Function Part 3 Cloning Cloning means making an identical copy of something In biology it can refer to A lab method in which researchers copy fragments of DNA A reproductive method in which researchers produce an exact genetic copy of an entire organism.

Ribose and deoxyribose. Lecture 1. An introduction to DNA Topology. DNA. DNA inside the . Nuclues. . The human cell contains 23 pairs of chromosomes. If we scale the cell nucleus to the size of Basketball then the DNA scales to 200km in length.. 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.. DNA GLOW Lab A new way to investigate DNA structure.
