The aim of this experiment was to identify three mystery plasmids based upon their characteristics; such as size‚ antibiotic resistance‚ lacZ profile and conjugative properties. The results obtained showed that plasmid number2 was the pDSK519 plasmid and its size was 26229.58 Bp. Plasmid pDSK519 also was found to be resistant to kanamycin only and it possessed the LacZ gene. pDSK519 had the oriT gene but it did not have the tra gene. Plasmid number 22 was found

& Koella‚ 2007). The impressive diversity of humans in the planet establishes that each human is unique in their traits and characteristics. Those traits describe our genotype‚ the complete inherited makeup of an organism (Mossler‚ 2011). The genes of both parents play a crucial role in the genotypes and phenotypes of a human being; this predisposition will also be marked by environmental factors that will determined the condition of a child. In the complex elaboration of humans‚ even genetic

Chapter 15 The chromosomal basis of inheritance Key ideas: 1) Mendelian Inheritance has its physical basis in the behavior of chromosomes during sexual life-cycle. 2) Morgan traced a gene to a specific chromosome. 3) Linked genes tend to be inherited together because they are located on the same gene. 4) Independent assortment of chromosomes and crossing over produce genetic recombinants. 5) Geneticists use recombination data to map a chromosome’s genetic locus. 1900 Biology finally

The three popular aspects of biotechnology are IVF‚ Gene Therapy and Cloning and will be covered in relation to the future of us humans. One example of biotechnology is IVF (In Vitro Fertilization) which is a method where an egg is fertilised by sperm outside the body. This process takes several weeks

Geneticists can now determine whether the Treacher Collins gene is a new mutation or one that has been passed on. There are new studies being done to see about the possibilities of there being other genes that could be involved with this syndrome. Treacher Collins Syndrome is believed to be caused by a change in the TCOF1 gene on chromosome 5

the different factors that go into natural selection. These factors were things such as: fertility‚ the complexity of genes‚ the use of natural selection versus not using it‚ and the rate of mutation. All of these things would then affect the amount of generations it would take to get the “target phrase.” This target phrase was used as a tool to understand the complexity of some genes compared to the simplicity of others. The first chapter in Dawkins’ book‚ “The Blind Watchmaker‚” correlates the most

The transgenic species affecting a gene pool in a certain population is a severe impact in itself; but genes from genetically engineered organisms have the potential to move from their original release point to affect the gene pool of other plants and animals.

An overview of several important discoveries on the nature of gene: In the 1860’s Mendel discovered the discrete units of inheritance. 1880’s: discovery of chromosomes. 1903: discovery of homologous chromosomes. 1909-1911: discovery of crossing over. 1911: discovery that genes could be mapped in order along length of chromosomes. 1944-1952: discovery of DNA as genetic material. 1953: Watson and Crick discovered DNA
