Question

Substances common in DNA and RNA is:
A: Hexose sugar
B: Histamine
C: Thymine
D: Phosphate group

Answer 1

Hint: Large biomolecules, such as nucleic acids are needed for all known forms of life. They are made up of nucleotides, which are three-component monomers consisting of a \[5\]-carbon sugar, a phosphate group, and a nitrogenous base. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two primary types of nucleic acids (RNA). Nucleic acids are naturally occurring chemical compounds that make up the genetic material and function as the main information-carrying molecules in cells. Nucleic acids are abundant in all living organisms, where they make, encode, and store knowledge for every living cell in every life form on the planet.

Complete answer:
Option A:
Deoxyribose is the pentose sugar in DNA, while ribose is the pentose sugar in RNA. The sugars are distinguished by the presence of a hydroxyl group on the second carbon of ribose and hydrogen on the second carbon of deoxyribose.
So, option A is incorrect.
Option B:
Histamine is a nitrogenous organic compound that plays a role in local immune responses, as well as controlling gut physiological activity and functioning as a neurotransmitter in the brain, spinal cord, and uterus. Histamine is a key mediator of itching and plays a part in the inflammatory response.
So, option B is incorrect.
Option C:
A nucleotide is made up of a sugar molecule bound to a phosphate group and a nitrogen-containing base. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases used in DNA (T). The nucleotide uracil (U) replaces thymine in RNA.
So, option C is incorrect.
Option D:
Phosphoric acid and deoxyribonucleosides are used to make deoxyribonucleotides. Phosphoric acid and ribonucleosides make up ribonucleotides. The sugar content of deoxyribonucleosides and ribonucleosides differs, as do the nitrogenous bases that are present. Phosphoric acid is a common component of both deoxyribonucleotides and ribonucleotides.
So, option D is correct.

Hence, Option D is the correct answer.

Note:
Nucleic acids are divided into two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The inheritance and transmission of unique characteristics from one generation to the next is regulated by DNA and RNA. The transfer of inherent characteristics from parent to offspring is mediated by nucleic acids.
They are in charge of protein synthesis in our bodies, and forensic scientists use DNA fingerprinting to determine paternity. It's also used to track down and identify suspects. It has also played a significant role in biological evolution and genetics research.
