In each type of cell, like a muscle cell or a skin cell, different genes are expressed (turned on) or silenced (turned off). If the cells that are turned on mutate, they could—depending on what role ...

Students model how scientists use DNA microarrays to determine levels of gene expression in breast cancer patients, and then choose treatments based on what they learn. Normal-functioning DNA codes ...

Launched in 1990, The Human Genome Project was a monumental effort to sequence and analyze the entire human genome to understand how genetics influence health. While the Human Genome Project helped ...

Two of the critical issues that arise when examining DNA microarray data are (1) determination of which genes best discriminate among the different types of tissue, and (2) characterization of ...

The field of DNA microarray data analysis is getting increasingly complicated as scientists develop new array technologies and analysis algorithms, yet accurate introductory information on the subject ...

The F9 teratocarcinoma cell line is a well-documented model system in primary cell lineage differentiation. After exposure to trans-retinoic acid, these cells can develop into two distinct forms of ...

In a recent study posted to the Research Square* preprint server, researchers differentiated between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants using nanotechnology. Study: ...
