Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

From synthetic biology and gene therapy to data storage and biofuel production, the demand for synthetic DNA is rising. (1) Chemicals remove the 5’-hydroxyl protecting group. The nucleosides are rich ...

It coats the DNA and shuts down gene expression on that X. For genes to escape, researchers hypothesize, certain sequences on the X, so-called escape elements, attract proteins that help nearby genes ...

Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed.

By identifying which genes in the cancer cells are working abnormally, doctors can better diagnose and treat cancer. One way they do this is to use a DNA microarray to determine the expression ...

including sequencing technologies and DNA and RNA-based techniques utilizing anything from cultures and tissues, to single cells and environmental samples. Download this infographic to learn about ...

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...
