What are chemical properties of nucleic acids?
Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
What are the two 2 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. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria.
What are nucleic acid give two examples?
Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.
What are the chemical structures and functions of nucleic acids?
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
What are the chemical compositions of nucleic acids?
A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
What are the chemical properties of proteins?
Proteins – Physical & Chemical Properties
- Colour and Taste. Proteins are colourless and usually tasteless.
- Shape and Size. The proteins range in shape from simple crystalloid spherical structures to long fibrillar structures.
- Molecular Weight.
- Colloidal Nature.
- Denaturation.
- Amphoteric Nature.
- Ion Binding Capacity.
- Solubility.
What is the chemical formula for nucleic acid?
Deoxyribonucleic acid | C15H31N3O13P2 – PubChem.
What are 2 functions of nucleic acids?
Definition. Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.
What are the chemical composition of DNA and RNA?
Both DNA and RNA contain – purine type nitrogenous bases of adenine (abbreviated A) and guanine (G) and pyrimidine type cytosine (C). Apart from that, DNA has a second pyrimidine called thymine (T), whereas RNA has a thymine analogue called uracil (U).
What are the chemical properties of amino acids?
General Properties of Amino Acids:
- They have a very high melting and boiling point.
- Amino acids are white crystalline solid substances.
- Amino acids are sweet, tasteless, and bitter in taste.
- Most of the amino acids are soluble in water and are insoluble in organic solvents.
What is the physical and chemical properties of proteins?
Amphoteric Nature Like amino acids, the proteins are amphoteric, i.e., they act as acids and alkalies both. These migrate in an electric field and the direction of migration depends upon the net charge possessed by the molecule. The net charge is influenced by the pH value.
What are the chemistry of nucleotides?
Nucleotides are composed of phosphoric acid, a pentose sugar (ribose or deoxyribose), and a nitrogen-containing base (adenine, cytosine, guanine, thymine, or uracil). Ribonucleotides contain ribose, while deoxyribonucleotides contain deoxyribose.
What are the 3 chemical components of a DNA nucleotide?
The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).
What are the chemical substances of DNA?
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
What are the physical and chemical properties of acid?
Chemistry
| Property | Acid | Base |
|---|---|---|
| Taste | Sour (vinegar) | Bitter (baking soda) |
| Smell | Frequently burns nose | Usually no smell (except NH3!) |
| Texture | Sticky | Slippery |
| Reactivity | Frequently react with metals to form H2 | React with many oils and fats |
What are chemical properties of proteins?
Proteins usually are almost neutral molecules; that is, they have neither acidic nor basic properties. This means that the acidic carboxyl ( ―COO−) groups of aspartic and glutamic acid are about equal in number to the amino acids with basic side chains.
What are the three chemically distinct components in a nucleotide?
A nucleotide has three chemically distinct components – a heterocyclic compound, a monosaccharide and phosphoric acid or phosphate.
Which property is found in nucleosides and nucleotides?
_____ Which property is found in nucleosides and nucleotides? a) Both contain a nitrogenous base, a pentose, and at least one phosphate group.
What chemicals are found in a nucleotide?
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).
What is the list of chemical components of DNA?
DNA has three chemical components: (deoxyribose) sugars, phosphate groups, and nitrogenous bases.
Which 2 chemical compounds make up a chromosome?
DNA and histone proteins are packaged into structures called chromosomes.
What is an example of a nucleic acid?
Examples of Nucleic Acids. The most common nucleic acids in nature are DNA and RNA. These molecules form the foundation for the majority of life on Earth, and they store the information necessary to create proteins which in turn complete the functions necessary for cells to survive and reproduce.
What are the physico-chemical properties of nucleic acids?
In this article we will discuss about the physico-chemical properties of nucleic acids. The size of nucleic acids varies immensely. The smallest ribonucleic acids are the tRNAs which comprise about 80 nucleotides; their molecular weight is about 30 000.
