Viruses have an amazing mechanism of propagation. They are inert in that they do not have the components to reproduce that cells usually possess. Yet they are extraordinarily successful in spreading themselves around. Here’s how.
The human organism contains threadlike, gene-bearing chromosomes, twenty three pairs of them. These chromosomes contain the complete heredity, including characteristics such as the color of the eyes, the hair and skin. One specific pair of chromosomes determines the sex or gender of the individual.
There is no clear cut answer to the origin of homosexual behaviour. Currently the consensus is leaning towards a largely genetic basis with a few environmental variables thrown in. It appears there is no single gay gene and no single environmental variable.
A landmark study is shedding light on an important aspect of our genetic and physical evolution. Scientists have discovered that a region of DNA once dismissed as junk may have contributed to the development of opposable thumbs and our ability to walk on two legs.
Time now for a tall story on the growing body of work on the genetics of height. There’s a whole suite of genes that will determine how short or tall you are, but environmental factors also play a big part in how you actually grow.
Chromosomal disorders are caused by an absence, excess or abnormal arrangement of 1 or more chromosomes. The defects are there from birth; while some are harmless many cause severe disorders. This article is a brief look at some of the conditions caused by changes in their structure.
They are destructive little pests and the bain of the lives of farmers and gardeners. But weeds are finally proving to be helpful - to geneticists. Understanding the genetic code of weeds is going to have a big impact on crop yield and quality - and human medicine too!
Finding a gene is a vital first step in understanding and eventually trying to cure or treat a genetic disorder. With 3164.7 million nucleotide bases in the human genome, just how do scientists locate a gene?
Does cheating have a genetic basis? Is it possible that if you have a specific variant of a gene (a monogamy gene) you may be more prone to cheating and be less faithful in your relationships? A new study has some startling answers.
Have you been turned down for health insurance or employment because of a genetic mutation in your medical history? You’re not alone. Read more about genetic discrimination and how it affects people with a mutation of the BRCA1 gene.
