Do nucleic acids carry chemical energy?
Do nucleic acids carry chemical energy?
Explanation: Nucleic acids are a type of macromolecules that make up the genetic material. This is their main function. Unlike the other three macromolecules (carbohydrates, lipids, and proteins), nucleic acids are not used for energy production; therefore, the results stated in this question don’t seem valid.
Why nucleic acids are not used as energy source?
Nucleic acids cannot perform energy storage functions because it can hamper the genetic code they contain during the continuous metabolic mechanisms of the synthesis of energy.
Which of the following is not an example of a nucleic acid?
Answer and Explanation: The correct answer is c. Fatty acid group. The fatty acid group is not a part of a nucleic acid.
Are nucleotides sources of chemical energy?
They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP) and uridine triphosphate (UTP)—throughout the cell for the many cellular functions that demand energy, including: amino acid, protein and cell membrane …
Are nucleic acids a fuel?
Nucleic Acids. They differ from other nutrients in that they are not a source of energy in your diet. Their only role is to direct the synthesis of new protein molecules.
What are 5 chemical properties of nucleic acids?
Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). A and G are categorized as purines, and C, T, and U are called pyrimidines.
What is bad about nucleic acids?
Elevated blood levels of extracellular nucleic acids have been reported in various disease conditions; such as ageing and age-related degenerative disorders, cancer; acute and chronic inflammatory conditions, severe trauma and autoimmune disorders.
What are nucleic acids 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 non examples of acid?
Examples of nonaqueous acids are sulfur trioxide, aluminum chloride, and boron trifluoride. Compare base.
Do nucleotides store energy?
In nucleotides like ATP, the energy is stored in the phosphoanhydride bonds between the three phosphate groups. These bonds require energy to form, so the cells in your body can use these bonds like a battery to store extra power.
Are nucleotides used for energy?
Other Functions of Nucleotides. Adenosine Triphosphate (ATP) is the primary energy currency of cells. ATP is derived from an adenine nucleotide. The second and third phosphate groups are attached by high energy bonds that are relatively unstable.
Are proteins a source of energy?
The body needs protein to maintain and replace tissues and to function and grow. Protein is not usually used for energy. However, if the body is not getting enough calories from other nutrients or from the fat stored in the body, protein is broken down into ketone bodies to be used for energy.
What is nucleic acid example?
What is the chemical properties of nucleic acid?
Nucleic acids are 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 chemical compositions of nucleic acids?
Nucleic acids such as DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) are composed of a sugar or derivative of a sugar (ribose or 2-deoxyribose), a nucleobase (cytosine, guanine, adenine, thymine, or uracil), and phosphoric acid and found in cell nuclei.
Is nucleic acid poisonous?
Mutant ribonucleic acid (RNA) molecules can be toxic to the cell, causing human disease through trans-acting dominant mechanisms.
Can you live without nucleic acids?
Without DNA, living organisms could not grow. Further, plants could not divide by mitosis, and animals could not exchange genes through meiosis. Most cells simply wouldn’t be cells without DNA.
Which one of the chemical substances is not in DNA deoxyribonucleic acid?
So, the correct option is ‘Uracil’.
What are nucleic acids in chemistry?
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What substance is the chemical opposite of an acid?
Bases. A base is chemically opposite to an acid. Some bases dissolve in water and are called alkalis.
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 functions of nucleic acids?
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ).
What nucleic acids contain nitrogen bases?
Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). A and G are categorized as purines, and C, T, and U are collectively called pyrimidines. All nucleic acids contain the bases A, C, and G; T, however, is found only in DNA, while U is found in RNA.
What are the elements in nucleic acids?
The elements in all nucleic acids include carbon, hydrogen, oxygen, nitrogen, and phosphorus. The most common types of nucleic acids are: Note that all of these acids end in “NA,” which stands for “nucleic acid.” They are made up of five pieces, or monomers: guanine (G), cytosine (C), thymine (T), uracil (U), and adenine (A).
