In this lesson we will describe how changes in the gene can alter the gene expression process and influence traits in an organism. The specific example of ALS-inhibitor herbicide resistance is used to demonstrate the impact of genetic change on trait expression in a plant.

In the other half of the cells that go through meiosis, the tetrads will line up so that the ‘E’ genes will be passed on with the ‘b’ genes and the ‘e’ genes will go with the ‘B’ genes.

The row and column from steps 1 and 2 intersect in a set of boxes in the codon table, one half containing four codons and the other half containing the mapped amino acid(s). If you want to use the structure of the table to the maximum, however, you can use the third axis (on the right side of the table) corresponding to the intersect box.

The power of rDNA technology comes from our ability to study and modify gene function by manipulating genes and transform them into cells of plant and animals. To arrive at this several tools of molecular biology are used including, DNA isolation and analysis, molecular cloning, quantification of gene expression, and many others.

The impact that a single gene’s information can have on an organism, however, is tremendous. Furthermore, organisms have all their genes in each of their cells, but they only need to use the information from a subset of these genes, depending on the type of cell and the cell’s stage of development. Therefore, the key to gene function is controlling its expression.

In the case of our ALS protein, the assembly of all 667 amino acids into the polypeptide or protein chain in the correct order is important because the sequence of the amino acids determines how the protein folds.

This lesson describes how a PCR reaction works, what it accomplishes, and its basic requirements for success. Examples of interpreting results are given. PCR’s strengths, weaknesses, and applications to plant biotechnology are explained.
