cells and analyze for presence of myosin light chain. Utilizing Western Blotting techniques and using specific antibodies helped to detect myosin light chain. The hypothesis was that proliferating myoblasts could be induced to initiate the differentiation process by depriving the cells of the necessary growth factors and that the differentiation is characterized by the expression of muscle-specific proteins. The results showed that that myosin light chain was not present. It was concluded that the cells

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

Literature Review and Project Proposal AS6P01 Title: DNA Profiling Techniques in Forensic Science Abstract Since 1985‚ DNA profiling in forensic science has become very important in this virtual era of technology and in the world of science that solves both major and minor crimes. Small traces of DNA are considered in all circumstances from how the DNA was collected to fully obtaining the profile in its significant form. Traces of sweat‚ blood and semen are the most common type’s evidence

What is gel electrophoresis? Gel electrophoresis is a technique that separates pieces of DNA (or other biological molecules) by size. Pieces of DNA in a test tube all look the same. DNA Gel Electrophoresis Gel electrophoresis separates pieces of DNA by size so that researchers can further analyze them BURST Training Session November 29‚ 2005 Once the DNA samples are loaded onto the gel‚ an electric current is applied to the gel. DNA is negatively charged due to all the phosphate groups in the

Extracting DNA from Wheat Germ Cells Criteria to be assessed CE Introduction: DNA is the abbreviation for deoxyribonucleic acid. DNA is found in the nucleus of every cell & it stores the information that makes up living organisms. It is a double helix of 4 nucleotides. It contains a code that allows the body to make up proteins. The nucleotides are Cytosine‚ Guanine‚ Adenine and Thymine. (1) Wheat germ comes from wheat seeds. The ’ germ ’ is the embryo‚ which is the part of

Introduction In a Grignard reaction‚ a Grignard reagent (R–MgX) adds to the carbonyl group in an aldehyde or ketone to form an alcohol (Figure 1). The reaction of a Grignard reagent with formaldehyde can be to synthesize a primary alcohol‚ with any other aldehyde can be used to synthesize a secondary alcohol‚ while the reaction with ketone is useful in the synthesis of a tertiary alcohol. Figure 1. General reaction mechanism of a Grignard Reaction The preparation of the Grignard reagent involves
