1) A.) The specific DNA changes caused by the delta F508 mutation, include a production of the abnormal cystic fibrosis protein. This mutation can only be inherited if both genes in pair of DNA carry the cystic fibrosis mutation. The specific mutation functions as a chloride channel, that has an abnormal amount of salt and water balance. Normally a chloride channel would help to maintain the right balance salt and water inside a cell, but those mutated with F508 mutation, are imbalanced causing…

Cellular Metabolism: Deoxyribonucleic Acid (DNA) is replicated when enzymes begin to unzip the DNA. The enzymes do this by breaking the hydrogen bonds that are between the pairs. After this occurs, the unpaired bases are now free to bind with other nucleotides. They may only bind if the nucleotides have the appropriate complementary bases. DNA polymerase now attaches DNA nucleotides to one end of the growing strand of nucleotides. Now there are two DNA molecules, each has an original nucleotide…

them. As the understanding of genetic code grew, people began to hope for healthier lives and an end of inherited diseases. Although the fear of scientists playing god grew as well. This simple molecule was now basic unit of creation, and another pair of scientists were looking to find how its structure worked. Rosalind Franklin and Maurice Wilkins(bottom photos) worked on tried to piece together the structure of DNA through pictures that were taken through x-ray crystallography, using the…

between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins. DNA A. adenine T. thymine C. cytosine G. guanine What is RNA ? A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine,…

and it becomes an enucleated egg cell. -The nucleus is removed because the nucleus contains the majority of the genetic information (DNA). -DNA has a double helix structure and it is made from many nucleotides -Nucleotides are made from a nitrogen base (Adenine, Guanine, Cytosine, or Thymine), a phosphate group, and a deoxyribose. -The DNA is stored in the nucleus as chromatin, but during cell division the DNA stored as chromatin condense into chromosomes. -The DNA initially condenses into…

The gene represents 0.08% of the human genome. The dystrophin gene represents 2.5 megabases worth of data. One mega base pairs (mbp) equals 1,000,000 bp. Additionally, the primary transcript for dystrophin is around 2,400 kilobases. One kilobase (kb) equals 1000 base pairs of DNA or RNA. Early diagnosis of DMD is the best current treatment for the disease. There is no cure for DMD. There is little data collected on the disease since it is…

A. Introduction Imagine yourself living with a medical condition that restricts you from eating certain foods that are rich in iron and foods that increase the absorption of iron. While it is impossible to completely avoid iron in your diet, even moderate amounts can be fatal in the long run, because your body absorbs more iron from the food that you eat than most people. For many years, hemochromatosis has been a mystery to medicine, and scientists all over the world have investigated the…

Flow cytometry results, Figure 3, demonstrate that the initial population of MDA-MB-231 cells contain the sub-population of cells with the desired surface markers, CD44+/CD24-/low/CD45-. The flow cytometry data showed only ~4% of the total cells represent the sub-population with the desired surface markers. In a study using flow cytometry to identify stem-like cells, not including CD45 in their experimental analysis of MDA-MB-231 cells and similar cell types demonstrate that 90% of the…

: Although the Vietnam War had nearly come to an end, all four sides had come to an agreement known as the Pairs Peace Accords it created a compromise, but it did not completely end all the conflict. The Paris peace accords demanded all of Americas troops to leave Vietnam and after that the fighting would be over but not all the conflicts are fixed just by stopping the fight. After the fighting, there were still conflicts in the state of Americas economics. The treaty had included the democratic…

(H+) donor A base is a proton (H+) acceptor EXPLANATION OF THE THEORY: Acids are proton donors and bases are proton acceptors. A hydrogen ion is the same thing as a proton since hydrogen consists of a proton and an electron. When hydrogen loses an electron all that is left is a proton. According to the Brønsted-Lowry theory of acids and bases, when an acid and a base react, a conjugate base and a conjugate acid will be produced. EXP: acid + base à conjugate acid+ conjugate base EXP: HCl…
