Disorder due to chromosomal aberration

Image Source: Botany Studies. Chromosomal aberration definition Chromosomal aberration is a condition in which deletion or duplication of a particular chromosome in a set, lead to monosomy, nullisomy, trisomy, tetrasomy. Some disorders in human being due to chromosomal aberrations are as follows: Klinefelter syndrome (XXY) It is due to a trisomic condition …

Vectors- characteristics, classification, features, types

Vectors

Vectors are DNA molecules that are used as a vehicle to carry foreign DNA fragments into other cells where they can replicate and/or express. Among these most commonly used vector is a plasmid. Characteristics of vectors: Self replicating, multiple copies. Replication origin site. Cloning site. Selectable marker gene. Low molecular weight. Easily …

Differences between Real-Time PCR and Rapid Diagnostic Test

Differences between Real-Time PCR and Rapid Diagnostic Test

Rapid Diagnostic Test vs Real-Time PCR (qPCR) There are several diagnostic tests that have been authorized for Emergency Use by the FDA for diagnosis of a wide range of infections. Notably, these diagnostic tests aim at identifying an infected individual from a non-infected person, using different working principles and duration for the …

Loop-mediated Isothermal Amplification (LAMP)

Loop-mediated Isothermal Amplification (LAMP)

Introduction ABBREVIATION: Loop-mediated Isothermal AMPlification. Diseases are the primary constrains for the development of any living forms i.e., both plants and animals including humans. Diagnosis is a critical step for effective treatment and control of infectious diseases. PCR (Polymerase Chain Reaction) has revolutionized the earlier detection of infection, tumor, etc., However, LAMP …

RNA Interference (RNAi)

RNA Interference (RNAi)

RNA interference is a natural phenomenon by which an mRNA is silenced thereby inhibiting the protein coded from that particular mRNA. Scientists have been working on this field from 1990 and finally, two scientists named Andrew Fire and Creg C. Mello shared the Nobel Prize in Physiology or Medicine for their work …

Cell Transformation (normal cells to cancerous cells)

Cell Transformation (normal cells to cancerous cells) Cell transformation is a process in which the addition of certain malignant characteristics in the cell due to alteration in genetic material. induced by chemicals, carcinogens, radiations, viruses. History In 1901 Hugo de Vries first used the term mutation to describe the sudden heritable phenotypic …
