N2 - The previous chapter described how changes in the environment are perceived at the cellular level and how this perception is transduced into a cellular response. Cellular responses to stimuli can lead to long-lasting functional changes, which generally occur via regulation of the expression of specific genes. The characteristic features of each cell, tissue and organism are in fact the results of distinctive gene expression. Thus, the knowledge of how gene expression is regulated is fundamental for the understanding of all biological functions. Many studies in the last 50 years have shown that transcription and translation are essential for behavioral responses including learning and memory as well as in long-term plasticity in general. Here we will discuss these two key mechanisms of gene expression, DNA transcription and RNA translation, and will particularly focus on how in the nervous system they mediate long-term memory formation.

The C proteins bound to and associate with one another causing the DNA between them to form a loop effectively blocking transcription of the operon.

Gene expression and protein levels

Adaptation to specific environments is achieved by regulating the expression of genes that encode the enzymes and proteins needed for survival in a particular environment.

Histone proteins and rRNA are needed in large quantities by almost all eukaryotic cells therefore the genes encoding histones and rRNA exist in a permanently amplified state.

A very small portion of the protein makes contact with the DNA through H-bonds and van der Waals interactions between amino acid side chains and the functional groups in the major groove and the phosphate backbone of the DNA.

This kit is intended for teaching students in a practical course doing experiments related to gene expression and protein synthesis.
The "Protein Expression Reagent Kit" provides sufficient reagents to conduct one "Cell-Free Protein Synthesis Course" for 20 students. In the experimental outline, it is assumed that two students perform the experiments together, and therefore reagents are provided for 10 groups/sets of experiments.
During this "Cell-Free Protein Synthesis Course", experiments are performed to demonstrate both steps of protein biosynthesis: Transcription of an mRNA from a DNA template and translation of the mRNA into a functional protein. The kit provides a DNA template for the expression of a Green Fluorescent Protein, or "GFP", that can easily be detected by exhibiting bright green light upon exposure to blue or ultraviolet light. Visibility of the green light proves that a functional protein had been prepared during the "Cell-Free Protein Synthesis Course".
Specific instrumentation for doing the experiments can be purchased separately as a "Laboratory Instrument Set".
