The Cre- loxP System: A Powerful Tool in the Genetic Toolbox
Dec 4, 2023 · Sternberg pondered about the underlying mechanism; he suspected that there must be a genetic hotspot for recombination located at the terminal ends of the linear genome to facilitate plasmid cyclization. 1 . The genesis of Cre-loxP recombinationConsistent with his hypothesis, Sternberg’s experiments revealed a small fragment of P1 DNA at the end of the genetic map that was likely responsible ...

Insights into qPCR: Protocol, Detection Methods, and Analysis
Nov 8, 2023 · qPCR, also known as real-time PCR, is an extension of traditional PCR, where DNA amplification over time is quantitated by measuring fluorescence from dyes intercalating into nascent DNA strands or by cleavage of target-specific probes. Therefore, the method combines detection with amplification, providing researchers with crucial data in real ...
Optimizing PCR: Proven Tips and Troubleshooting Tricks
Feb 23, 2024 · Template DNA. Template amount, source, and secondary structures or GC-rich regions may affect the reaction. 7. The amount of template depends on the DNA copy number. For a standard PCR reaction with 25-30 cycles, roughly 10 4 copies of the template DNA are sufficient to generate a detectable amount of PCR product. 7; The DNA required for a given reaction also depends on the source.

How Cloud Labs and Remote Research Shape Science
Mar 18, 2024 · Inception and Development of Remote Labs for Scientific Research. The idea of remote work can be traced back to the 1970s when Jack Nilles, a NASA engineer, proposed the use of telecommuting to alleviate traffic congestion. 4 The advent of personal computers and widespread internet access in the early 2000s has contributed to the concept of remote work being popularly accepted as a viable ...
An Introduction to Glycoproteins | The Scientist Magazine®
Jul 18, 2023 · N-glycosylation and O-glycosylation are the most common forms, 1 while phosphoglycosylation and S-glycosylation are extremely rare. Depending on the type, glycosylation occurs in different parts of the cell, primarily the endoplasmic reticulum (ER) and the Golgi apparatus. 10. The addition of carbohydrates to proteins via glycosylation affects how proteins fold, provides specific instructions ...
Hybrid Animals Are Not Nature’s Misfits - The Scientist Magazine®
May 1, 2021 · At some point in the past, black-tailed jackrabbits (Lepus californicus) and snowshoe hares (L. americanus) crossbred, with the hybrids mating again with snowshoe hares.A combination of whole-genome and whole-exome sequencing revealed that the resultant hares retained a variation of the Agouti gene that led to brown, rather than white, coat color in hare populations experiencing mild, less ...
