when auxin binds to its receptor is the activation of a select group of transcription factors. The activated transcription factors enter the nucleus and promote the expression of specific genes. Genes whose expression is stimulated by the activation of pre-existing transcription factors are called primary response genes or early genes.
a) Some of the early genes encode proteins that regulate the transcription of secondary response genes, or late genes, that are required for the short-term responses to the hormone
b) Early genes are involved in intercellular communication, or cell-to-cell signaling and some also involved in adaptation to stress
c) Secondary response genes are required for the long-term responses to the hormone. Because late genes require de novo protein synthesis, their expression can be blocked by protein synthesis inhibitors
d) Early-gene expression can also be blocked by inhibitors of protein synthesis such as cycloheximide, the time required for the expression of the early genes can be quite short, ranging from a few minutes to several hours
Which of the following is the correct prediction about primary response gene?
