assignment is about how chromosomes separate and how cell division works through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin its bases

An example of modern forensics evidence is the use of DNA fingerprints. Sources of DNA include blood‚ hair‚ semen‚ saliva‚ bone and tissue. Each person has a unique DNA fingerprint. A DNA fingerprint is the same for every cell‚ tissue‚ and organ of a person. It cannot be altered by any known treatment. Consequently‚ DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings . An additional application of DNA fingerprint technology is the diagnosis of inherited disorders in adults

Computing Computer Science & Engineering DNA Computing Computer chip manufacturers have discovered that sooner or later the physical speed and miniaturization limits of silicon chip is bound to hit a wall‚ therefore they need a new material to produce faster computing speed with fewewr complexity. DNA‚ the material are genes are made of‚ is being used to built the next generation of microprocessor. A nascent technology that uses DNA molecules is to build computers that are faster

expressed in a cell or organism‚ one can acquire valuable hints to its function‚ for genes compile the genetic make-up of an organism and exploring the function of genes is helping to uncover the complexity of ourselves and of other forms of life (1). Significant developments have been made in gene monitoring techniques specifically in DNA microarrays which only very recently revolutionized genome expression analysis (1). Despite continuous improvements and modification to the technique‚ DNA microarrays

DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands‚ pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule

Qualitative Case Study Methodology: Study Design and Implementation for Novice Researchers Pamela Baxter and Susan Jack McMaster University‚ West Hamilton‚ Ontario‚ Canada Qualitative case study methodology provides tools for researchers to study complex phenomena within their contexts. When the approach is applied correctly‚ it becomes a valuable method for health science research to develop theory‚ evaluate programs‚ and develop interventions. The purpose of this paper is to guide the novice
