The changes in the nucleotide sequence at the DNA level or in any one of the base pairs is known as mutation, while the genetic variation is how one individual of a species variate from the other one, variation can be due to changes in the nucleotide sequence like insertions, deletions, any genetic rearrangements or any environmental factors. We all are aware of the DNA, RNA which are said as the genetic material and consist of the codes or bases A, C, G and T, and their combinations make the … [Read more...]
Difference Between Covalent, Metallic and Ionic Bonds
Covalent bond occurs between the two non-metals, metallic bond occurs between two metals and the ionic bond occurs between the metal and the non-metal. Covalent bond involves the sharing of electrons, while metallic bonds have strong attractions and ionic bonds involve the transferring and accepting of electrons from the valence shell. The adhering property of an atom, in order to arrange themselves in a most stable pattern by filling their outermost electrons orbit. This association of atoms … [Read more...]
Difference Between Cation and Anion
The ion that has the positive charge is called a cation, while the ion which has the negative charge on it is called as an anion. Secondly, the cation which is positively charged always gets attracted to the cathode (negative electrode), and the anion which is negatively charged get attract towards the anode (positive electrode). An atom or groups of atoms in which the number of protons and electrons are unequal, which gives them either the positive charge or negative charge such atoms are … [Read more...]
Difference Between Active and Passive Transport
Active transport uses energy (ATP) for the moving the molecules in and out of the cellular membranes and therefore remain active, while in passive transport the molecules do not use energy for their movements and so the name is given as passive. We all know that cell is the basic unit of life. It is responsible for all the activities that occur inside our body. But some specialized cells are assigned to do the specific task, which is essential for the body growth and development. These cells … [Read more...]
Difference Between Introns and Exons
Introns or the intervening sequence are considered as the non-coding part of the genes, while the exons or the expressed sequence are known to be as the coding part for proteins of the genes. Introns are the common attribute found in the genes of the multicellular eukaryotes like humans, while exons are found in both prokaryotes and eukaryotes. The traditional method for the flow of biological information in the living being is that the DNA makes RNA and then RNA makes proteins. These methods … [Read more...]
Difference Between Absorption and Adsorption
Absorption is the process which takes place, when one substance enters the volume or bulk of another substance, while adsorption is the condition which occurs on the surface of the substrate. In the case of adsorption, there are the intermolecular forces, which make the molecules to hold each other, but in absorption, there is soaking of the liquid or gas by the solid rather any forces applied on molecules. Here we noticed that there is the common term used in both the words is the … [Read more...]
Difference Between Cellulose, Starch and Glycogen
These three polysaccharides differ in their glycosidic linkages and their functions too. Starting from the cellulose which is the monomer of beta glucose and is found in plant cell wall only. While Starch and Glycogen act as the carbohydrate reserve in plants and animals respectively. Though their chains have slight differences at the branching point, which is described below. We all are aware of the importance of carbohydrate, whether it is plants, animals (including humans), or … [Read more...]
Difference Between Endothermic and Exothermic Reactions
Such chemical reaction in which the energy is absorbed in the form of heat is known as the endothermic reaction, while such chemical reactions in which energy is released or evolved in the form of heat is known as the exothermic reaction. So the main difference between these terms lies in the form of energy used or released during any chemical reaction. Chemical reactions not only takes place in laboratories, they happen in ones day to day routines, in our body also. For instance melting of … [Read more...]
Difference Between Red blood cells (RBC) and White blood cells (WBC)
RBC or Red blood cells play the vital role in carrying oxygen to the tissues of different parts of the body. Conversely WBC or White blood cells help in the defense mechanism of the body by creating antibodies. Secondly, RBC contains hemoglobin, which gives the red color to the blood and occupies around 45-50% of the total volume of the blood, while WBC is colorless, due to the absence of hemoglobin in them and comprises only 1% of the total volume of the blood. Red blood cells, White blood … [Read more...]
Difference Between Acid and Base
Such substances that donate their hydrogen ion (H+) (proton donor) and accepts the electron to another is called an acid. They have pH less than 7.0. But such substances that accept the proton and donate electron is called as the base. They have pH more than 7.0. Acids are sour, while bases are bitter. Acids and Bases are one of the most important parts of chemistry, but also play their significant role in another field of science. There are many definitions which differentiate the substances … [Read more...]
