When nucleotides polymerize to form a nucleic acid What happens?
Nucleotides polymerize to produce nucleic acids through formation of a phosphodiester linkage between the phosphate group on the 5′ carbon of one nucleotide and the – OH group on the 3′ carbon of another ( Figures 4.2 and 4.3 ).
How do nucleic acids polymerize?
Polymerization of Nucleotides (Phosphodiester Bonds) Nucleotides are joined together similarly to other biological molecules, by a condensation reaction that releases a small, stable molecule. The 3′ hydroxyl group forms a bond to the phosphorus atom of the free nucleotide closest to the 5′ oxygen atom.
Nucleotides are joined together to form nucleic acids through the phosphate group of one nucleotide connecting in an ester linkage to the OH group on the third carbon atom of the sugar unit of a second nucleotide.
What converts nucleic acids to nucleotides?
Converting nucleotides to deoxynucleotides
Nucleotides are initially made with ribose as the sugar component, which is a feature of RNA. DNA, however, requires deoxyribose, which is missing the 2′-hydroxyl (-OH group) on the ribose. The reaction to remove this -OH is catalyzed by ribonucleotide reductase.
What are the three main components nucleotides?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
How are nucleotides formed?
A nucleotide is formed from a carbohydrate residue connected to a heterocyclic base by a β-D-glycosidic bond and to a phosphate group at C-5′ (compounds containing the phosphate group at C-3′ are also known). The molecules derived from nucleotides by removing the phosphate group are the nucleosides.
What are the 3 components of nucleic acids?
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
What are examples of nucleic acids?
Examples of Nucleic Acids
- deoxyribonucleic acid (DNA)
- ribonucleic acid (RNA)
- messenger RNA (mRNA)
- transfer RNA (tRNA)
- ribosomal RNA (rRNA)
What is the main function of nucleic acids?
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
What are the two main types of nucleic acids?
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals.
Are nucleotides acidic or basic?
Nucleotides are formed by nucleosides(sugar and nitrogenous group) + phosphate group. This phosphate group provides dna with acidic nature. Phosphate group (PO4^-3) presents in DNA, that’s makes the DNA acidic.
What is the difference between nucleic acids and nucleotides?
Explanation: Nucleotides are the monomers that make up a nucleic acid, such as DNA or RNA. Nucleic acids are made of long strands of nucleotides and are an essential part of every living thing.
Where are nucleic acids found?
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.
How are nucleotides broken down?
Nucleotides are the building blocks of nucleic acids – deoxyribonucleic acid, or DNA – and ribonucleic acid, or RNA. The most basic structure of the nucleotide can be broken down into three subunits – a five carbon sugar, a phosphate group, and a nitrogenous base, also known as nucleobase.
How is nucleic acid broken down?
RNA and DNA are hydrolized by the pancreatic enzymes (ribonucleases, deoxyribonucleases) into nucleic acids, which are further broken down to purine and pyrimidine bases and pentoses, by enzymes in the intestinal mucosa (nucleases).
