We each have a unique genetic (基因的,遗传的) make-up. Every cell of your body has the same set of about 100 000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have...
The hereditary material of all multi-cellular organisms is the famous double helix of deoxyribonucleic acid (DNA). This contains all of our genes. DNA, itself is made up of four chemical bases, pairs of which form the "rungs" of the twisted, ladder-shaped DNA molecules. These four molecule...
Gene editing is the ability to manipulate – or control – DNA. And in case you didn'tknow, DNA is short for deoxyribonucleic acid – this is a substance in the cells of animalsand plants that contains genetic information. And a gene is...
And genes aren’t just in humans — all animals and plants have genes, too.Genes hang out all lined up on thread-like things called chromosomes. Chromosomes come in pairs, and there are hundreds, sometimes thousands of genes in one chromosome. The chromosomes and genes are made of DNA, wh...
centres on the character Vincent Freeman, who wasn't genetically engineered, but is able to buy the genetic identity of another man in order to pursue his dream of travelling into space. The film's title uses the letters G, A, T and C, which are the four chemical codes making up DNA...

As shown in this diagram, the NOTCH2NL genes arose through a duplication event in a common ancestor of humans, chimpanzees, and gorillas, but only became functional genes in the human lineage.

It's time to bust the lid off some common misconceptions about recessive genes. First of all, when you hear the term "recessive genes," you probably think of ...
make proteins. These so-called epigenetic changes can switch genes on or off, or just turn them up or down. Epigenetic changes are made to our DNA throughout life and are thought to be influenced by what we eat, how much we exercise, whether or not we smoke, and other lifestyle ...
