1. Plasmids Plasmids are closed circular‚ double-stranded‚ extrachromosomal DNA molecules which occur naturally in bacteria‚ yeast‚ and some higher eukaryotic cells‚ and exist in a parasitic or symbiotic relationship with their host cell (Lodish et al.‚ 2000) The main application of plasmids is as cloning vectors in gene cloning. In gene cloning‚ a fragment of DNA‚ containing the gene to be cloned is inserted into a circular molecule called the “vector” to produce recombinant DNA molecule. Plasmids

Out of the major galaxies‚ the Andromeda Galaxy is located nearest to our Milky Way. The Andromeda Galaxy is two million light years away from us‚ but it can be seen with the naked eye because it is very bright. In this galaxy there are over a hundred billion stars. It is known to be the brightest galaxy. The Andromeda Galaxy is a spiral galaxy and is part of the Local Group. It has a large star cluster in its heart and a very large hidden black hole deep in the core. The middle is very bright

Circuit Variables 1 Assessment Problems AP 1.1 To solve this problem we use a product of ratios to change units from dollars/year to dollars/millisecond. We begin by expressing $10 billion in scientific notation: $100 billion = $100 × 109 Now we determine the number of milliseconds in one year‚ again using a product of ratios: 1 year 1 hour 1 min 1 sec 1 year 1 day · · · = · 31.5576 × 109 ms 365.25 days 24 hours 60 mins 60 secs 1000 ms Now we can convert from dollars/year to dollars/millisecond
