Protein phosphatase 2 (PP2), also known as PP2A, is an enzyme that in humans is encoded by the PPP2CA gene. [ 2 ] [ 3 ] The PP2A heterotrimeric protein phosphatase is ubiquitously expressed, accounting for a large fraction of phosphatase activity in eukaryotic cells. [ 4 ]
The Kenya Certificate of Secondary Education (KCSE) is an academic certificate awarded to candidates upon completion of secondary education in Kenya. [ 1 ] The first KCSE exam was held in 1989 at the same time as the last Kenya Advanced Certificate of Education (KACE), which it replaced as the entrance requirement for Kenyan universities.
MrBayes is also able to infer ancestral states accommodating uncertainty to the phylogenetic tree and model parameters. MrBayes 3 [32] was a completely reorganized and restructured version of the original MrBayes. The main novelty was the ability of the software to accommodate heterogeneity of data sets.
An alpha-helix with hydrogen bonds (yellow dots) The α-helix is the most abundant type of secondary structure in proteins. The α-helix has 3.6 amino acids per turn with an H-bond formed between every fourth residue; the average length is 10 amino acids (3 turns) or 10 Å but varies from 5 to 40 (1.5 to 11 turns).
Since 1985, public education in Kenya has been based on an 8-4-4 system, [2] [3] with eight years of primary education followed by four years of secondary school and four years of college or university. Prior to the 8-4-4 model, Kenya's education system was structured as 7-4-2-3 curriculum.
In addition, machine learning has been applied to systems biology problems such as identifying transcription factor binding sites using Markov chain optimization. [2] Genetic algorithms, machine learning techniques which are based on the natural process of evolution, have been used to model genetic networks and regulatory structures. [2]
The first clinical prediction model reporting guidelines were published in 2015 (Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD)), and have since been updated. [18] Predictive modelling has been used to estimate surgery duration.
