molecules bonded together. It's like the backbone of the whole DNA structure, holding it all together.
The DNA is in the shape of a double helix, two strands twisted together like a ladder. The sides of the ladder is made up of the sugar phosphate portions of the adjacent nucleotides bonded together. The phosphate of one nucleotide is covalently bonded to the sugar of the next nucleotide. The nitrogenous bases on either sides of the DNA stands join together to form the rung of the ladder. Each base pair is formed from complimentary nucleotides, purines with pyramidines bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine.
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.
Phosphate and sugar make 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.
The two sides of the DNA double helix ladder are made up of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The nitrogenous bases on opposite strands pair together through hydrogen bonding (adenine with thymine, and guanine with cytosine), holding the two sides of the ladder together.
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.
The sides of the DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules, linked together in a chain. These sugar-phosphate backbones provide the structural support for the DNA molecule.
