The DNA double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?
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.
What is structure of DNA?
DNA is a double helix structure made up of nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). The bases pair together in a complementary manner (A with T, C with G) to form the rungs of the DNA ladder.
Which part of DNA is double helix?
The whole DNA strand is a double helix.
Describe the 3 dimensional structure of DNA?
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.
Diagram of DNA?
A DNA molecule has a double helix structure composed of two strands that are twisted around each other. The sides of the ladder-like structure are made up of alternating sugar and phosphate molecules, while the rungs are formed by pairs of nitrogenous bases (adenine-thymine and cytosine-guanine). DNA carries genetic information in the sequence of these nitrogenous bases.
What structures form the rungs of the DNA double helix?
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.
What shape is DNA?
DNA is a double helix, or a twisted ladder.
The DNA double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?
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.
What are the four nitrogen bases that make up the rungs of the double helix?
In DNA, the four bases are: adenine, guanine, thymine and cytosine.
What kinds of bonds hold the bases together to create the rungs of DNA?
"There are four bases, adenine, guanine, cytosine, and thymine, in DNA. The bases give DNA their variety. The bases are the "rungs" in the double helix ladders and the "handles"of the double helix are composed of deoxyribose sugar and phosphate. Hydrogen bonds hold all of these components together."

what is the shape of a DNA?
double helix
Does DNA have bases on the interior of the double helix?
Yes, DNA bases are located on the interior of the double helix structure. The bases pair up with each other across the two strands of DNA to form the rungs of the DNA ladder-like structure. This base pairing is crucial for maintaining the integrity and functioning of the DNA molecule.
What is the double coiled shape of DNA?
A molecule of DNA consists of two strands of various chemical compounds that other chemicals carrying genetic information join together, much like ladder rungs hold ladder rails apart. The two strands joined with thousands of rungs look like a long rope ladder that has been twisted into the shape of a spiral, called a double helix.
Which part of DNA is double helix?
The whole DNA strand is a double helix.
What makes up the rungs of the DNA ladder?
The rungs of the DNA ladder are made up of nitrogenous bases, specifically adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.

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.
