Science > Physics > Projectile Motion > Analytical Treatment of Projectile Motion When a body is thrown making an acute angle with the horizontal, the body is said to perform the projectile motion. The path of the body performing projectile motion is called a trajectory. Example: A ball thrown by a fielder to the wicketkeeper, […]
There are a variety of criminal defense strategies that a lawyer may utilize when defending a client in a criminal case. Courts will determine legal insanity. In this article, we shall study one of the strategies called The M’Naghten Rules. Insanity is a mental defect or disease that makes it impossible for a person to know what […]
Science > Physics > Motion in a Straight Line > Newton’s Equations of Motion In this article, we shall study to solve problems based on Newton’s equations of motion. First Equation of Motion: Let u = initial velocity of a body, v = final velocity of the body t = time in which the change in velocity takes […]
Science > Physics > Motion in a Straight Line > Numerical Problems on Displacement, Average Speed, Velocity In this article, we shall study to solve problems to calculate displacement, Average Speed, and average Velocity. Example – 01: A train travels a distance of 100 m due east in 10 seconds. What is its speed and […]
Science > Physics > Motion in a Straight Line > Terminology of Motion Motion is an important part of our life. Our daily activities involve motion of different kinds. In this topic, we shall study the terminology of motion. Mechanics: The branch of physics which deals with the effects of forces on object is called […]
The process in which a DNA molecule produces exact copy or replica of itself is known as replication of DNA. In eukaryotes, replication of DNA takes place inside the nucleus. In DNA replication, the double helix (parent strand) unzips forming two separate strands called templates. These templates provide the base sequences used to synthesize new DNA (daughter) strands. […]
There are three types of non-genetic RNA. They are mRNA, rRNA, and tRNA. These RNAs are produced on the DNA template by the process called transcription. mRNA or Messenger RNA: The mRNA molecule is always simple and straight without any fold and is transcribed from one strand of DNA. It constitutes 3 to 5 % […]
In this article, we shall study the difference between DNA and RNA, and also the structure of RNA. Differences between RNA molecules and DNA molecule: RNA contains ribose sugar units while DNA contains deoxyribose sugar unit. RNA contains the base uracil while DNA contains thymine. RNA is single-stranded, except in some viruses while DNA is […]
In this article, we shall study the structure of DNA. Each cell in a particular living organism contains the exact same DNA. The size of the DNA polymer is directly related to the complexity of the organism; more complex organisms tend to have larger molecules of DNA, while less complex organisms have smaller DNA. For e.g. […]
Karl Landsteiner in 1900 discovered that blood in all persons is not alike and hence clumping or agglutination occurs on the mixing of blood of certain persons. Blood group is determined by the antigens present on the surface of RBC’s. An antigen is a molecule (in this case a carbohydrate) that acts as a signal, […]
