P1 is a temperate bacteriophage that infects Escherichia coli and some other bacteria. When undergoing a lysogenic cycle the phage genome exists as a plasmid in the bacterium [1] unlike other phages (e.g. the lambda phage) that integrate into the host DNA. P1 has an icosahedral head containing the DNA attached to a contractile tail with six ...
The research course is only offered for the first half of the school year; by the second half of the year, students focus on various specialized science courses (life science, physical science, and advanced biology). For Grade 10, however, research is integrated into the advanced chemistry course.
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans.This could include a sample of a microorganism, virus or toxin that can adversely affect human health.
In Nepal 12-year school is categorised in two stages: Primary school (Grade 1 to Grade 8) and Higher Secondary school (Grade 9 to Grade 12). For college it averages four years for a bachelor's degree (except BVSc and AH which are five year programmes and MBBS which is a five and half year programme) and two years master's degree.

A grade 8 is also equivalent to an A*, however the grade 9 is the top end of the A*. The former C grade is set at grade 4 (known as a 'standard pass') and grade 5 (considered a 'strong pass') under the numerical scheme. Although fewer qualifications have tiered examinations than before, the tiering system still exists.
The Scottish equivalent was the O-grade (replaced by the Standard Grade). The AO-Level (Alternative Ordinary Level) was formerly available in most subject areas. Sometimes incorrectly known as the Advanced Ordinary Level, the AO-Level syllabus and examination both assumed a higher degree of maturity on the part of candidates, and employed ...
Scavenging unites animals which normally would not come into contact, [12] and results in the formation of highly structured and complex communities which engage in nonrandom interactions. [13] Scavenging communities function in the redistribution of energy obtained from carcasses and reducing diseases associated with decomposition.
Ribonuclease P (EC 3.1.26.5, RNase P) is a type of ribonuclease which cleaves RNA.RNase P is unique from other RNases in that it is a ribozyme – a ribonucleic acid that acts as a catalyst in the same way that a protein-based enzyme would.
