Ethical problems in cloning animals and humans
By: Diana Birdwell
When it comes to cloning humans and animals, we are duplicating them in to what we want them to be. So if they clone the first off clone of person one, that is making an exact copy of that person. Cloning humans and animals defies...
How gene expression creates proteins
By: Alicia M Prater PhD
Proteins are the result of gene expression. They are often referred to as gene products because of the central dogma of biochemistry: DNA to RNA to protein. Genes are expressed when they are "on", meaning that their protein product is made and used in the...
The emerging role of epigenetics in disease
By: Alicia M Prater PhD
Over the past few decades, the role of genetics in disease has become a topic of many research studies. However, an already complicated field has become increasingly complex with the advent of epigenetics. This relatively new field focuses on chemical alterations of the genetic material...
The importance of DNA replication in the lab
By: Alicia M Prater PhD
DNA replication, often through the polymerase chain reaction (PCR) or bacterial culture, is extremely important in laboratories conducting research on a number of diseases.When isolated from the blood or cells of a living organism, the amount of any particular portion of DNA is extremely...
Introduction to skin genetics
By: Blade619
There are several genes known to be involved with skin pigmentation, these are: SLC24A5, MC1R, SLC45A2, ASIP, MATP, TYR, and OCA2. The most important of these genes in suspected order is SLC45A5 (solute carrier family 24, member 5), MC1R (melanocortin 1 receptor) and finally SLC45A2...
Siamese twins: Conjoined twins explained
By: Saphira Xenno
Firstly, the correct term for twins born in this nature is conjoined twins, not Siamese twins. The term comes from a pair of male conjoined twins named Chang and Eng Bunker born in 1811, who were perhaps the most famous conjoined twins of there time...
Understanding DNA structure
By: Alicia M Prater PhD
Deoxyribonucleic acid (DNA), less commonly referred to as deoxyribose nucleic acid, was discovered in the 1800s by a Swiss biochemist named Miescher. In 1953, James Watson, Francis Crick, and Rosalind Franklin used breakthrough imaging techniques, specifically X-ray crystallography, to determine that DNA is double-stranded and...
Gene expression explained
By: Alicia M Prater PhD
Gene expression is the process by which proteins are made. Proteins carry out almost all of the essential processes of life as they include enzymes, transcription factors, and the cellular machinery. Proteins are often referred to as gene products because of the central dogma of...
By: Darian Peters
Deoxyribonucleic acid, DNA, is the molecule of heredity that contains the genetic code for generating and maintaining an organism. To understand an organism, how it functions, how it develops, how it evolved, and what diseases may befall it, etc. it helps to know what the...

Rapidly advancing science of gene therapy seems to have made its foray into the hair loss industry. Scientists at the University of Pennsylvania have found that by manipulating a certain gene in Mice (Wnt) they were able to regenerate hair follicles. This particular gene manipulation...
