Blood is the type of connective tissue found in our body and plays a significant role in transporting various substances to different parts of the body. Lymph is the white colour fluid tissue, made up of white blood cells and lymphocytes and plays a significant role in carrying the white blood cells to and from the bones and lymph nodes. Secondly, Blood plays a leading role in carrying oxygen and carbon dioxide. At the same time, Lymph is a part of the body's immune system works in defence … [Read more...]
Difference Between Molecules and Compounds
When the chemical bonds unite any atoms (two or more) is known as a molecule. But such type of molecules that consist of different atoms (two or more) of different chemical elements are known as compounds. However, it is a fact that all compounds are molecules, but all molecules are not compounds. So, we can say that any combination of atoms is a molecule, but when the combination of atoms is from different elements, it is known as the compound. Let's take an example to understand in a better … [Read more...]
Difference Between mRNA, tRNA and rRNA
mRNA has a linear structure having uracil base instead of thymine, and its secondary structure could be hairpin, stem-loop, etc. ; while tRNA has Cloverleaf structure that carries three specific stem-loops; and rRNA has much complex structure with numerous folds and loops. mRNA acts as the messenger of DNA; tRNA carries amino acids during protein synthesis; rRNA is the protein producer of the cell. These three RNA plays a vital role in the process of transcription and further in protein … [Read more...]
Difference Between Apoptosis and Necrosis
The natural process which leads to the cell death is called as apoptosis, but when the cell death happens due to attack certain external factors like bacteria, virus or fungus, or any toxicity, injury, leads to necrosis. Apoptosis is the self-controlled event that occurs under favourable physiological conditions and the cell itself actively participate in the process. During necrosis, the cell is unable to maintain the homeostasis, which leads to the inflow of water and extracellular ions in … [Read more...]
Difference Between Breathing and Respiration
Breathing is the biophysical process which involves the inhaling and exhaling of air through lungs, whereas respiration is the biochemical process which involves in generating the energy by breaking down the glucose which is further used by cells in various function. Breathing is distinct from respiration in many ways, though both are essential for living organisms. As discussed above the mechanism of breathing is associated with the respiratory organs like the nose, lungs, etc., while … [Read more...]
Difference Between Point and Frameshift Mutations
The changes in the single base or nucleotide in the nucleotide sequence and thus changing its complementary base also it is called as point mutations, while when there are insertions or deletions of more than one base pair in the nucleotide sequence it is known as frameshift mutations. Mutations can be defined as any kind of change in the nucleotide sequence or genetic code, which altering the gene structure as well as the amino acids and the proteins too. These mutations occur in the DNA … [Read more...]
Difference Between Mutation and Variation
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 another, 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 body growth and development. These cells … [Read more...]
