Resistance To HIV Drug Growing, Study Finds
HIV resistance to the antiretroviral drug tenofovir (Viread) is increasingly common, a new study finds. The researchers said their finding is surprising and alarming because the drug plays a major rol...
Grabbing A Parasite By The Tail: U-M Team Solves "Jumping Gene" Mystery
Deep within your DNA, a tiny parasite lurks, waiting to pounce from its perch and land in the middle of an unsuspecting healthy gene. If it succeeds, it can make you sick. Like a jungle cat, this para...
Video: Man Claims He Caught Three-Eyed Fish In Gowanus Canal
If the man in the video is to be believed, the first Gowanus Canal monster is your regular run-of-the-mill three-eyed fish. It was always only a matter of time until the putrid toxic waters of the Gow...
Rare Mutation May Extend Survival In Lung Cancer Patients With Brain Metastases
Most patients with non-small cell lung cancer (NSCLC) that has metastasized to the brain have a dire prognosis. But Yale researchers have identified a subset of those patients with a rare genetic muta...
Mutant Plant Munches TNT, Could Help Solve Cleanup Problems
A new study suggests that a mutant variety of a cabbage relative thrives on TNT, pointing the way to a potentially elegant solution for millions of acres of contaminated land. The plant, Arabidopsis t...
How Chronic Inflammation Can Lead To Cancer
Researchers discover how the immune system can create cancerous DNA mutations when fighting off infection. Chronic inflammation caused by disease or exposure to dangerous chemicals has long been linke...
“Freezing A Bullet” To Find Clues To Ribosome Assembly Process
Ribosomes are vital to the function of all living cells. Using the genetic information from RNA, these large molecular complexes build proteins by linking amino acids together in a specific order. Sci...
Removal Of Ovaries Associated With Decrease In Breast Cancer Death In Women With Cancer, BRCA1 Mutation
Women who carry a germline mutation in either the BRCA1 or BRCA2 gene face a lifetime risk of breast cancer of up to 70 percent. Once they are diagnosed with breast cancer, they face high risks of bot...
Mutation - DNA MUTATION

DNA codon table
The genetic code is traditionally represented as a RNA codon table due to the biochemical nature of the protein translation process. However, with the rise of computational biology and genomics, prote...
Expanded genetic code
An expanded genetic code is an artificially modified genetic code in which one or more specific codons have been re-allocated to encode an amino acid that is not among the 20 encoded proteinogenic ami...

Noncoding DNA
In genomics and related disciplines, noncoding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some noncoding DNA is transcribed into functional non-coding RNA ...
Mutation
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from damage to DNA whic...

Messenger RNA
Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression....
Pyrimidine dimers
Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions. Ultraviolet light induces the formation of covalent linkages by reactions localized on...

Fusion transcript
Fusion transcript is a chimeric RNA encoded by a fusion gene or by two different genes by subsequent trans-splicing. Certain fusion transcripts are commonly produced by cancer cells, and detection of ...
Fluorophore
A fluorophore (or fluorochrome, similarly to a chromophore) is a fluorescent chemical compound that can re-emit light upon light excitation. Fluorophores typically contain several combined aromatic g...

PCR mutagenesis
Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional changes to the DNA sequence of a gene and any gene products. Also called site-specific mutagenesis...
Transition (genetics)
In genetics, a transition is a point mutation that changes a purine nucleotide to another purine (A ↔ G) or a pyrimidine nucleotide to another pyrimidine (C ↔ T). Approximately two out of three single...

BRCA mutation
A BRCA mutation is a mutation in either of the genes BRCA1 and BRCA2. Harmful mutations in these tumor suppressor genes produce a hereditary breast-ovarian cancer syndrome in affected families. Mutat...
Suppressor mutation
A suppressor mutation is a second mutation that alleviates or reverts the phenotypic effects of an already existing mutation. Genetic suppression therefore restores the phenotype seen prior to the or...
