The one which is present in all living things is ___________?
Correct answer: B. DNA or RNA
- A. Cell nucleus
- B. DNA or RNA
- C. Cell membrane
- D. Vacuole
Explanation
All cellular organisms possess genetic material, either DNA or, in some biological systems, RNA, which stores or transmits hereditary information. The likely alternative is cell nucleus, but prokaryotes lack a membrane-bound nucleus and mature red blood cells also lack one.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.

Jameel identifies Gram-positive and Gram-negative bacteria by using the Gram staining technique. After the completion of the whole procedure, he observed under the microscope that the Gram-positive bacteria were stained purple (violet) and Gram-negative bacteria were red (pink) in colour.The reason for this difference in staining is that the cell wall of Gram-positive bacteria contains a layer that retains in staining.This layer is composed the purple crystal violet stain
