Roles of microbes in DNA research Activities of microorganisms are very important to almost every sector of concern to mankind. From a perusal of the foregoing topics‚ one can find applications (uses) of microorganisms to agriculture‚ forestry‚ food‚ industry‚ medicine‚ and environment. The scope and significance of microbiology has enlarged manifold‚ particularly when importance of environment was realised globally and the word environment was used in a much wider sense in terms of totality to

Anne Holt DNA Profiling Introduction: DNA Profiling was authorised in the mid- 1980s. DNA is short for deoxyribonucleic acid. DNA accommodates a genetic code for each organism. DNA profiling is not just used for identifying fingerprints and such‚ it is also used for identifying any type of evidence that has DNA in it. Auspiciously‚ each DNA is unique‚ not even siblings have indistinguishable DNA‚ unless they are identical twins. USES OF TECHNIQUE: DNA profiling is used most often to solve crime

Using DNA in Science and Technology DNA is the blueprint for life‚ it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles‚ such as plasmids in bacteria‚ chloroplasts in plants‚ and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes‚ and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure‚ its sugar phosphate backbone‚ made up of deoxyribose and a phosphate

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

Using agarose gel electrophoresis is to separate and visualize the DNA fragment‚ which is produced by restriction enzymes . Introduction: The purpose of this experiment is to measure the size of the fragments of DNA and separate

Does DNA profiling in its current state offer foolproof identification? What needs to be in place for it to be error-free? Should all incarcerated criminals be forced to give samples? Should convicted juveniles? Should the general public be required to give a DNA sample? The pros of DNA profiling are that it can be used to quickly eliminate a suspect‚ saving time in searches for perpetrators. And it can provide compelling evidence to support a conviction and‚ most importantly‚ reduce the chances
