Genetics is the scientific study of heredity, gene structure, and function. This category delves into the fundamental principles of genetics, including topics such as DNA, genetic variation, and the regulation of gene expression. From exploring the genetic basis of human traits and diseases to understanding the role of genetics in evolution, learn about the science of heredity and its impact on our lives.
Genomic imprinting refers to an epigenetic phenomenon in which the expression of a gene depends on the parent it's inherited from. Some genes are expressed in a parent-specific manner, meaning they're active only when inherited from the mother or the father.
Genomics, a subfield of genetics, involves the study of the complete set of DNA within a single cell of an organism. The human genome, specifically, contains all of the biological information needed to build and maintain a human being.
The Rh factor derives its name from the Rhesus monkey, in which Landsteiner and Wiener first observed the antigen. However, the Rh factor is present in humans and is independent of the Rhesus monkey's blood group system.
Twins are individuals who are born from the same pregnancy and share the same birth date. They are characterized by a close genetic relationship, as they typically originate from the fertilization of a single egg by a single sperm, which then splits into two embryos.
A Genetic disorder is like a typo in the instructions that tell your body how to grow, develop, and work. You know how a recipe has steps to tell you how to make a cake? Well, our bodies have something like that too. It's called our DNA.
Genetic engineering, also known as genetic modification or manipulation, refers to the deliberate modification of an organism's genetic material using biotechnological techniques. It is a relatively young field, having first come into prominence in the latter half of the 20th century.
Gene therapy is a medical field that has shown potential for treating and potentially eradicating genetic disorders and other diseases by altering the genetic makeup of an individual's cells.
Genetic screening is a process used to identify variations or alterations in an individual's genetic material (DNA) to assess their risk of developing certain genetic disorders or conditions.
The journey of DNA sequencing began in earnest in the mid-20th century. With the unveiling of the DNA structure by James Watson and Francis Crick in 1953, scientists recognized that within these double helices lay the code of life
The polymerase chain reaction (PCR) is a revolutionary molecular biology technique that allows for the amplification of specific segments of DNA in vitro.
