What stores and transmits genetic information?
Understand the Problem
The question is asking about the biological components that are responsible for the storage and transmission of genetic information. This typically refers to DNA (deoxyribonucleic acid) and its role in heredity and cellular functions.
Answer
DNA (deoxyribonucleic acid)
The molecule that stores and transmits genetic information in the cell is deoxyribonucleic acid (DNA).
Answer for screen readers
The molecule that stores and transmits genetic information in the cell is deoxyribonucleic acid (DNA).
More Information
DNA is composed of two strands that form a double helix. It contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
Tips
A common mistake is to confuse proteins or lipids as the genetic information carriers. Always remember that nucleic acids, specifically DNA (and RNA in some organisms), are responsible for storing and transmitting genetic information.
