摘要: Although some of the initial controversy surrounding DNA profiling has been resolved, courts have been misled about the strength of DNA evidence.关键词: How convincing is DNA evidence?, Artículo DOI: 10.1038/368285a0 被引量: 48
Small errors occasionally occur during DNA copying, and others are sometimes introduced by environmental mutagens. These small errors are the fodder fornatural selection: Some of these errors result in sequences that produce fitter organisms, though most have little effect; however, many can prove le...
DNA is the genetic material found within the cell nuclei of all living things. In mammals the strands of DNA are grouped into structures called chromosomes. With the exception of identical siblings (as in identical twins), the complete DNA of each individual is unique. ...
In other words, the cells could not recover from the collision between DNA polymerase and the transcription bubble. As it turns out, scientists have found very little evidence that this type of encounter occurs in nature, which is probably the result of the deleterious, and likely lethal, ...
The 9-1-1 DNA checkpoint clamp is loaded onto 5′-recessed DNA to activate the DNA damage checkpoint that arrests the cell cycle. The 9-1-1 clamp is a heterotrimeric ring that is loaded in Saccharomyces cerevisiae by Rad24-RFC (hRAD17-RFC), an alternate clamp loader in which Rad24 rep...
DNA Mutation, Variation and Sequencing Chromosome abnormalities can be inherited from a parent (such as a translocation) or be "de novo" (new to the individual). This is why, when a child is found to have an abnormality, chromosome studies are often performed on the parents. National Human...
How is DNA replicated? What is the name of the technique used to determine if DNA comes from a particular individual? What protein unwinds and separates DNA strands in DNA replication? What is DNA? What is the evidence of DNA as genetic material?
Around the same time, researchers James Watson and Francis Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used Franklin's images, along with their own evidence for the double-stranded nature of DNA, to argue that DNA actual...
