| Gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. This article aims to describe the regulatory mechanisms that control gene expression in both eukaryotes and prokaryotes. | |
|
| Deletion mapping allows geneticists to answer several questions about a specific gene. It can determine where a deleted region of a gene is located, whether this deletion affects only the area in which the gene deletion occurs, and whether this can be rectified by way of recombination. | |

| Synthetic epigenetics is an upcoming field of biology that involves modifying existing epigenetic pathways by constructing artificial and specific pathways. Synthetic epigenetics, therefore, provides the tools for dissecting epigenetic signaling information and has the potential to explore so far unapproachable domains in both basic and clinical research. | |

| Researchers have surprised the medical world with a study concluding that smoking does not shorten telomeres. The study suggests that telomere length in adults should be regarded as a static biomarker that does not significantly change during adult life. | |
|
| Latest results from a project to discover what makes a cancer patient more likely to suffer adverse side-effects after radiotherapy have shown that a combination of biological markers and certain genetic changes can predict radiation sensitivity. | |
|
| Being able to analyze gene expression patterns is essential for understanding protein function, biological pathways and cellular responses to external and internal stimuli. This article aims to provide a brief overview of the processes that underpin gene expression and the techniques that can be used to quantify the expression of specific genes. | |
