GENE REGULATION: Gene regulation is the method of limiting the genes in the cell’s DNA, which are expressed. It is utilize to form a functional manufacture for an example protein. Various cells in a multi cellular organism might express very difficult group of genes. Although, they consist the similar DNA. Human having over ten thousands of genes in their genome. Cells are expressed the all genes. Even an organism as simple as bacterium must carefully regulate gene expression. Ensuring that the…

Bioinformatics is a study that focuses on the collection and analysis of biological information using information from sequences of DNA, RNA, and proteins. This field focuses on how to make predictions about biological systems and analyze data to provide more insight on how living organisms function and how its genome relates to its biology. Following the determination of the insulin sequence, Frederick Sanger realized that manually comparing several sequences was impractical (Moody 2004)).…

into DNA of SV40 was truly a paradigm shift. No longer was the study of molecular biology purely observational, Dr. Berg’s discovery gave scientist the traction to synthetically modify and transduce foreign DNA into a desired host. Because of this, not much was known about this type of genomic modification. Except for the knowledge that SV40 DNA possessed the ability to insert its genetic information into a host genome and the discovery of Daniel Nathans’ that restriction enzymes cleave DNA at…

DNA organization within cells is a complex and sophisticated process. This high level of complexity is due to the hundreds of thousands of interactions that can be enabled through organization. It is a known that promoter elements and enhancer elements work in unison to regulate gene expression. Often times enhancers are found hundreds of kilo-bases away from their interacting promoter elements. These enhancers initiate promoter activation via interactions amongst transcription factor binding…

Every living cell contains genetic information in the form of chromosomal DNA. Chromosomes can be circular in prokaryotic, or simpler single-celled organisms such as bacteria, but tend to be linear in more complex eukaryotic cells. The replicon, or the enzymatic complex that replicates DNA has limitations on its efficiency and capabilities. For example, eukaryotic DNA polymerase requires a short RNA primer to begin replication on the lagging strand, because of this replication cannot continue…

PCR Amplification Desired DNA was amplified in 200µL PCR tubes. WtfolA PCR tubes contained 0.1584ng/µL wildtype folA derived from pMAC1-wtfolA (biochemistry teaching labs), 0.2µM forward primer (MOBIX, CGGCAGCCATATGATCAGTCTGATTGCGGC) and 0.2µM reverse primer (MOBIX, GTGCTCGAGCCGCCGCTCCAGAATCT). MutfolA PCR tubes contained 4ng/µL mutant folA derived from pET28b-mutfolA (biochemistry teaching labs), 0.2µM forward primer (MOBIX, GACGGACACATATGATCAGTCTGATTGCGGCG) and 0.2µM reverse primer (MOBIX,…

In Vitro Fertilization and Cas9 By Cody Dyess ENC1102 Professor Rivers 11/20/17 Outline I) Introduction A) Gene therapy B) Thesis statement: Cas9 should be used for gene therapy in in vitro fertilization to stop genetic disorders from developing in children. II) Defining what Cas9 is III) The history of Cas9 IV) Defining in vitro fertilization and its history A) Discovery B) Implementation V) Merging Cas9 with in vitro fertilization VI) Results of Cas9 against disease VII) Cas9’s…

process of altering an existing gene in the DNA and inserting it into cells in an organism to fix genetic disorders or diseases. In humans, gene therapy is the process in which some of the defect cells or the cells carrying the disease are removed from the body (eg. lung cells in a Cystic Fibrosis patient) in order to harvest their DNA. The base sequence of their DNA is then altered to remove the genetic disorder by deconstructing and reconstructing DNA through techniques such as PCR, ligation…

PCR method. Using 1 l DNA extracted from Rotorod sampler as a template, 1X PCR standard buffer (New England Biolabs, Ipswich, MA), 200 M dNTPs (New England Biolabs), 400 nM each primer and 2.5 unit Taq polymerase (New England Biolabs) 20L PCR mix were prepared. For initial denaturation one cycle 94°C was applied. After that 35 cycles of , 94 °C for 45 seconds (DNA denaturation) 54 °C for 45 sec (oligonucleotide primer annealing), and 72 °C for 1 min (Taq polymerase extension) were applied…

because of the DNA it contains. In fact, each human contains approximately six feet of DNA which is tightly packed and highly organized by proteins, the majority of it stored in the nucleus [1]. With this DNA, the nucleus produces needed proteins which are then used for cell growth, reproduction, and the overall functioning of the cell [2]. Furthermore, the nucleus is bound by a double layer membrane called the nuclear envelope. Similar to the plasma membrane, the…
