How would the deoxyribose sugar phosphate back bone of nucleotide chains look if purines paired only with purines and pyrimidines paired only with pyrimidines?

Watson thought of that as possible when he was under a misapprehension as to the structure of the nucleotides ( he thought enol when it was keto ). The backbone would be kinked and crooked, not smooth and seamless as it truly is.

Are there amino acids in nucleic acids?
No. Nucleic acids are formed by a sugar (ribose or deoxyribose), a phosphate group and nitrogen base (purines and pyrimidines).
What is the structure of a nucleotide in a DNA molecule?
A nucleotide consists of three components: 1. A 5-carbon sugar (deoxyribose for DNA or ribose for RNA) 2. A nitrogenous base (adenine, cytosine guanine and thymine (or uracil in RNA) 3. A phosphate group
What are the components of a nucleotide?
A pentose sugar (ribose or deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil).
What are the three molecules of a nucleotide?
A nucleotide is composed of a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), a ribose sugar (ribose or deoxyribose), and a number of phosphates (1 to 3).
How are the 3 parts of a nucleotide attached to one another?
its all because of eggsthat's why"Sugar(Deoxyribose), Nitrogenous Base, and a phosphate group.They are connected by covalent bonds."
How do purines differ from pyrimidines?
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
Which one is purines and pyrimidines are bigger?
Purines because purines have two rings where as pyrimidines have only one ring.
What are the 3 major groups of chemicals in DNA?
What are the 3 major groups of chemicals in DNA? DNA is made up of three basic chemical components: Phosphate. Deoxyribose (a sugar). Two Pyrimidines Cytosine and Thymine. Two Purines Guanine and Adenine.
How is Presence of purines and pyrimidines in DNA found?
Adenine and Guanine are purines, and Thymine and Cytosine are pyrimidines.
What are nuclei acids made of?
Each nucleotide consists of a sugar in the middle of a phosphate group and a nitrogenous base .There are two classes of bases. Two are purines (double-ringed structures) and two are pyrimidines (single-ringed structures).Very basically, they are made of a nitrogen base, a pentose (5 carbons) sugar and a phosphate group.
Purines and pyrimidines are?
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
What do purines bond to?
Purines bond to pyrimidines in nucleic acid DNA .
