Alu insertion polymorphism by PCR Introduction Alu elements have been accumulated in human genome throught mankind evolution‚ reaching over 1 million copies in genome. They are short‚ and repetitive DNA fragments found in primates. Each Alu element is known to have 300 base pairs in length. DNA repeats contribute to partial gene deletion or duplications in many cases of hereditary diseases.Alu insertion polymorphisms consists of absence or presence of Alu elements at a particular chromosomal location

sequence of DNA bases (nucleotides) made up of short segments of 1-6 bp repeated in more or less uniform tracts up to ~102 bp long. They are classified as mono‚ di‚ tri or tetra tandem repeats. II. Background information In 1989‚ it was studied in human and was found to be common in plants and animals. Variation in the number of repeats in a microsatellite arises due to DNA-polymerase errors during the DNA replication process. During DNA replication‚ DNA-polymerase moves along a DNA sequence

Sam Sheppard trials On July 4‚ 1954‚ the wife of a handsome young doctor‚ Sam Sheppard‚ was brutally murdered in the bedroom of their home in Bay Village‚ Ohio‚ on the shore of Lake Erie. Sheppard denied any involvement in the murder and described his own battle with the killer he described as "bushy-haired." Starting on the day of the murder‚ the media began to attack Sheppard on any occasion they could. Stories were obtained in unethical‚ and nearly unlawful ways. Even though they

Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory‚ who is one individual that contributed to modern genetic analysis? What did this person contribute? - The DNA Analysis Technique is the best choice because no two individuals have the same DNA. This makes it easy to determine a match between the person the blood came from and the blood sample. Alec Jeffrey’s came up with the first genetic profile in 1984. Jeffery’s invented the PCR‚ also known as
