The potential toxicity of dietary nucleic acids to humans usually arises not from the nucleic acids but
What elements make up nucleic acids?
The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
What are the names of the four nucleotides?
They are:
- Nitrogenous bases – Purine and Pyrimidine
- Pentose Sugar – Ribose and Deoxyribose
- Phosphate – monophosphate, diphosphate, triphosphate
What is the name of the molecule that contains nitrogenous bases?
Adding more phosphate groups makes a nucleoside di- and tri-phosphate, and so on. Nucleotides have nitrogenous bases of two kinds, purine or pyrimidine. In RNA, the 5-carbon sugar group is called ribose, and in DNA the 5-carbon sugar is deoxyribose.
What is the name of the chemical that takes the DNA code and uses it to make proteins?
RNA. RNA (ribonucleic acid) are the nucleic acids that take the code form DNA and use it to construct proteins. In other words, they are the biological machinery that extracts the genetic code from the DNA and executes the instructions. Like DNA, strands of RNA are made of polynucleotide chains.
What is the basic genetic code of an organism?
DNA . DNA (deoxyribonucleic acid) is the molecule that contains the basic genetic code of an organism. Molecules of DNA contain purine and pyrimidine nucleotide bases. The purine bases are adenine and guanine (A and G) while the pyrimidine bases are cytosine and thymine (C and T).
What are the strands of polynucleotide called?
Assemblies of polynucleotide strands are called nucleic acids, DNA and RNA. Nucleotides are extremely important because they serve as the fundamental bits of information in DNA, analogous to the binary 1 and 0 of a digital computer.
How do nucleotides bond?
Nucleotides bond to form polynucleotide chains. These polynucleotide chains form by a dehydration reaction, in which the sugar in one nucleotide is bonded to the phosphate group of another and a water molecule is removed. These phosphodiester linkages are what form the sugar-phosphate backbone of strands of DNA and RNA.
What are the strands of RNA made of?
Like DNA, strands of RNA are made of polynucleotide chains. Unlike DNA, RNA molecules exist as single strands that loop back on themselves. RNA also uses a different set of nitrogenous bases than DNA. RNA contains 3 bases found in DNA, adenine, guanine, and cytosine.
What are the building blocks of DNA and RNA?
Nucleotides are the basic building blocks of DNA and RNA, two molecules essential for life as we know it. Molecules of both DNA and RNA serve as the genetic code that uniquely identifies every living organism. One can think of DNA and RNA as sets of instructions that guide the construction of proteins and the cellular organization of the body.

These elements bind to form monosaccharides, phosphate groups, and nucleobases, otherwise known as nitrogenous bases. In both RNA and DNA the phosphate group is the same form, but there are differences in ...
What are the elements of a nucleic acid?
Nucleic Acid Elements and Monomer. Nucleic acids are biocompounds, which are essential for living organisms. Found in two forms— deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)—these polymer chains are composed of the same basic elements and similar monomer nucleotides, yet with specific differences relating to form and function.
What is the backbone of sugar phosphate?
The combination of ribose or deoxyribose and phosphate group forms the sugar-phosphate backbone. The nitrogenous base is attached to the sugar molecule. The addition of a phosphate group to the nucleoside created by sugar and nitrogenous base forms a nucleotide.

In RNA, adenine pairs with uracil and guanine with cytosine. The following images show the chemical structure of each type of monomer, where the pentagonal shape of the monosaccharide and its attached phosphate group and specific nucleobase are clearly defined.
What are the elements that make up a nucleic acid chain?
The five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus. The addition of phosphorus makes nucleic acid different to other categories of biocompounds, namely carbohydrates, lipids, and proteins.
How many nitrogen atoms are in a single ringed form of DNA?
Single ringed forms, known as pyrimidines, contain between two and three nitrogen atoms and are smaller and shorter. This is important in the double-strand feature of DNA and the process of translation, as only certain pairings of nitrogenous bases are possible (Watson-Crick pairings).
Can adenine and guanine bond?
This also tells us that adenine and guanine cannot create a double-strand bond together. In RNA, other base combinations are possible and are known as non-Watson-Crick pairings. In Watson-Crick pairings, larger bases, adenine, and guanine will never pair with each other.
What are nucleic acids?
Regina Bailey. Updated January 25, 2020. Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.

What is the genetic code for a bundle of nucleotides?
Genetic code: A bundle of three nucleotides encodes one amino acid (trinucleotide or three nucleotides, not three base pairs). After the end of transcription, an mRNA is formed which only has the long chain of nucleotide monomer that encodes amino acids. All the non-coding sequences are removed.
What are the properties of nucleic acid?
Properties of nucleic acid: 1 It is acidic in nature. It accepts paired electrons and donates protons. 2 The nucleic acid is overall negatively charged due to the presence of a negative charge on the backbone of it. 3 It does not have its own color or odor. 4 The nucleic acid is insoluble in alcohol thus can be precipitated using it. It can also be precipitated using HCl or acetic acid. 5 It can be easily dissolved in hot water. 6 DNA is a double-stranded and antiparallel molecule so DNA is more stable than RNA.
