DNA Packaging: Nucleosomes and Chromatin By: Anthony T. Annunziato‚ Ph.D. (Biology Department‚ Boston College) © 2008 Nature Education Citation: Annunziato‚ A. (2008) DNA packaging: Nucleosomes and chromatin. Nature Education 1(1) Each of us has enough DNA to reach from here to the sun and back‚ more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? The haploid human genome contains approximately 3 billion base pairs of DNA packaged

and later reeds‚ were made into baskets to store food surpluses. Some foods could then be saved for future meals and less time was needed for seeking and gathering food. Paper may be the oldest form of what today is referred to as "flexible packaging." Sheets of treated mulberry bark were used by the Chinese to wrap foods as early as the First or Second century B.C. During the next fifteen hundred years‚ the paper-making technique was refined and transported to the Middle East‚ then Europe and

used. They were also self-sufficient‚ so there was little need for packaging of goods‚ either for storage or transportation. When containers were needed‚ nature provided gourds‚ shells‚ and leaves. Later‚ containers were fashioned from natural materials‚ such as hollowed logs‚ woven grasses and animal organs. As ores and chemical compounds were discovered‚ metals and pottery were developed‚ leading to other packaging forms. Packaging is used for several purposes: • Contain products‚ defining the amount

The Theory of Storage THE THEORY OF STORAGE. "THE SUPPLY OF STORAGE REFERS NOT TO THE SUPPLY Of STORAGE SPACE BUT TO THE SUPPLY OF COMMODITIES AS INVENTORIES. IN GENERAL A SUPPLIER OF STORAGE IS ANYONE WHO HOLDS TITLE TO STOCKS WITH A VIEW TO THEIR FUTURE SALE‚ EITHER IN THEIR PRESENT OR IN A MODIFIED FORM. SINCE PRODUCTION IS NOT STABLE FOR ALL COMMODITIES ESPECIALLY ARGICULTURAL CONSUMERS DEMAND THAT THE STORAGE FUNCTION BE SO PERFORMED THAT THE FLOW OF COMMODITIES FOR SALE WILL BE MADE RELATIVELY

Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)

economically viable alternative to other storage networking solutions. Justify this statement. Ans- DAS provides an economically viable alternative to other storage networking solutions as- • DAS configuration is simple and can be deployed easily and rapidly. • Setup is managed using host-based tools‚ such as the host OS‚ which makes storage management tasks easy for small and medium enterprises. • DAS is the simplest solution when compared to other storage networking models • Requires fewer

Executive Summary The United States wine industry is a 12 billion dollar industry and is composed of 7‚000 wineries and around 1‚800 different companies. The three major companies within the industry are Constellation brands‚ E&J Gallo‚ and The Wine Group Inc. The industry has made its way through the economic crisis at a better rate than some of the other U.S industries however in order for them to continue to see any type of growth it is important that they acknowledge their issues and find

Data stored in backing storage is permanent so it is NOT lost when the computer is turned off. It is always slower to access data from backing storage than from internal memory.
