What is the advantage of adding SDS to gel electrophoresis? How can the results of gel electrophoresis be interpreted? Why are there multiple bands in gel electrophoresis? What factors affect gel electrophoresis? What is the purpose o...
How is gel electrophoresis used in paternity testing? Interpret this gel electrophoresis analysis. How can the results of gel electrophoresis be interpreted? What is the comb in gel electrophoresis? What is a DNA marker in gel electrophoresis?
We started ethidium DNA agarose gel electrophoresis when our ultracentrifuge broke down and we needed an alternative method to check the quality of our mitochondrial DNA preparations. Agarose proved convenient for sizing DNA; ethidium in gel and buffer allowed visualization of DNA bands immediately ...

Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for...
Historically, pulsed-field gel electrophoresis (PFGE) has been the primary way of DNA fingerprinting STEC to identify and investigate outbreaks. In the wake of the 1992-93 Jack in the Box outbreak, in 1996, the Centers for Disease Control and Prevention (CDC) founded PulseNet, a national labo...
data). Look at the data again and re-read the materials and methods section and the results section. Were the methods appropriate? Did they offer evidence to support the hypothesis? Was the data interpreted correctly? For example, was the gel band seen in lane 1 really brighter than the co...
“A popular target is histones, the positively charged small proteins that package DNA from chromosomes to form particles small enough to fit into cell nuclei. The site(s) and extent of methylation and acetylation determine whether or not particular genes are expressed.” In contrast, it is ...
How is DNA used in forensic entomology? How are base sequences coded in mRNA? How does Sanger sequencing work? Include all the required components and what they do to for sequence of the template strand results? What is the sequence of the template strand being sequenced within the blue box...
How do humans detect color? Considering your answer to this question, predict why some "colorblind" individuals are unable to distinguish between certain colors. 1. What purpose does the loading dye serve? 2. What is the purpose of the molecular weight ruler? 3. Analyze whether the DNA extrac...
