Fundamentals of Biochemistry in the Biotech Industry Maple Syrup Urine Disease: A Sweet Scented Killer Maple Syrup Urine Disease (MSUD) is a rare, potentially deadly disorder where the body cannot break down the three branched- chained amino acids (BCCA): leucine, isoleucine and valine. These amino acids are used to build proteins and when they are not being used they can be broken down and recycled in the cell. The complex that breaks these amino acids down is called BCKD (branched-chain…
DNA is the element of making an organism. It contains genetic information that can be applied to all kinds of functions required for living. DNA is a sequence of nucleotides which can be transcript to mRNA. When mRNA is formed, it can later on translate to tRNA where codon could be found. Codon is a set of nucleotide in tRNA which is directly related to the formation of amino acid. The combination of codon determines the characteristic of the amino acid. In other words, to make amino acids,…
a. Introduction Lujo Hemorrhagic Fever is caused by a bi-segmented negative RNA virus that is one of several viruses known to cause viral hemorrhagic fever. The Lujo virus is part of the Arenaviridae family, which consist of several viruses categorized into two groups. The Lujo virus is categorized in the “Old World” group, which signifies that the virus in question was found in the Eastern Hemisphere, specifically the continent of Africa. The majority of the arenaviruses categorized in the…
DNA purification: To get pure DNA to use, a silica membrane was used to collect the long DNA strands. We started by adding 5 volumes of PB buffer to 1 volume of each PCR reaction. We put column and the silica wafers into tubs and pipetted the DNA samples onto the wafers. We centrifuged the tubes for a minute and disposed of the waste. After that we pipetted 0.75 ml of buffer PE to the samples and spun it for another minute then disposed of the waste. The columns were added to the tubes and spun…
This is accomplished by adding salt and ethanol to a solution containing DNA or RNA. In the presence of salt (in particular, monovalent cations such as sodium ions (Na+)), ethanol efficiently precipitates nucleic acids. The purified precipitate can be collected by centrifugation, and then suspended in a volume of choice. PROTOCOL:…
sequencing and visualized by gel electrophoresis. It also can be cloned into plasmids. PCR is used in many fields of medicine, molecular biology research, medical diagnostics, and ecology. It is fast and inexpensive technique used to amplify DNA and RNA fragments by 107 times. The polymerase chain reaction was…
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…
DNA is our genetic code, it is permanent and unchangeable. Epigenetics are the mechanisms that influence DNA, it is the device that inhibits or increases our gene expression. Epigenetics can be influenced by many factors, for example nutrition and stress. Although the actual makeup of our genetic code isn’t changed by these factors, the extent to which the genes are expressed can be (Rettner, 2013). Epigeneticist Moshe Szyf highlighted the ways in which different behaviors can influence…
Gene traps are the plasmid or retrovirus-based vectors having a reporter gene that is only expressed when integrated in a functional gene. They were originally developed for the study of insertional mutagenesis in mouse. The gene traps were used to identify and characterize genes which were regulated by exogenous stimuli or during development process. The gene trap is a process which makes it possible to identify genes that gives rise to phenotypic effects when they are switched off, and also…
Thus, the genetic code is the basis of the central dogma of molecular biology. Central dogma is nothing but the flow of genetic information in all living cells including human cells from DNA to RNA to proteins. The central dogma There are three classes of sequential biopolymers that encode information: DNA, RNA, and protein. The central dogma of microbiology describes the ways in which information flows among these three classes: DNA replication (DNA to DNA), transcription…
