Which of the following best describes the primary function of DNA in cells?
A
It provides energy for cellular processes.
B
It stores genetic information used for the development and functioning of living organisms.
C
It catalyzes biochemical reactions as an enzyme.
D
It acts as a structural component of cell membranes.
Verified step by step guidance1
Understand that DNA (deoxyribonucleic acid) is a molecule found in the cells of all living organisms.
Recall that DNA's main role is related to genetic information, which means it contains the instructions needed for an organism's growth, development, and functioning.
Recognize that DNA does not provide energy for cellular processes; that role is primarily carried out by molecules like ATP (adenosine triphosphate).
Know that DNA itself does not catalyze biochemical reactions; enzymes (which are proteins) perform this function.
Understand that DNA is not a structural component of cell membranes; membranes are mainly composed of lipids and proteins.
