The process of conversion of RNA (Ribonucleic acid) from the DNA (Deoxyribonucleic acid) template is known as Transcription. However, when the RNA (mRNA) template is converted into protein (amino acid sequence) it is known as translation. We can also say that transcription is the initial step of gene expression, which gives rise to the primary transcript in the form of mRNA with the help of enzyme RNA polymerase. While translation is the formation of the polypeptide chain, where the mRNA … [Read more...]
Difference Between A, B and Z DNA Double Helix Structure
The A and B forms of DNA are right-handed double helical structure, while Z form of DNA is left-handed double helical structure. The DNA molecule exists in different forms under the different condition in a cell, these variations in the conformations can be due to the salt concentrations, hydration level, DNA sequence, the presence of metal ions, direction of supercoiling, etc., in the cell. We all know the deoxyribonucleic acid (DNA) structure, is known to carry the genetic information and … [Read more...]
Difference Between Adaptation and Evolution
An example of the adaptation are some plants which have adapted their life in the deserts or the Grey whales who migrate thousands of miles every year from the cold Arctic Ocean to the coast of Mexico. However, an example of evolution is Darwin's Finches, which are the finches on the Galapagos Islands, where all have developed different beaks, originally these finched used to had a large beak for cracking nuts. So, adaptation contradicts evolution in the sense that adaptation is the … [Read more...]
Difference Between Living and Non-Living Things
The things which have life are living things, while the things which do not have life are non-living things. But if we try to find out the matter in deep, we will notice many important aspects on which we can differentiate living and non-living things. The most important point is that living things can reproduce and can give birth to the young of their kind, which non-living things cannot do. This is the era of machines and electronics, most of the things we use are non-living. We can observe … [Read more...]
Difference Between Endocrine and Exocrine Glands
Glands are the ingrowth of the top layer of the skin i.e. epithelium. This ingrowth can have a tubular, simple, branched or compound formation. They are the group of cells that release a chemical substance as per the demand of the body. We can divide them into two categories- Endocrine and Exocrine. These two play a critical role in controlling the body, its growth and development and other functions. The nature of the secretion is one of the critical points to distinguishing both glands. … [Read more...]
Difference Between Chromosomes and Chromatid
The chromosome is the most condensed form of DNA, which remains packed into a thread-like structure. On the other hand, a chromatid is the one-half copy of the newly formed chromosome, joined by the centromere to the original chromosome. Secondly, the chromosomes are present every time in the nucleus of each cell and thus carry the genetic material. While chromatids form during the cellular division processes of mitosis and meiosis. We can define Genetics as the study of the genetics or … [Read more...]
Difference Between Polyp and Medusae
The phylum Cnidaria has about 13,000 different species. The cnidarians come into two basic forms - polyp and medusae. The polyps are sessile tubular-bodied organisms which remain attached to the solid anchor like rocks. The main characteristic of them is the single, circular and terminal mouth that faces upwards to the water. They are primitive organisms that lack sense organs, velum and manubrium. The tentacles of polyps are located around the mouth region, forming a ring of tentacles in the … [Read more...]
Difference Between Surface Water and Groundwater
A major difference between surface water and groundwater is the location where they are found. On one side, you may find the surface water on the external parts of the earth’s crust, i.e. on the surface level. Rivers, streams, lakes, ponds etc., are the most common examples of sources of surface water. In contrast, the groundwater is present in the interior parts of the earth’s crust, i.e. underground level. Wells, tube wells, borewells, and springs are common sources of groundwater. The … [Read more...]
Difference Between SNP and Mutation
SNP (Single nucleotide polymorphism) and mutation are both related to the structural changes in the genome. While researching, people often use these two terms interchangeably. However, scientifically, one must be very careful while using them. All the individuals except for the twins have their own version of genome sequences. These variations are mainly due to the SNPs. The chances of occurrence of SNP are approximated as one per thousand base pairs. SNP indicates the condition where one … [Read more...]
Difference Between Gas and Liquid Chromatography
Both gas and liquid chromatography serve the same purpose, i.e., separating the components of any mixture. But they vary greatly if we talk about their working mechanisms, components used and the required conditions. Gas chromatography uses gas as its mobile phase for moving the particles of the sample inside the column. In contrast, in liquid chromatography, the mobile phase used to move sample particles is liquid in nature. The principle behind gas chromatography is that it uses, … [Read more...]
