Nucleotides are monomers that join together to form the structural units of RNA and DNA, as well as providing an energy source in metabolism. (C), Guanine (G), Adenine (A), Thymine (T), and Uracil (U).
What are the 3 main functions of nucleic acids?
The three main functions of nucleic acids are gene expression and regulation of cellular activities, storage and transmission of genetic information.
What are two main function of nucleic acid?
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What are 4 functions of nucleic acids?
Nucleic Acids
The fact that they form the chemical basis for the transmission of genetic traits was not realized until 1941. Among other important roles, nucleotides can serve as sources of energy in the form of ATP, physiological signaling mediators, secondary messengers, and allosteric enzyme effectors.
What is the main function of nucleic acids Brainly?
The main function of nucleic acids is to store and transmit genetic information and use that information to direct the synthesis of new protein.
What is nucleic acid and its function Class 12?
Nucleic acids are the polymers in which nucleotides are monomers. These are biomolecules present in nuclei of all living cells in the form of nucleoproteins . They are also called as polynucleotides .
Why is nucleic acid an acid?
The only difference there is the replacement of two of the protons from the phosphoric acid with protons from the sugar molecules of the nucleotide. This leaves only one remaining proton, which is very acidic. That easily-lost proton is what causes nucleic acids to be so acidic.
What is nucleic acid in chemistry?
Nucleic acids are long-chain polymeric molecules, the monomer (the repeating unit) is known as the nucleotides and hence sometimes nucleic acids are referred to as polynucleotides. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two major types of nucleic acids.
What are the specific functions of proteins and nucleic acids in our body?
Nucleic acid is important in storing, transmitting, and making useful the information necessary for the processes of life.
What is the importance of DNA and RNA?
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life.
What functional groups are in nucleic acids?
Nucleic acid—one phosphate group, one nitrogen containing base (pyrimidine or purine) and a sugar molecule, which in turn has alcohol and aldehyde/ketone group.

What are nucleic acids 9?
Nucleic acids are long-chain polymeric molecules.
Where are nucleic acids?
It is found in all cells and also in some viruses. Nucleic acids have a very diverse set of functions, such as cell creation, the storage and processing of genetic information, protein building, and the generation of energy cells.
Why are nucleotides strong acids?
Simply put, nucleotides are acidic. The presence of phosphate groups in nucleic acids causes them to be acidic in nature. The easily-lost proton found in them is the reason why nucleic acids are acidic.
Which is an important component of protein and nucleic acids?
Answer. Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
Where do nucleic acids come from?
Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
How are nucleic acids used in medicine?
“Nucleic acid medicines” utilize “nucleic acid,” which refer to substances such as DNA and RNA that control genetic information, as drugs.
Are proteins made of monosaccharides?
Proteins formed by a linear combination of. amino acids monomers (among 20) by. peptide linkage.
Carbohydrates formed by linear or. branched combination of monosaccharides. monomers by glycosidic linkage.
Lipids form large structures but the. interactions are not covalent. Non polar and. amphiphatic molecules.
What are nucleic acids anatomy and physiology?
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.
Which statement is true about nucleic acids?
Correct answer:
Nucleic acids are made up of nucleotides that contain a pentose sugar, a phosphate group, and a nitrogenous base. There are two types of nucleic acids; DNA and RNA. The difference between these two nucleic acids is their pentose sugar. DNA has deoxyribose whereas RNA has ribose sugar residues.
What is the function of the lipid bilayer in a cell membrane?
The lipid bilayer is a universal component of all cell membranes. Its role is critical because its structural components provide the barrier that marks the boundaries of a cell. The structure is called a “lipid bilayer” because it is composed of two layers of fat cells organized in two sheets.
What are three functions of lipids?
Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules.
What is the function of lipids in plants and animals?
Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and mammals dry because of their hydrophobic nature.
What are the major functions for each macromolecule type in the human body?
Nucleic acids: Stores and transfers info.
Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall.
Lipid: Insulator and stores fat and energy.
Protein: Provide structural support,transport, enzymes, movement, defense.
What determines the function of a molecule?
The Three-Dimensional Structure of Biological Macromolecules Determines How They Function. It is the three-dimensional shape of proteins and nucleic acids that endows them with their biological activities.
Why can nucleic acids be found in nearly every food?
All living things are made of cells. All cells come from pre-existing cells by transmitting nucleic acids from the parent cell to the new cell. That means that every food that we derive from a living thing is chock full of nucleic acids in every one of its cells.

What is nucleotide by BYJU’s?
A nucleotide is an organic molecule with a basic composition of a nitrogenous base, pentose sugar and phosphate. DNA and RNA are polynucleotides, which contain a chain of nucleotides monomers with different nitrogenous bases. Nucleotides are essential for carrying out metabolic and physiological activities.
What is the importance of nucleic acid metabolism?
Nucleic acid metabolism generates and hydrolyzes DNA and RNA molecules and their components in the cell, in the processes of DNA replication, repair, recombination and turnover of DNA, transcription of RNA on DNA, and purine and pyrimidine synthesis and breakdown
What is RNA vs DNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Can RNA turn into DNA?
For the first time, scientists have found evidence that polymerase theta can write RNA segments back into DNA. Scientists at Thomas Jefferson University, US, have provided the first evidence that RNA segments can be written back into DNA.
Do nucleic acids have amino groups?
Nucleic Acid: Nucleic acid is a complex organic molecule such as DNA or RNA, made up of many nucleotides linked in a long chain. Amino Acid: Amino acid is a simple organic molecule, which contains both carboxyl and amino groups.
What is the role of nucleic acid in the formation of proteins?
Nucleic acids are involved in protein synthesis. The specific sequence of bases in DNA indicates coded instructions to manufacture particular proteins. Information in the DNA is passed to another nucleic acid in the process, which is called messenger RNA. It exits the nucleus for the cytoplasm of the cell.
