which is attributed largely to Gregor Mendel who lived from 1822 to 1884 and was considered to be a mathematical scientist who introduced the science of genetics. Observation During the period of 1858 to 1866‚ Mendel observed the different characteristics that where inherited by living creatures. He done this by breading garden peas in his monastery garden and analyzing the offspring of these mating. Construction of hypothesis From his observations Mendel was able to construct a hypothesis

GENE MUTATION‚TYPES OF MUTATIONS 1. Gene Mutation A Gene Mutation is defined as an alternation in the sequence of nucleotides in DNA. It can affect a single nucleotide pair or larger gene segments of a chromosome. Mutations cause changes in the genetic code which lead to genetic variation and the potential to develop disease. What causes Gene Mutation? → Gene mutations are most commonly caused as a result of two types of occurrences. 1. Environmental factors Ex) chemicals‚ radiation

Gene Cloning Clone: A group of identical cells or organisms To clone a gene: 1) Insert the gene into a vector that can carry the into a host cell 2) Ensure that it will replicate there 3) Insertion is carried out by cutting the vector and the DNA to be inserted with the same restriction endonuclease to ensure that both have the same "sticky ends" Vector for cloning the bacteria come from two major types: (1) Plasmids‚ and (2) Phages Recombinant DNA Technology A) It was developed in

But we soon find that with courage and determination Vincent can rise up and live his dream despite being “disadvantaged”. Vincent Freeman was born of a ‘faith birth’ also called a ‘God-child’. Throughout the film we find that this limits Vincent’s ability to reach his goal of working at Gattaca. Vincent is labelled as
