Homozygous Definition Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. In homozygous chromosomes, both alleles are either dominant or recessive. The dominant trait is represented by two capital letters … Read more
Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects which cannot be seen clearly through an unaided eye. However, each of these microscopes has distinct features and is suitable for … Read more
Plants and animals are made up of millions of cells and these cells have several similarities and differences. Considering that they are both eukaryotic cells, which means they have a true nucleus, that is enclosed and separated from other organelles … Read more
Heterochromatin Definition Heterochromatin is a tightly packed or condensed DNA that is characterized by intense stains when stained with nuclear stains, containing transcriptionally inactive sequences. It exists in multiple variations, up to four to five state, each of which is … Read more
Epithelial Tissue Definition Epithelial tissue is a type of animal tissue, consisting of closely aggregated polyhedral cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface. … Read more
Chromosome Definition A chromosome is a thread-like structure present in the nucleus or nuclear region of the cytoplasm that is made up of a single molecule of DNA (Deoxyribonucleic acid) and proteins, carrying some or all genetic materials of an … Read more
Taproot Definition Taproot is one of the two essential root systems where the primary root gives out branches of secondary and tertiary roots growing downwards as the primary root tapers towards the end. The Taproot system is the root system … Read more
Cold-blooded animals definition Cold-blooded animals are the animals that are not capable of regulating their body’s temperature according to the temperature of the surrounding. The body temperature of these animals fluctuates as they move in different surroundings with different temperatures. … Read more
Phenotype Definition Phenotype is a term used in genetics to refer to all the observable traits in organisms as a result of the interaction of the genotype with the environment. The term ‘pheno’ in ‘phenotype’ refers to ‘observe’ and thus … Read more
Natural selection definition Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition. Natural selection is one of the four primary mechanisms of evolution, along with … Read more
Image Source: Spencerbaron and YassineMrabet. Incomplete dominance definition Incomplete dominance is a mechanism of dominance in heterozygotes, where the dominant allele does not entirely overcome the phenotypic expression of the recessive allele, and there occurs an intermediate phenotype in the … Read more
Exocrine Glands Definition Exocrine glands are the glands with ducts that allow the cells to secrete their products into those ducts so that they can be released onto the surface of the target cells or organs. The cells of the … Read more
Differences between Primary and Secondary Immune Response In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen. A secondary immune response is elicited … Read more
Introduction This century alone, the world has faced localized and disseminated epidemics and pandemics, that have redefined science and the aspects of prevention and control of very infectious and contagious diseases. These characteristic diseases have a high infectivity rate and … Read more
Active and Passive Transport Definition Active and passive transport are the two main biological process which plays an important role in supplying nutrients, water, oxygen, and other essential molecules to cells and also by removing waste products. Both active and … Read more
MHC Class I and Class II differences (mhc i vs mhc ii) The major differences are: S.N. Characteristics MHC-I molecule MHC -II molecule 1. Distribution Present on almost all nucleated cells including platelets. Have a restricted tissue distribution and are … Read more
Rough Endoplasmic Reticulum (RER) The rough endoplasmic reticulum is a type of endoplasmic reticulum consisting of flattened sacs, studded with protein-synthesizing particles termed ribosomes on the outer surface. The rough endoplasmic reticulum is a part of the endomembrane system that … Read more
Differences between antigen and antibody Antibodies are produced by the immune system in response to antigens (material perceived as foreign). The antibody response to a particular antigen is highly specific and often involves a physical association between the two molecules. … Read more
Quantitative and Qualitative Data Definition Qualitative data is data concerned with descriptions, which can be observed but cannot be computed. On the contrary, quantitative data is the one that focuses on numbers and mathematical calculations and can be calculated and computed. So, … Read more
Genomics and Proteomics Genomics and proteomics are closely-related fields. The main difference between genomics and proteomics is that genomics is the study of the entire set of genes in the genome of a cell whereas proteomics is the study of the entire set of proteins … Read more
Differences between DNA and RNA (DNA vs RNA) Some of the differences are: S.N. Character DNA RNA 1. Full form Deoxyribonucleic Acid Ribonucleic Acid 2. Location DNA is found in the nucleus, with a small amount of DNA … Read more
