Multiple Choice

Which statement best summarizes the role of the DNA molecule in cells?

DNA stores and transmits genetic information necessary for the development, functioning, and reproduction of living organisms.

DNA directly synthesizes proteins without any intermediary molecules.

DNA acts as a structural component of cell membranes.

DNA provides energy for cellular processes by breaking down into ATP.

Verified step by step guidance

Understand the fundamental role of DNA in cells by recalling that DNA contains the instructions needed for an organism's growth, development, and reproduction.

Recognize that DNA does not directly synthesize proteins; instead, it serves as a template for RNA, which then guides protein synthesis.

Recall that DNA is not a structural component of cell membranes; cell membranes are primarily composed of lipids and proteins.

Know that DNA itself does not provide energy for cellular processes; energy is supplied mainly by molecules like ATP, which are produced through cellular respiration.

Conclude that the best summary is that DNA stores and transmits genetic information necessary for the development, functioning, and reproduction of living organisms.
