Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Summary: West African Colony Of Liberia - Restriction Enzyme Digestion. Preparation of DNA for traditional cloning methods is dependent upon restriction enzyme digestion to generate compatible ends capable of being ligated together. The DNA to be cloned can vary widely, from genomic DNA extracted from a pure bacterial culture or a mixed population, to a previously cloned gene that. Temperature: Most digestions are carried out at 37°C. However, there are a few exceptions e.g., digestion with Sma I is carried out at lower temperatures (~25°C), while with Taq I at higher temperature i.e., 65°C. Buffer Systems: Tris-HCl is the most commonly used buffering agent in incubation mixtures, which is temperature dependent. Most. One of the most popular strategies is to perform double digests of both the insert and vector for directional cloning. In the following example (Figure 3A), two enzymes that generate non-compatible ends (EcoRI and KpnI) are used. Doris Lessing Group Minds
