A number of women with Phenylketonuria who have been treated since infancy will reach adulthood and become pregnant. If maternal phenylalanine levels are not strictly controlled before and during pregnancy, their offspring are at increased risk for congenital defects and Microcephaly. After birth, these children have severe mental and growth retardation. Pregnancy risks can be minimized by continuing lifelong phenylalanine-restricted diets and assuring strict phenylalanine restriction 2 months prior to conception and throughout gestation.

The citric acid cycle, which takes place in the mitochondria, is the third stage of cellular respiration and it completes the oxidation of glucose. Recall that in glycolysis, glucose is converted to two molecules of pyruvate, and then pyruvate is further oxidized to acetyl CoA. In the citric acid cycle, acetyl CoA is completely oxidized to CO 2 and reduced electron carriers are generated in the form of NADH and another molecule, flavin adenine dinucleotide (FAD) . In addition, ATP is generated through substrate-level phosphorylation. The complete citric acid cycle is illustrated in Figure 4. In this tutorial we will focus on the first and last step, and the products of the citric acid cycle.

During infection, C. diphtheriae expresses a variety of genes that are used to establish infection and cause disease. One of these genes encodes for diphtheria toxin. Expression of the toxin requires the genetic information contained in DNA be converted into protein. The 1st step in this process is transcription, in which DNA is converted into mRNA. The following is a short piece of the DNA sequence for diphtheria toxin (written 5’ to 3’): TAA GCG TAG AAC TTG. Which of the following sequences represents the mRNA (written 5’ to 3’) that will be generated from this DNA sequence?

Amplification generally means an addition to or expansion of a statement or idea. In medical terminology, amplification refers to the selective copying of a gene or any sequence of DNA. This occurs naturally in the body in order to satisfy the increased requirement of individual cells for gene products such as proteins. Amplification also plays a role in cancer cells when a tumour cell copies DNA segments as a result of cell signals or external environmental factors. Artificial amplification is conducted due to its central role in gene research.
