Indication of the origin and terminus of DNA replication on a GC skew and cumulative GC skew plot. Richness of G over T in the leading strand, resulting in a GC skew sign at the origin and terminus. GC skew is when the nucleotides guanine and cytosine are over- or under-abundant in a particular region of DNA or RNA. GC skew is also a ...
TurboMass is GC/MS software created by PerkinElmer. Universal Mass Calculator Freeware: UMC is programmed as a mass spectrometry tool to assist interpreting measurement results, mainly derived from molecular or quasi-molecular ions. It can be used for the calculation of: Mass deviation (mmu or ppm) of measured mass from given empirical formula
Melting curve analysis is an assessment of the dissociation characteristics of double-stranded DNA during heating. As the temperature is raised, the double strand begins to dissociate leading to a rise in the absorbance intensity, hyperchromicity.
Given the frequency of GC two-nucleotide sequences, the number of CpG dinucleotides is much lower than would be expected. [14] A 2002 study revised the rules of CpG island prediction to exclude other GC-rich genomic sequences such as Alu repeats. Based on an extensive search on the complete sequences of human chromosomes 21 and 22, DNA regions ...
MDCalc was founded by two emergency physicians, Graham Walker, MD, and Joseph Habboushe, MD, MBA, [5] and provides over 500 medical calculators and other clinical decision-support tools. [6] The MDCalc.com website was launched in 2005. [5] In 2016, MDCalc launched an iOS app, [7] followed by an Android app in 2017. [8]
An AI death calculator can now tell you when you’ll die — and it’s eerily accurate. The tool, called Life2vec, can predict life expectancy based on its study of data from 6 million Danish ...
GC–MS is used for the analysis of unknown organic compound mixtures. One critical use of this technology is the use of GC–MS to determine the composition of bio-oils processed from raw biomass. [29] GC–MS is also utilized in the identification of continuous phase component in a smart material, magnetorheological (MR) fluid. [30]
This prediction was rejected by many studies that used the complete human genome data. [1] [7] [8] [9] The genome organization of cold-blooded vertebrates is characterized by low GC content levels and lower compositional heterogeneity. [10] [11] [12] This prediction was disproved by finding high and low GC content domains in fish genomes. [13]
