Chapter 10, Problem 10SA
Summary Introduction
Introduction:
The change in the external and internal environment of a cell, allows the cell to respond. It is critical for life to respond to the change. The response of a cell changes the time and rate of gene expression. In flowers, the floral identity genes are homeotic genes.
