Replication of DNA

One of the most important function of DNA is the replication of the another DNA. We all know that the DNA is the key factor for the transfer of the hereditary characters. But it is not an easy task for the cell to replicate the DNA it is the long and complex process. Lets discuss the methods that takes for the replication of DNA. Mostly it takes by the following three ways. 1. Dispersive method is one form for the replication of DNA. During this method the DNA replicate to make daughter DNA. The daughter DNA consists of a parental strand and a...

Science behind lightning

We all are familiar with lightning a flash of light which we observe at night during rainy or some stormy cloudy day. So you might have question on what causes the lightning. Well lighting are caused due to the collision of the negative and positive charge. The stormy cloud contains the water molecules and from here due to the movement of storm the positive and negative charge is formed and the negative charge moves from the top to the bottom part of the cloud being heavier and the light positive charge move to the upper part. In this way first...

Determine the strength of solution

The strength of the solution can be measured by two ways as comparison method and Strength determination method. The comparison method is classified as the dilute solution and concentrated solution. But this method is not suitable for the determination of the solution. The measurement of the solution can be determined by the strength of the solution methods. It is the real method for the determination of the solution as it involves different sub method for the determination they are 1. Percentage solution: It is categorized in the three ways....

Superposition and progressive and stationary waves

We all know how the energy is transferred in the wave. Yes it is due to the disturbance in the particles from its equilibrium position. So today lets discuss a new and interesting topic. Superposition theorem states that "If the large  waves are passing from a medium then the displacement of the resultant of the particle of the medium is given by the sum of vectorial of all the displacement of the particles through it by the waves." This theorem is very important and is used in the circuit analysis during which different amount of the charge...

Possibility of extinction of men in future

Well guys how are you. Today i have come here with a new topic. So is really the men are going to extinct from the world? Well the research done by the Canberra university and other university has put different theories regarding to this. Also Australian researcher Jenny graves has claimed that after 5 millions of years the male will be disappear from the whole earth. Actually the main reason behind this is that men possess a unique Y chromosome which determines the genetic as well as other other characteristic of male is degrading and will become...

Pre mendelian theory of inheritance

Inheritance is the process of transfer of hereditary character from parents to the offsprings. This is due to the inheritance that the two parents and their offsprings are more or less similar. We can easily distinguish the offsprings by observing with the parents face. It was Gregor Mendel who brought the concept of inheritance. Before him were also different philosopher as well as scholars gave their own opinion and gave their theory. All these theory are collectively known as pre mendelian view or theory. The pre mendelian views are as follows. 1....

Types of waves and its properties

Well so today lets discuss about the wave. Well what does it suggest? To know about the wave we first should know about the disturbance as the wave is related to it. The any change in the position of the body from the equilibrium is known as disturbance. The wave is applicable in all the field and is one of the pillar of the physics. The wave is defined as the form of the disturbance in which both the momentum as well as the energy is transferred simultaneously from the body when the body is in the periodic motion. The characteristics of the wave...

Working principle of discharge tube

The discharge tube helps to produce the cathode ray which can only be done by minimizing the pressure and maximizing the potential difference. First of all the discharge tube of 25-50cm is taken and having the diameter 3-5 cm is taken. They are made in such a way having the pressure pump to taken out. The one end is make cathode and other end is made anode. The positive terminal is made anode and the negative end is made cathode. So under various pressure it works differently so they are as follows.        When the...

A brief concept on diffusion and osmosis

The process of transfer of ions, molecules, particles from their higher concentration area to the lower concentration area. The factors that affect the rate of diffusion are 1. Temperature: The rate of diffusion is directly proportional to the temperature. When the temperature is raise then the rate of diffusion also raises, but when the temperature is deceases the rate of diffusion is also decreases. Hence it is one of the important factors. 2. Density: Density is another important factor responsible for the rate of diffusion. When the density...

History of diseases and its causes

It was Robert Koch,  a physician who first came to know about the disease that was attacking a particular herd of cattle and was destroying them. The farmer first told it to him and he began to search for it. He established a small laboratory in his room and began to investigate. During investigation he found a spiral shaped bacilli. He then wanted to know what kind of disease was it so he injected the disease causing bacteria to a healthy mouse up to many generations. During his search he found that the bacillus were reproducing by forming...

How does petrol engine works?

The petrol engine was made by Otto in 1876. It consists of the two valves inlet and outlet valves. As it was manufactured  by Otto it is also known as Otto engine. It performs the work by following four steps they are 1. Charging stroke:During this phase the inlet valve is opened due to which the vapors of petrol and air is sucked by pulling the piston downward. This is the first phase for the working of the petrol engine. 2. Compression stroke: This is the second phase for the working of the petrol engine. During this condition the piston...
