Replication

real life example of obedience. This does, however, differ from Milgram’s work as it doesn’t necessarily cause harm to the patient. Therefore, when Milgram’s original experiment lacked ecological validity due to it having an ethnocentric bias, this replication can be used to argue the results do in fact have ecological validity. Another way that Milgram’s experiments lacked ecological validity is due to the experiments artificial lab-based research, which can cause unnatural behaviors due to the false environment. This is commonly known as ‘demand characteristics’ which is ‘’a subtle cue that makes participants aware of what the experimenter expects to find or how participants are expected to behave’’. However, there are benefits to using a lab such as being able to control a far larger number of variables which makes the results far more accurate whilst making it easier to replicate. This is exactly what happened and Milgram replicated his experiments in a more realistic environment, a rundown office building, and found that only 48% of people followed through. This got rid of the limitation of a lab setting by generalizing it to a real-life setting. So despite Milgram originally having poor ecological validity, through replications of his experiment the issue has been counteracted and fixed. This is also a common reason as to why most psychological research breaks the ethical code of deception, in an attempt to prevent the participant from finding out. To…

Replication Inhibitors Replication inhibitors interfere with DNA synthesis. There are many of these inhibitors, but they typically work via two main mechanisms. One of these mechanisms involves either disrupting molecules that are needed for DNA polymerization or those needed in order to initiate replication. The other mechanism is by interfering with replication checkpoints that are involved in regulating the replication process. These checkpoints sometimes do this by triggering certain…

Replication is defined as the action of copying or reproducing something. In context to psychology, it refers to the replication of a study to ensure that the findings are accurate. In these studies by ______ Zimbardo and ______ Milgram’s they also enforce generalizable data. This means that researchers can take their conclusions and apply them to the population as a whole. Milgram replicated his obedience study on two different populations, one was unpaid college student volunteers, the other…

North Andaman Islands (NAI) are one of the major island groups of Andaman and Nicobar archipelagos (Fig.1), consisting tropical rainforest encompassing varied species richness and diversity coupled with high endemism (Prasad et al..). As per Champion and Seth [year] the predominant forest types of the study area are Andaman Evergreen (EG), Andaman Semi-evergreen (SEG), Andaman Moist deciduous (MD), Littoral and Mangrove forests. Major part of the island is covered with SEG which is scattered at…

open the doors to a new realm that deepen our understanding of biological systems and promises a future that once was an abstract idea in science fiction novels. A challenge that my generation is facing is answering whether genetic modifications are ethical. Despite the ongoing debates, it is remarkable that this type of science is even possible, partially because of the universality of DNA. DNA is the common language of all living things. In order for an organism to reproduce, it must copy…

Prokaryote DNA replication is a semi conservative, bidirectional, template driven process. The phrase ‘semi-conservative’ refers to the fact that the newly synthesised double stranded DNA is made up of one parental (existing) strand, and one newly synthesised strand. The parental duplex is not ‘conserved’ as an entity. This was proved by the Meselson-Stahl experiment by replicating E.Coli in different mediums of of different Nitrogen isotopes. The results consisted of half of normal weight and…

Comparison chart Replication Transcription Purpose The purpose of replication is to conserve the entire genome for next generation. The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry. Definition DNA replication is the replication of a strand of DNA into two daughter strands, each daughter strand contains half of the original DNA double helix. Uses the genes as templates to produce several functional forms of RNA Products One strand…

In rolling circle replication, a nicking protein called relaxase identifies a specific sequence on the DNA and makes a “nick” or cut at that location. The nick is created by the protein and allows the DNA to unwind and continue the process. Once the DNA opens forming an open complex from there a lagging strand will develop along the 3’ template strand due to the polarity and orientation of the strands. A leading strand will emerge and DNA polymerase enlists nucleotides to pair with the exposed…

A. Eukaryotic cells store their genetic information in chromosomes made of DNA. This DNA is copied during interphase of the cell cycle. Replication is semiconservative, meaning one strand of the replicated DNA would be from the original molecule and one would be new. The parental strands serve as templates for the new strands. Replication can begin when helicase breaks the hydrogen bonds responsible for holding the two complementary strands together, ultimately causing the molecule to…

so important? Drs ezilabeth Blackburn, Jack Szostak and Carol Greiders discovery of telomeres and telomerases can be considered as one of the key milestones in our understanding of DNA replication in eukaryotes as they helped us figure out how the ends of linear chromosomes are replicated. There discovery of telomeres and telomerase did not only fil A DNA molecule is made up of two strands of polynucleotides which can be described as anti-parallel meaning one strand is moving from a 3’ to…
