What is the purpose of this virtual lab?

The Virtual Laboratory is an interactive environment for creating and conducting simulated experiments: a playground for experimentation. It consists of domain-dependent simulation programs, experimental units called objects that encompass data files, tools that operate on these objects.

Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms. (Click here for more on experimental design.) The fly glows only when a certain gene involved in circadian rhythms is activated.

Beside above, what is a virtual lab? The concept of a virtual laboratory in the physical sciences is one with many ramifications. In the most general terms, a virtual laboratory is a computer-based activity where students interact with an experimental apparatus or other activity via a computer interface.

Similarly, it is asked, what is the overall purpose of this virtual lab?

To familiarize students with the science and techonology used to identify types of DNA based on their DNA sequence.

How does a virtual lab work?

A virtual laboratory is an on-screen simulator or calculator that learners use to test ideas and observe results. They allow the learner to “tinker” with laboratory equipment that behaves in almost the same way as it would in a real environment. Learners perform a series of experiments that yield authentic results.

What are transgenic organisms used for in research?

Transgenic organisms are important research tools, and are often used when exploring a gene’s function. Transgenesis is also related to the medical practice of gene therapy, in which DNA is transferred into a patient’s cells to treat disease. Transgenic organisms are widespread in agriculture.

How much time does it take for the embryos to reach adulthood?

30 minutes

What does the period gene normally control for the fly?

Study shows that the clock gene period differentially regulates sleep and memory in Drosophila. Results indicate that the role of the clock gene period may be separable in specific aspects of sleep or memory. Overexpression of per also on poor medium resulted in life extension in female fruit flies.

What is the purpose of the pump to which the glass needle is attached?

What is the purpose of the pump to which the glass needle is attached? -Precisely regulates the amount of force ejected into and through tubing connected to the glass needle.

What is missing in the negative control tube?

The only thing missing in the negative control tube is DNA. The only thing present in the positive control tube that is not in the negative control tube is thepositive control DNA while the negative control tube contains only sterile deionized water.

What is the wire ring used for bacterial identification?

The wire ring is used to get a colony of bacteria off of the petri dish and place it in the.

What does highly variable mean?

What does “highly variable” mean? Its means that some of parts of a gene are extremely different among different species.

What are the basic steps for isolating and identifying bacterial DNA?

Basic Steps Prepare a sample from a patient and isolate whole bacterial DNA. Make many copies of the desired piece of DNA. Sequence the DNA. Analyze the sequence and identify the bacteria.

Why are highly conserved regions important in this lab?

Highly conserved regions are some parts of a gene that are extremely similar among different species. They are important because universal primers bind to them so that they can be used to copy DNA from a variety species of bacteria. Highly variable genes are genes that differ among different species.

Why are the digestive enzymes necessary for DNA extraction?

Enzymes are biological catalysts that play a role in the isolation of nucleic acids from tissue and microbial sample types. Today, enzymes are commonly provided in DNA isolation kits to enable cellular and organelle disruption and for the removal of contaminating proteins.

What’s a major assumption when drawing evolutionary relationships between organisms based on DNA sequences?

What’s a major assumption when drawing evolutionary relationships between organisms based on DNA sequences? The assumption is that; number of positions that differ in the nucleotides sequence is proportional to the time elapsed since the two-species formed their own lines of descent from a common predecessor.

How do you make a virtual lab?

Creating Virtual Lab Launch the New Virtual Lab wizard. Specify a virtual lab name and description. Select a host. Select a datastore. Set up a proxy appliance. Select networking mode. Create isolated networks. Specify network settings.
