Determination of specific heat Capacity of a solid by electrical method Introduction Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies‚ heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius‚ different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the

information on what DNA replication looks like. The sources showed me what a strand of DNA looks like as well as giving me an explanation of what occurs during DNA replication. As my model is colour coded it makes it clearer as to what is occurring during each step in DNA replication as well as what each element is. It also clarifies what the external elements are when DNA replicates i.e. helicase‚ polymerase and DNA ligase. However‚ there are also limitations to my DNA replication model.

T DNA IN CRIMINAL INVESTIGATION 5Transportation and storage of DNA evidence is also extremely important. Whentransporting DNA evidence the officer should be aware that having the evidence in directsunlight can cause the evidence to become compromised (DNA Evidence‚ 2012). The officershould ensure that they do not place the evidence in an environment where it can get hot‚ insteadthey should place it in a cold environment to preserve it (DNA Evidence‚ 2012). It is importantthat the DNA evidence be

DNA TECHNOLOGY How is DNA technology used in law enforcement? There are many different ways it is used‚ but it is mostly used to solve crimes. Much like deaths‚ rapes‚ or even big robberies. DNA is a way to identify a person by: blood‚ hair‚ skin‚ saliva etc... That is why when people are trying to discover a murderer they are very careful when they are collecting evidence.That is why when something occurs‚ everything is blocked off‚ and only investigators could pass into the area

Since its discovery in the 1980’s‚ the application of DNA has been utilized in many ways. When Deoxyribonucleic Acid‚ or DNA is examined‚ a precise decoding of genetic information is revealed. With the exception of identical twins‚ every person’s genetic code (commonly referred to as a Genetic Fingerprint) is inherited and unique. From Maury advising men everyday on TV “You ARE the Father!” or “You are NOT the Father!” to learning the descendents of former slaves are related to President Thomas Jefferson

Included in DSM-IV-TR (4th.ed) the term cultural-bound syndrome denotes recurrent‚ locality-specific patterns of abnormal behavior and troubling experience that may or may not be linked to a particular DSM-IV-TR diagnostic category. Many of these patterns are naturally considered to be illnesses‚ or at least afflictions‚ and most have local names

process by which DNA turns into polypeptides is a complicated and long. Two main steps in changing the DNA into a polypeptide are transcription and translation‚ with transcription coming first. The process first starts in the nucleus of the cell. The DNA begins to unfold with the help of a helicase. During the transcription phase of the change‚ strands of DNA begin to unwind and the complementary mRNA is made or transcribed. The way they do this is by using the common pairs of DNA triplet bases (A-T

parts of a nucleotide and how they bond to form a nucleotide. The three parts of a necleotide are a carbon sugar‚ a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds. 2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent and hydrogen are as follows. hydrogen bonds‚ being easy to break‚ allow the DNA to break
