Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.
UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:
- A base (adenine)
- T base (thymine)
- G base (guanine)
- C base (cytosine)
The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.

Molecules that are present in the membranes of gram-negative bacteria and are the best-known pamps are called Bacterial lipopolysaccharides (LPSs).
Bacterial lipopolysaccharides (LPS) are the primary outer surface membrane elements present in almost all Gram-negative bacteria and it act as extremely strong stimulators of the innate or natural immunity in the diverse eukaryotic species ranging from insects to humans.
Eukaryotes are the organisms whose cells contain a nucleus and other membrane-bound organelles. eukaryote, any cell or organism that possesses a clearly defined nucleus. The first eukaryotic cells was evolved about 2 billion years ago. In this Cells with nuclei surrounded by a nuclear envelope with nuclear pores.

Answer:
Their cell walls are composed of very different biochemicals.
Explanation:
Biological classification is important to classify the organisms on the basis of their similarities and differences between them. Linnaeus is known as the father of biological classification.
Cellwall plays an important role in the maintenance of structure and function of the organisms. The composition of the cell wall of fungi, plants and prokaryotes are quite different. Plants cell wall made of cellulose, fungi has chitin in its cell wall and prokaryotes has different layers of cell wall.
Thus, the correct answer is option (D).
