1. How DNA replication takes place? DNA replication occurs within the interphase‚ In this phase two strands of DNA serve as templates for new DNA strands that are forming. As the DNA separates a replication bubble is formed‚ this is where two replication forks are formed that grow in two directions. DNA polymerase creates new strands as nucleotides are added individually to each strand. As each nucleotide pairs itself to the complimentary nucleotide on the opposite strand‚ new DNA molecules are formed

The two navy officers shown at left are identical twins. Why do you think identical twins look so similar? Identical twins look so similar because identical twins have the same genetic makeup‚ meaning‚ the same DNA (same nitrogenous bases). This is because

their 1953 Nature publication‚ Watson and Crick announced their landmark discovery: DNA exists in the form of a right handed‚ three-dimensional double helix. They described their DNA model as two DNA strands connected by hydrogen bonds between complementary bases. Adenine bases are always paired with thymines‚ and cytosines are always paired with guanines. Watson and Crick identified the anti-parallel configuration of DNA strands; each 5’ end of one strand is paired with the 3’ end of its complementary

Date: 09/21/2012 Result The purpose of the experiment is to measure the amount of DNA extracted from a strawberry. In the experiment‚ we measured the absorbance of different concentrations of Methylene Blue. The data collected by our group is presented on Figure 1 and the average absorbance measured by whole class is stated on Figure 2. Table 3 shows the measurement on the amount of strawberry DNA extracted. In Figure 1 and Figure 2‚ the data will be presented Standard Curve Graph. The

analyze an extract from a play "The man of destiny" by George Bernard Shaw‚ an Irish playwright‚ who was mostly talented for drama. He wrote more than 60 plays. Nearly all his writings are devoted to the social problems‚ but have a vein of comedy which makes their stark themes more palatable. The fact of his being the only person to be nominated both a Nobel Prize in literarture and an Oscar proves him to be a very talented person. "The man of destiny" is a drama and drama is a kind of a genre which

John O’Sullivan‚ a New York journalist‚ is known to be the founder of the idea of Manifest Destiny‚ or the idea that the United States was destined to conquer the land given by God. Ever since the summer of 1845‚ when O’Sullivan had first published the idea‚ most of the American population was hooked on further expansion. Because the majority of the US population was in favor of Manifest Destiny when the US was given the option of annexing‚ or accepting‚ Texas the US accepted. While this acceptance

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

Extract DNA from Anything Living |[pic] | |Introduction: [pic] Since DNA is the blueprint for life‚ everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders‚ produce DNA fingerprints
