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 in sex chromosomes, … Read more List of disorders due to chromosomal aberration

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 isolates and purifies. … Read more Vectors- characteristics, classification, features, types

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 tests vary. Diagnostic … Read more Differences between Real-Time PCR and Rapid Diagnostic Test

Vectors for gene cloning: Plasmids and Bacteriophage

Vectors for gene cloning- Plasmids and Bacteriophage

Vectors for gene cloning: Plasmids and Bacteriophage Image Sources: Wikipedia and Vector Stock In molecular biology, a vector refers to a DNA molecule that transfers genetic material into another cell and the genetic material gets to incorporate in the cell genome and expressed. The foreign DNA carried by the vector is called recombinant DNA. The … Read more Vectors for gene cloning: Plasmids and Bacteriophage

Polymerase Chain Reaction (PCR)

Polymerase Chain Reaction (PCR)

Polymerase Chain Reaction (PCR) It is one of the most important biotechnological tools developed. It refers to a biological technique that helps to produce several copies of DNA outside of any living cell. DNA polymerase is the key enzyme that is present behind the whole process. The enzyme involved in the synthesis of new DNA … Read more Polymerase Chain Reaction (PCR)

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 has several pros … Read more Loop-mediated Isothermal Amplification (LAMP)

Chemical Factor of Mutation

Chemical Factor of Mutation

Chemical Factor of Mutation What is a mutation? Any changes in the DNA gene sequence in such a way as to alter the genetic message carried by that gene sequence. What is mutagen? Any biological, physical or chemical agent that changes the genetic material, usually DNA of an organism is called mutagen. What is mutagenesis? … Read more Chemical Factor of Mutation

Cell Transformation (normal cells to cancerous cells)

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 changes in evening … Read more Cell Transformation (normal cells to cancerous cells)
