It has been more than 80 years to establish the double helix model of DNA structure since nucleic acids was found in cell. Ultimately DNA is confirmed the genetic material of life,so a key problem of life science research is solved. Therefore,researching into this period of history is of gr...
time.In 1860,Mr.Mendel discovered why we look the same as other people in our family.It is because of 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 ...
Function of DNA Why DNA is called a Polynucleotide Molecule? Read on to explore DNA meaning, structure, function, DNA discovery and diagram in complete detail. What is DNA? “DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic ...
aIn this technique of "gene chips", DNA corresponding to thousand of genes are arranged on small matrices ("chips") and probed with labeled cDNA from a tissue of choice. The information is then read by a device to be downloaded to a computer. 在“基因这个技术切削”,对应到一千的脱氧核糖核...
Later, scientists discovered that DNA was responsible for heredity and found that genes are the sequences in DNA that encode proteins and functional RNAs. It seemed that genomes were organized so that a given piece of DNA would encode a specific protein, and this is the way genes were ...
Genes Introduction to Genetics What is DNA? DNA stands for DeoxyriboNucleic Acid It is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus. “Blueprint of life” The main role of DNA molecules is the long-term ...
