Transfer of DNA into cells is called what?
Transcription
What are the factors that can affect the transfection efficiency and how?
Factors that can affect transfection efficiency include the type of transfection reagent used, the concentration of DNA or RNA being transfected, the cell type being transfected, and the health and confluency of the cells. The choice of transfection method, such as chemical or viral transfection, can also impact efficiency. The presence of serum or antibiotics in the culture medium, as well as the timing of transfection, can also influence transfection efficiency.
How is the incorporation and expression of a plasmid achieved within eukaryotic cells?
Incorporation and expression of a plasmid in eukaryotic cells is typically achieved through a process called transfection. This involves introducing the plasmid DNA into the cells using methods such as electroporation or lipid-mediated transfection. Once inside the cell, the plasmid can be expressed by the cell's machinery to produce the desired protein or gene product.
What is the significance of monitoring cell confluency in a cell confluency chart for cell culture experiments?
Monitoring cell confluency in a cell confluency chart is important in cell culture experiments because it helps researchers track the growth and health of cells. By measuring the percentage of surface area covered by cells, scientists can determine when cells are ready for experiments or when they need to be passaged. This information ensures that experiments are conducted with cells in the optimal state for accurate and reliable results.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.

What is transient transfection?
Transient transfection is a method used to introduce foreign DNA into cells for a temporary period, typically a few days. This allows researchers to study gene expression, protein function, and other cellular processes without integrating the foreign DNA into the host cell genome. Transient transfection is often used in laboratory settings for quick and reversible manipulation of gene expression.
What practical use can the transfection process be used for?
The transfection process can be used practically in procedures where foreign DNA needs to be introduced into bacteria or mammalian cells. It can be used in investigating gene function and modulation of the gene expression, contributing to cellular research, drug discovery, and target validation.
What are the easiest cells to grow in a lab?
epithelial cell
Why are onions and humans used as the source of cells?
Onions and humans are commonly used as sources of cells for study and research because they are readily available, have easily observable cells, and can be easily manipulated in laboratory settings. Additionally, their cells have distinct characteristics that make them useful for different types of experiments and investigations.

Which healthy cells in the body are commonly affected by antineoplastic agents?
Cancer cells are commonly affected by antieoplastic agents.
What is a sucrose solution and how is it commonly used in scientific experiments or research?
A sucrose solution is a liquid mixture made by dissolving sucrose (table sugar) in water. It is commonly used in scientific experiments or research as a medium for preserving biological samples, such as cells or tissues, by maintaining their structure and preventing damage during storage or transportation. Sucrose solutions are also used in density gradient centrifugation to separate and purify different components of a sample based on their density.
