What type of cell is Deoxyribonucleic acid?

  1. a. Dehydration

  2. b. Decibel

  3. c. Desalination

  4. d. A kind of nucleic acid

The correct answer is: d. A kind of nucleic acid

Deoxyribonucleic acid, commonly known as DNA, is indeed a kind of nucleic acid. Nucleic acids are biopolymers essential for all forms of life and are primarily responsible for the storage and transmission of genetic information. DNA specifically encodes the instructions needed to build and maintain an organism, making it fundamental to biological inheritance. Understanding DNA’s structure is crucial; it is composed of nucleotides, each containing a sugar (deoxyribose in this case), a phosphate group, and a nitrogenous base. This composition allows DNA to store genetic information in the sequence of these bases. The functional properties of DNA enable it to replicate and pass on genetic traits when cells divide, highlighting its essential role in biology. The other options provided do not relate to DNA at all. Dehydration refers to the removal of water, decibels are a unit of measurement for sound intensity, and desalination is the process of removing salt from water, none of which pertain to the classification or characteristics of DNA as a nucleic acid.
