DNA stands for Deoxyribonucleic acid and is the blueprint for the human body. The shape is a double helix it looks like a twisted latter, each foot step in the "ladder" is made up of protein. There are four types of proteins: Guanine, Adenine, cytosine, and thymine. Guanine pairs with cytosine and adenine pairs with thymine. The pairs extend from each "step in the ladder" on opposite sides to connect and form a trait. This makes up you. Also DNA is only individual to one person, except for identical twins and clones.
DNA is arranged in a double helix structure, where two strands of nucleotides are twisted around each other. The nucleotides are composed of a sugar-phosphate backbone with nitrogenous bases adenine pairing with thymine and guanine pairing with cytosine. This arrangement allows for genetic information to be stored and replicated accurately.
DNA is composed of many nucleic acids bound by covalent and hydrogen bond. The five carbon sugar(deoxyribose) attached to the phosphate group is joined to one another to form the sides of the DNA, forming a covalent bond of sugar-phosphate-sugar-phosphate etc. Also, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other. The purines(double ringed base) which are A and G bond with the pyrimidines T and C respectively. The bonding between the two creates a hydrogen bond. Together with all these reactions, DNA is formed and looks like a twisted ladder, or a double helix.
DNA is constructed of two long polynucleotide strands wound together in a right-handed double helix. Each nucleotide is formed of a sugar (2-deoxyribose), a phosphate group, and a nitrogenous base, which will be either adenine, guanine, cytosine, or thymine. Adenine and guanine are purines, meaning they have a double ring structure and four nitrogens. Cytosine and thymine are pyrimidines, which have a single ring structure and only two nitrogens. A purine is always paired with a pyrimidine, when the DNA is found in its stable double-stranded state, and the pairings are always adenine with thymine and cytosine with guanine. Adenine and thymine form two hydrogen bonds, while cytosine and guanine form three.
DNA strands have a 5' end and a 3' end. The 5' end is characterized by a phosphate group coming off of the fifth carbon in the sugar. The 3' end exhibits an OH group protruding from the third carbon of the sugar. The strands always pair anti-parallel to one another in the double helix, meaning that the 3' end of one strand will be on the same end as the 5' end of the other. Finally, the double helix structure creates alternating major and minor grooves within the helix.
the phosphate group grow two small glands called binary testicals and then inserts a rod like shaft into the center of the membrane on the sugar molecules and have sexual reproductiong producing dna

What are chains of chemicals arranged like rungs on a twisting ladder?
DNA molecules consist of chains of nucleotides arranged like rungs on a twisting ladder, forming the double helix structure. The nucleotides in DNA are made up of a phosphate group, a sugar molecule, and a nitrogenous base. The arrangement of these nucleotides determines the genetic information stored in the DNA molecule.
What is a polynucleotide?
A polynucleotide is a polymer made up of nucleotide monomers linked together by covalent bonds. These polymers serve as the basic structural unit of DNA and RNA molecules.
What molecules consists of a string nucleotides of nitrogenous base deoxyribose and phosphate groups?
DNA molecules consist of a string of nucleotides composed of a nitrogenous base (adenine, thymine, cytosine, or guanine), deoxyribose sugar, and phosphate groups. These nucleotides are arranged in a double helix structure, forming the genetic code of an organism.
What are essential molecules of DNA?
The essential molecules of DNA are nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides are arranged in a specific sequence to form the double helix structure of DNA, which carries genetic information in living organisms.
Genes are arranged on twisted strands called what?
Genes are arranged on twisted strands called chromosomes.

How do you describe the basic structure of the DNA molecules?
DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.
What do you mean by crystaline?
Crystalline means that the molecules are arranged in a specific pattern. Amorphous means that the molecules are arranged randomly.
What are chains of chemicals arranged like rungs on a twisting ladder?
