A Hélice do DNA
Deoxyribonucleic acid, or DNA, is the genetic material responsible for passing traits from generation to generation in all organisms and most…
O Dogma Central
The central dogma of biology states that information encoded in the DNA is transferred to messenger RNA (mRNA), which then directs the synthesis of…
Células Procarióticas
Prokaryotes are small unicellular organisms in the domains Archaea and Bacteria. Bacteria include many common organisms such as Salmonella and…
Compartimentalização Eucariótica
One of the distinguishing features of eukaryotic cells is that they contain membrane-bound organelles—such as the nucleus and…
A Árvore da Vida - Bactérias, Arquea, Eucariontes
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the…
Mutações
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors.…
Evolução do Gene - Rápida ou Lenta?
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do…
Tamanho do Genoma e a Evolução de Novos Genes
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One…
Famílias de Genes
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or…
Tipos de Transferência Genética Entre Organismos
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and…
Combinado modificações genética e química capsídeo de vetores baseados em adenovírus transferência de genes para blindagem e orientação
Adenovirus vectors are potent tools for genetic vaccination and oncolytic virotherapy. However, they are prone to multiple undesired vector-host…
Gotícula única Digital cadeia da polimerase para detecção abrangente e simultânea de mutações nas regiões de Hotspot
Droplet digital polymerase chain reaction (ddPCR) is a highly sensitive quantitative polymerase chain reaction (PCR) method based on sample…
Navegando MARRVEL, uma ferramenta baseada na Web que integra genômica humana e modelo organismo genética informações
Through whole-exome/genome sequencing, human geneticists identify rare variants that segregate with disease phenotypes. To assess if a specific…
