Ribose and deoxyribose. Nucleic Acids. What do we know already?. i. . The nucleic acids DNA and RNA are polymers of nucleotides. Nucleotides consist of 3 parts. A 5-carbon sugar – ribose or deoxyribose. A phosphate group (acidic & negatively-charged). By the early 1900’s it was known that the chromosomes carry the genetic (hereditary) information. Chromosomes are made up of DNA (. deoxyribose. nucleic acid). They now needed to know the structure of DNA. The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein. Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein. Essential idea: The structure of DNA allows efficient storage of genetic information.. There is 2m of DNA in each human cell, however the most cells in the human body have a diameter of 10 . μm. . This DNA is divided in chromosomes and coiled around proteins called histones so that it can be efficiently stored in each cell's nucleus. The human genome project which has decoded the case sequence for the whole 2m of the human genome requires a data warehouse (pictured) to store the information electronically. This should give a good idea of just how efficient DNA is at storing information and why it needs to be so.. shapes and patterns. 조연우. Contents. DNA. DNA origami. The application of DNA origami.
