How DNA Works

DNA carries all information about your physical characteristics, essentially determined by the protein. Therefore, the DNA contains instructions for making the protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides specifying how to make a single protein). Specifically, the sequence of nucleotides within a gene specifies the order and type of amino acids that must be combined to produce a protein.

Protein storage protein (albumin in egg white, iron storage ferritin in spleen, etc.)

Hormone - cell chemistry messenger (including insulin, estrogen, testosterone, cortisol etc)

The specific sequence of amino acids in the chain causes a protein to be different from other proteins. The sequence is encoded by DNA, one of which encodes a protein

How does DNA code protein information? There are only four DNA bases, but there are 20 amino acids that can be used for proteins. Thus, three nucleotides are sufficient to specify 20, (4 × 4 × 4) (three base codons have 64 possible modes for the designation of 20 amino acids to the product protein (Codon). One of the 64 possible codons, only 20 amino acids, one of the genetic codes in some replications, the gene sequence of the codon in the given sequence of amino acids in the protein is the amino acid 100 It can be required between -100. One thousand codons designate a given protein (300 to 2000 nucleotides) Each gene contains a codon (start codon) that specifies gene and stop (stop codon)

After work DNA (below) explains how arguments are indicated. The DNA of living cells has a term that can effectively be used to describe the understanding of computers, computing environments and research. I can not say that there is a CPU that faithfully executes the for loop! But I say that we have all the elements we use for programming.

Recently, the key to developing new biotechnology was to discover the structure of DNA in 1953. Since then, people have a lot of understanding about DNA. In the 1970s and 1980s, a number of techniques for processing DNA were developed, which helped us to sequence the genome from many organisms. This includes the sequence of the human genome announced in 2003 after more than 10 years of research. Since biotechnology uses parts of living things, they often cause moral or legal problems. Should you clone an animal, treat the disease with embryonic stem cells, or infect an organ from a pig to a human? Use of this article, follow the student's activities to influence the impact of biotechnology on society encouraging classroom discussion and investigate the impact of biotechnology on society. This activity is the introduction to biotechnology Please use our online quiz - it has a large amount of resource treasure hunt

In the past decade, stem cell research has become almost visible commitment biological science and the most controversial performance similar to the 20th century, 1970s and 1980s, 1990s or recombinant DNA research and biotechnology human genome project I will. For controversial human embryonic stem cells, the term "stem cell" is widely recognized, it represents a decisive problem for national and local politicians. For biologists, "stem cells" have precise meanings, not only human embryos of political attention. Many specialized cells of animals and humans develop through ordered processes, cell division and differentiation.
