Amwoga Khalwale DNA Polymerase I (Pol I) DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. Discovered by Arthur Kornberg in 1956, it was the first known DNA polymerase (and the first known of any kind of polymerase). It was initially characterized in E. coli and is ubiquitous in prokaryotes. In E. coli and many other bacteria, the gene that encodes Pol I is known … Read more
What Are Nitrates? A nitrate is any member of either of two classes of compounds derived from nitric acid, HNO3– and a positive ion such as NH4+. Nitrates are common components of fertilizers and explosives. Examples of nitrates include: Potassium nitrate KNO3) Sodium nitrate (NaNO3) Ammonium nitrate ( NH4NO3) etc. What You Need To Know … Read more
They are widely domesticated in South America as meat animals and transportation animals. Both species are primarily found in Peru, Ecuador, Chile, Argentina and Bolivia. The llama and Alpacas are members of the camel family, closely related to alpaca, guanaco and vicuna, which are known collectively as lamoids. Unlike camels, lamoids do not have the … Read more
Telescope A telescope is an optical instrument using lenses, curved mirrors or a combination of both to observe distant objects or various devices used to observe distant objects by their emission, absorption or reflection of electromagnetic radiation. A telescope objective is designed to capture light from something far away, so the light arriving is nearly … Read more
What Are P And NP Problem? Computer algorithms take a certain amount of time to solve the problem they are tasked with. Generally, you can roughly estimate how much time an algorithm will take using the number of elements they need to handle. Computer scientists call the number of elements N. Because some algorithms are more … Read more
Atomic Orbitals An atomic orbital is a mathematical function describing the location and wave-like behavior of an electron in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom’s nucleus. The term atomic orbital can also to the physical region … Read more
What Is A Two Dimensional (2D) Shape? A two-dimensional shape can be described as a flat plane figure or a shape that has length and width but no depth. Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces. Examples of two-dimensional shapes: Circle Square Triangle Rhombus Rectangle … Read more
Continue Statement The continue statement is used for the termination of the current iteration and not the whole loop. The continue statement can include an option optional label that allows the program to jump to the next iteration of a labeled loop statement instead of the current loop. In case, the continue statement needs to … Read more
Hyperbola A hyperbola is a conic section formed by intersecting a right circular cone with a plane at an angle such that both halves of the cone are intersected. This intersection produces two separate unbounded curves that are mirror images of each other. In other words, a hyperbola is a conic section formed by the … Read more
Specular/Regular Reflection In regular reflection, all the light that falls on the reflecting surface is reflected in a definite direction. It is produced on smooth surfaces like mirror, highly polished surfaces. Regular reflection can appear much brighter than diffuse reflections when seen from a large distance, because the reflected light is concentrated in a definite … Read more
