Question

Quizplus · Accepted Answer

A gene is a segment of DNA that contains the instructions for building a specific protein or a set of proteins. It is smaller than a DNA helix, which is the structure that DNA forms (a double helix). Both a gene and the DNA helix are much smaller than a cell, which is the basic unit of life and can contain many DNA molecules. A zygote, which is a fertilized egg cell, is larger than a single cell because it has the potential to divide and grow into a multicellular organism.
