All living things are based upon one thing that unites us all‚ DNA. DNA‚ standing for Deoxyribonucleic Acid‚ is commonly compared to a blueprint. This blueprint orders a highly specific set of corresponding bases‚ which in turn codes for an amino acid. However‚ this specificity comes at a very high risk; a single error in a base could code for a completely different amino acid‚ causing a mutation that could devastate the organism. Recently‚ scientists have discovered a new method to edit and repair

Fragile X Syndrome is a genetic condition that causes intellectual disability‚ behavioral and learning challenges‚ and various physical characteristics. FXS is caused by changes in the fragile X mental retardation 1 (FMR1) gene. The FMR1 gene makes a protein called fragile X mental retardation protein (FMRP). FMRP is needed for normal brain development. People who do not produce this protein have FXS. The FMR1 gene is located on the X chromosome; we all have 46 chromosomes in all of our cells. Out

In the early 1950’s‚ when Alfred Hersey and Martha Chase were preforming experiments to determine which material in a cell was the hereditary material‚ the scientific community was much different that it currently is. To begin‚ female scientists were discriminated against heavily‚ especially if that woman was not a full-time researcher or also taught students (Gur-Arie). Unfortunately‚ this problem is still present today to a lesser degree. Also‚ scientists were often recruited to top research facilities

The structure of DNA and the effect of point mutations (25 MARKS) Deoxyribose Nucleic Acid (DNA) is a polynucleotide molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Most DNA molecules are double stranded helices‚ consisting of two polynucleotide strands made up of simpler molecules known as nucleotides. A nucleotide is made up of an organic nitrogenous base‚ a deoxyribose sugar and

Claudius Caesar’s Death The Roman emperor Claudius Caesar had an appetite for mushrooms. Historians believe that Caesar’s wife‚ Agrippina‚ wanted to poison him. She mixed into his favorite dish of mushrooms a few of Amanita caesarea‚ a poisonous species. These mushrooms were able to block enzymes responsible for transcription. For the first 10 hours after eating the mushrooms Caesar seemed well. After 15 hours his liver cells stopped functioning. He then showed signs of nausea‚ diarrhea‚ and

Evolution‚ Genes & the Environment Variation is when you refer to genes; it means that there is a large variety of phenotypes‚ alleles and genotypes which can sometimes cause genetic variation. This results in different physical characteristics. Some examples of variations in humans are eye colour‚ hair colour and gender. Variations caused by the environment are the climate (tanned/pale skin) this is affected by the environment as the sun comes in contact with your skin and will darken it‚ the

IVD Antibody Development Services for PPWD1 Marker PPWD1: Cyclophilins consist of one of the three classes of peptidylprolyl isomerases discovered in all prokaryotic and eukaryotic organisms‚ together with viruses. Most of the seventeen human cyclophilins with the catalytic domain are in tandem with other domains‚ but many particular functions of a specific cyclophilin or its relevant domains remain unclear. The structure of the isomerase domain from a spliceosome-correlated cyclophilin‚ PPWD1 which

Good morning everyone‚ Genetics is the study of how living organisms pass on traits to each generation. It also explores the variations in every make-up of cells. Every living organism contains instruction manuals inside of their body. These instruction manuals are called genes. (Medicine‚ What is a gene?‚ 2015)Genes lie in long strands of deoxyribonucleic acid (DNA) called chromosomes. DNA containing genes form structures call chromosomes. Humans have 23 pairs of chromosomes. Chromosomes are made

DNA and genes are always changing due to many chromosomal changes such as inversion‚ deletion‚ insertion and translocation. However‚ there is an organelle in the human body that holds its own genome and occasionally has mutations‚ this organelle being the mitochondria. The mitochondrial is a semi-autonomous organelle that is believe to have arisen from free-living bacteria this is called the endosymbiotic theory. The endosymbiotic theory is the belief that long ago‚ a bacterium with a nucleus had
