DNA bender: Cren7 & Sul7 DNA benders can introduce a bend in the DNA (Luijsterburg et al.‚ 2008). Many bends in the DNA automatically provide compaction of the DNA. Two important DNA bending proteins in crenarchaea are Cren7 and Sul7 (Driessen et al.‚ 2013). They are similar in structure‚ but they have different DNA binding regions (Zhang et al.‚ 2015). Cren7 and Sul7 can be methylated at several lysine residues (Guo‚ 2007). This PTM might be to regulate gene expression (Feng et al.‚ 2010)‚ although

DNA Typing The discovery of the structure of DNA opened the realm of DNA technology and changed the way in which crimes can be solved. This is due to the fact that many criminals often unwittingly leave their DNA at crime scenes and/or the DNA of victims is carried away on the clothes of their assailants (Saferstein‚ 2015). Thus‚ by using DNA it is relatively easy to place individuals at crime scenes and discover key evidence. Before the 1980s‚ the courts primarily relied on testimony and eyewitness

Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA fingerprinting

by hydrogen bonds they are molecules. (Hold DNA together) DNA Replication Said to be semiconservative In bacteria DNA replication proceeds simultaneously in both directions‚ away from the origin of replication. DNA is the template or genetic material of the cell‚ the info for building proteins and RNA is located in the DNA. The sequence of DNA that contains the info for a single protein or RNA is called a GENE. • Purpose – to replicate dna in preparation for cell divison and to provide

Biochemical Prospective of DNA polymerase in Replication Biologists and chemists have long recognized a relationship among DNA‚ RNA‚ and protein‚ and this recognition has guided a vast amount of research over the past decades and generations. The pathway of DNA to RNA and RNA to protein is conserved in all forms of life and is often called the Central Dogma. DNA functions as a storage molecule‚ holding genetic information for the lifetime of a cellular organism‚ and allowing that information

with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using a heat-shock system (Donahue and

The Normalized Difference Vegetation Index (NDVI) is widely used for monitoring‚ analyzing‚ and mapping temporal and spatial distributions of physiological and biophysical characteristics of vegetation (Gitelson‚ 2004). NDVI which is based on different radiation absorption by green biomass in Red and NIR wavebands is widely used for the assessment of the green plant biomass at ground‚ airborne and satellite levels (Marino et al.‚ 2014). Forests in urban stands tend to have lower stem densities‚

DNA Extraction Lab Purpose: To compare the amount of DNA extracted from two different species‚ despite using the same method. Hypothesis: I predict that the liver will produce a higher quantity of DNA than the strawberry. This is because I believe that animals have a higher DNA yield because our structure is more complex than a plant’s structure. Materials: -Sample of Strawberries -Zip lock bag -DNA extraction buffer -Cold ethanol -Glass rod -Double ply cheese cloth -Two test tubes
