Question 1

How does a PCR work in detail?

Accepted Answer

PCR, or Polymerase Chain Reaction, is a method used to make millions of copies of a specific DNA segment. Imagine you have a tiny fragment of DNA, like a small book chapter you want to read over and over. PCR is like a photocopier for that chapter. You start by mixing the DNA with a few ingredients: primers (short DNA sequences that match the start and end of your chapter), nucleotides (the building blocks of DNA), and a special enzyme called Taq polymerase that can withstand high temperatures and is essential for building new DNA strands. The process involves heating the mixture to separate the DNA strands, cooling it so primers can attach to the ends of your target DNA, and then slightly warming it so the Taq polymerase can build new DNA strands. Repeating this heating and cooling cycle amplifies the DNA, giving you enough copies to study in detail.

Question 2

What does a plasmid do and why was it necessary?

Accepted Answer

A plasmid is a small, circular piece of DNA commonly found in bacteria. Think of it as a tiny extra book inside the bacterial cell that carries bonus information, like antibiotic resistance or special metabolic capabilities. In genetic experiments, plasmids are used as vectors, which means they can transport new genes into cells. This is essential for genetic engineering because inserting your gene of interest into a plasmid allows the gene to be copied and expressed inside the host organism. Plasmids are like delivery trucks carrying important cargo (your gene) into a factory (the host cell) where it can be used.nces that match the start and end of your chapter), nucleotides (the building blocks of DNA), and a special enzyme called Taq polymerase that can withstand high temperatures and is essential for building new DNA strands. The process involves heating the mixture to separate the DNA strands, cooling it so primers can attach to the ends of your target DNA, and then slightly warming it so the Taq polymerase can build new DNA strands. Repeating this heating and cooling cycle amplifies the DNA, giving you enough copies to study in detail.

Question 3

Why do we use E. coli for genetic experiments?

Accepted Answer

E. coli, a type of bacteria, is widely used in genetic experiments for several reasons. It's like the lab rat of microbiology. E. coli grows quickly, so you can see results in hours or days rather than weeks. It's also well-understood, with a wealth of scientific knowledge about its biology. Additionally, E. coli is relatively easy to manipulate genetically, making it an ideal host for experiments. Its simplicity and rapid growth allow scientists to efficiently study genetic changes and produce proteins.

Question 4

What is Golden Gate Assembly?

Accepted Answer

Golden Gate Assembly (GGA) is a technique used to piece together multiple DNA fragments in a precise and ordered manner. Imagine assembling a jigsaw puzzle where each piece has special sticky ends that fit together perfectly. In GGA, scientists use enzymes to cut and reassemble DNA fragments with complementary sticky ends, allowing multiple pieces to be joined in a single reaction. This method is like a sophisticated puzzle game where the pieces are designed to fit together in a specific order, enabling the construction of complex DNA sequences quickly and accurately.

Question 5

What is it like to work in the lab?

Accepted Answer

Working in a lab involves a mix of routine tasks, careful planning, and occasional surprises. It's like being a chef in a kitchen: you have recipes (protocols) to follow, precise measurements to make, and sometimes unexpected results. Lab work requires meticulous attention to detail, patience, and the ability to troubleshoot when things don't go as planned. There’s a lot of waiting involved, whether it’s for reactions to finish, bacteria to grow, or results to appear. The environment can be both collaborative and solitary, depending on the project.

Question 6

What are the Masters the player did in the game? What does one do there?

Accepted Answer

In the game, the player completed Masters degrees, which typically involve advanced study and research in a specific field. This experience includes attending lectures, reading scientific literature, and conducting experiments. The goal is to deepen knowledge and develop research skills. Each Master's degree would involve a significant project, requiring the student to design experiments, collect data, and analyze results, ultimately contributing new knowledge to their field.

Question 7

What parts of working in the lab were not shown in the game?

Accepted Answer

The game didn't show many aspects of real lab work, such as the extensive preparation before experiments, like calibrating instruments, preparing reagents, or maintaining sterile conditions. It also skipped the troubleshooting and repetition required when experiments don't work as expected. Additionally, data analysis, writing reports, and presenting findings, which are significant parts of lab work, were not depicted.

Question 8

How cutting-edge was the content of the game with respect to methods? Is it really that easy to put a gene into a new organism?

Accepted Answer

The content of the game was relatively cutting-edge, showcasing modern techniques like PCR and GGA. These methods are indeed used in real-world labs, but the game simplified the process. In reality, putting a gene into a new organism involves careful design, multiple verification steps, and often, trial and error. It's not as straightforward as the game makes it seem, but we hope to accurately represent the essence of the techniques .

Question 9

How important are citations in science?

Accepted Answer

Citations in science measure the impact and reliability of research. High citation scores boost a scientist's reputation, similar to awards for a filmmaker, making their work more respected. They also attract funding, as agencies look for impactful studies. Citations foster collaboration by connecting researchers and building on past work. In essence, citations enhance reputation, secure funding, and create a collaborative scientific community
