Introduction to nucleic acids and their structure [link]
What are nucleic acids? Nucleic acids are the carriers of genetic information In all living organisms the hereditary information is stored in deoxyribonucleic acid (DNA) which is a molecule formed by the repetition of nucleotides (making DNA a polymer) There are four different nucleotides in DNA which form a universal code |
What did Kossel discover about nucleic acid?
Kossel went on to show that nucleic acid contained purine and pyrimidine bases, a sugar and phosphate. Work in the 1930s from many scientists further characterised nucleic acids including the identification of the four bases and the presence of deoxyribose, hence the name deoxyribonucleic acid (DNA).
Who invented nucleic acid Chemis-try?
An important practical advance in nucleic acid chemis-try was the rapid and accurate synthesis of short oligo-nucleotides of known sequence. The methods were pioneered by H. Gobind Khorana and his colleagues in the 1970s.
Why do we study nucleic acids?
The study of nucleic acids, from their first identification as the genetic material is littered with landmarks in molecular biosciences, many of them marked with Nobel Prizes. Since Watson and Crick proposed their structure of DNA our knowledge about DNA and how it works has expanded almost exponentially.
Who discovered DNA?
Friedrich Meischer discovered DNA in 1869, calling it nuclein (from its presence in the cell nucleus). Chemical Heritage , the magazine published by the Chemical Heritage Foundation, issued a special cover feature on Meischer's discovery, "Friedrich Miescher: The Man Who Discovered DNA," (vol. 21, no. 2, Summer 2003).
