Extraction is a method used for separating and isolating materials. A compound is pulled from solvent A to solvent B and in this case‚ both solvents are miscible. These two concepts are not capable of mixing together; when they are mixed together‚ they form a bilayer. This can be seen when mixing oil and water together. When thinking of extractions‚ one can picture how coffee gets extracted. The flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution

DNA Sequencing As of last few weeks‚ the transformation lab is performed to convey and purify a given protein. However after further research scientists found out that Transformation is not only used to purify protein but also to find out contents that are stored in a given plasmid. The objective of the lab that is to be performed involves a procedure that determines the identity of an unknown gene replicated in a plasmid. To begin this procedure two to four colonies of bacteria is added to two

DNA Cloning ~ The Future of Science DNA Cloning DNA cloning is the process where an exact replica of an organism is produced. Some scientists have already produced clones of animals; Dolly the sheep is one of the many examples of DNA cloning. Cloning is a natural process‚ many living things only need one parent to reproduce‚ this process is called asexual reproduction; for example single-celled bacterium use this process. The new bacteria inherits its genes from only one parent‚ this means

DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication. Cellular proofreading and error-checking

DNA Barcoding Click on the following link and view the background on DNA barcoding: https://www.dnalc.org/resources/animations/dna-barcoding.html 1. What is a DNA barcode? DNA barcoding is a fast accurate method of identifying plants and animals‚ or products made from them. DNA barcode is DNA sequence that uniquely identifies each species of living things. Short DNA sequences are used to identify species by comparing them with the known barcodes in large databases. When you get to the section where

DNA fingerprinting is a method that compares the fragments of DNA. DNA fingerprinting was first invented to detect the presence of genetic diseases. Today‚ DNA fingerprinting is used in different ways. DNA is analyzed using a Southern Blot‚ which allows scientists to observe the base pair patterns. DNA fingerprinting can be used in a few different ways. First‚ to find out if the child belongs to a person DNA fingerprinting may be used. When a child is born‚ it inherits the VNTR’s from the father

DNA and the Gene: Synthesis and Repair 1) Watson and Crick elucidated the structure of DNA in 1953. Their research built on and helped explain the findings of other scientists‚ including ________. A) X-ray diffraction studies by Rosalind Franklin and Maurice Wilkins. B) Chargaff’s rules: C = G and T = A. C) Scientists who recognized that a nucleotide consisted of a sugar‚ a phosphate‚ and a nitrogen-containing base. D) All of the above were important considerations in the elucidation of

DNA and Evidence DNA is one of the most important roles to evidence and in a criminal case. It helps to prove a convict guilty or help those wrongly accused or convicted. DNA stands for deoxyribonucleic acid. Just about every cell contains DNA. The DNA that’s in people blood is also the same DNA in people’s hair‚ bone‚ saliva‚ skin‚ tissue and everything else. What’s great about someone’s DNA it does not ever change throughout their life. DNA was first used as a way of finding out paternity so
