Moreover, the phenotype of every tissue is defined by its own characteristic pattern of transcribed genes, which changes, when the cells are exposed to a signal, such as a dietary or a stress molecule. Tissue- and signal-specific gene expression is the central mechanism to control the general...
Gene expression is the process of how a gene works within a cell. Researchers commonly study gene expression to determine how...
Today, scientists no longer speak of the sequence hypothesis. Instead, the notion thatnucleotidesequences (genes) directly dictate amino acid sequences is known ascolinearity(Figure 1). Scientists have confirmed that colinearity is a regular occurrence among many viruses, like the ones Benzer studied...

What is autosomal gene expression?Autosomal Chromosomes and Genes:The most accurate way to tell if a mutation is autosomal is to identify the location of the abnormal gene. If it is on one of the 22 pairs of autosomal chromosomes, then it is an autosomal mutation. However, the likelihood ...
gene. When the virus infects the cell,the therapeutic gene gets incorporated into the cell chromosomes. The new gene causes a protein to be produced which is hoped to have some positive therapeutic effects, either providing an otherwise missing protein, or causing the destruction of harmful cells...
Gene therapy is designed to treat diseases by introducing exogenous DNA or RNA into human target cells, which may be achieved by a few different methods. It is used to treat inherited genetic disorders: to correct or compensate for the patient’s abnormal gene, or to silence or inhibit the ...
Gene arrays are solid supports upon which a collection of gene-specific nucleic acids have been placed at defined locations, either by spotting or direct synthesis. In array analysis, a nucleic acid-containing sample is labeled and then allowed to hybridize with the ...
Hepatitis C is a silent yet formidable liver infection caused by the hepatitis C virus (HCV). Unlike its acute form, which often resolves on its own, chronic hepatitis C persists, potentially leading to severe liver[more...] Epigenetic Changes in Immune Cells Linked to Alzheimer’s Disease ...
