Problems and challenges of fighting genetic diseases
By: Rick Badman
Genetic diseases present some problems and challenges that have to be dealt with to possibly make health care less expensive and more effective. I believe it should start at birth with DNA referencing being carried out on newborns. A DNA sample would be taken and...
Book reviews: The 10,000 Year Explosion, by Gregory Cochroan and Henry Harpending
By: Art Young
The 150 year anniversary of Charles Darwin's seminal book on evolution, "The Origin of the Species," is an appropriate time for an important expansion on his ideas. This has come in the form of "The 10,000 Year Explosion" by Gregory Cochran and Henry...
Introduction to the human cell
By: Janette Peel
You cells are the smallest unit of your body and are responsible for the most fundamental processes in life, such as breathing, moving and reproducing.Every tissue in your body is made up of groups of cells with specialized functions, linked by intricate systems of...
How genetic mutation influences the process of evolution
By: Alicia M Prater PhD
Evolution is the process by which speciation (the creation of species) occurs. Each type of organism is a species, divided into these groupings by characteristics such as anatomy and physiology. Evolution also refers to the adaptations that occur in organisms, such as treatment resistance in...
Understanding the Human Genome Project
By: Janette Peel
Locked inside your body, amongst the tiny strands of DNA are the secrets of what makes you who you are; your body, your life and your personality. The human genome is the complete description of every one of the genes that you carry within you...
How double-strand DNA breaks are repaired
By: Alicia M Prater PhD
Breaks in the DNA strand due to exposure to damaging agents can occur across one (single strand break, SSB) or both strands (double strand break, DSB). Types of environmental damage that can induce chromosomal damage of this type include ionizing radiation, such as UV irradiation...
DNA mismatch repair explained
By: Alicia M Prater PhD
DNA is the genetic material of human cells. The sequence is made of four nucleotides that pair with one another via hydrogen bonds in the center of the double helix. The four nucleotides are adenine, guanine, thymine, and cytosine. Adenine is always paired with thymine...
Nucleotide excision repair explained
By: Alicia M Prater PhD
Deoxyribose nucleic acid, more commonly known as DNA, is the genetic material in human cells. The integrity of the nucleotides, or bases, that make up the sequence is important for proper cell function. Mutations to the chemical structure of the bases, caused by a number...
DNA base excision repair explained
By: Alicia M Prater PhD
Deoxyribose nucleic acid, known more commonly as DNA, is the genetic material of human cells. The integrity of the bases, or nucleotides, that create the DNA sequence is important for proper cell function via the transcription of proteins. Mutations to the chemical structure of...
DNA repair mechanisms
By: Alicia M Prater PhD
Deoxyribonucleic acid (DNA) is the genetic material of human cells. Changes in the DNA can disrupt cell function and result in disease, including cancer. Types of alterations include damage due to environmental effects and mistakes made during replication. Strand Breaks Environmental damage, including ionizing radiation...
