In February 2001 it was announced that the genome contains not 100,000 genes as originally expected but only 30,000. This startling revision led some scientists to conclude that there are simply not enough human
The number and order of these four bases determine for example, whether you are a chimp, a cow, a banana, or a human. Most genes are recipes for making specific proteins, these recipes are passed down from parents to children, from generation to generation. When someone says “You have y...
Alleles are a set of two or more genes that are responsible for the formation of genetic variation among phenotypical and physiological traits observed in organisms. An example of an allele is the formation of different blood groups of different individuals. In addition, it can also be observed...

neuroscience; of the 30–40,000 genes encoded by the human genome, about one third are involved in building the brain, but explaining how they do so remains a distant goal. Nevertheless, with the publication of the draft sequence and associated analyses, the next steps are coming into ...
James Watson, leader of the Human Genome Project, claimed:“In large measure, our fate is in our genes.” That may be true for many of our physical and biological traits, but not to worry. You do still have some freedom to make choice in your life. Even if those choices are… less...
What genes are responsible for embryonic development? How does gene editing impact human evolution? What is gene theory? What is phasing in biology? What are the fixed alleles in the human species? What kinds of somatic cell gene mutations exist?
It is because of the small things called “genes(基因)” in our body. In 1953,two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language.In 1961, two other scientists found the first“word"that they co...
This is par- ticularly true for neuroscience; of the 30–40,000 genes encoded by the human genome, about one third are involved in building the brain, but explaining how they do so remains a distant goal. Nev- ertheless, with the publication of the draft sequence and associ- ated ...
