Why should a scientist use a plasmid with a GFP gene when inserting a new gene?
A) The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene
insertion worked.
B) The GFP gene will remove other genes, making it easier to see the effects of the new
gene.
C) The GFP gene is not well understood, so inserting it would be a valuable experiment all
on its own.
D) The GFP gene will stop the gene insertion from falling apart, making the results more
reliable.
Answer:
the answer is a
Explanation:
the GFP gene will make cells glow green in ultraviolet lights, confirming that the gene intersection worked.
A scientist use a plasmid with a GFP gene when inserting a new gene because it makes the phenotypes that is easily detectable. The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene insertion worked.
What is a GFP plasmid ?GFP plasmid is an engineered plasmid to be used in the biotechnology where the use of GFP will be in order to make up the genetic modified organisms.
The GFP plasmid will make up the multiple number of reporter genes that will help to detect the mutations and the inserted gene . The most notice GFP gene that will be detected is GFP that is green fluorescent protein and the ampicillin resistant gene that will make the gene look different from other types of genes present.
The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene insertion worked. This can be detected by the gel running when the screen is seen.

Hot glassware looks the same as room temperature glassware.
True
False
Hot glass look the same as cold glass. All chemicals in the lab are yo be considered dangerous. It's 300 to 500 degrees and doesn't look like anything special. Up to a point, yes. Below about 1200 degrees farenheit, glass doesn't change the way it looks.
Hot glassware does not look the same as room-temperature glassware due to thermal expansion. Therefore, the given statement is false.
When glass is heated, it undergoes thermal expansion. This expansion causes it to expand and change in shape. As a result, hot glassware may appear to be slightly distorted. They have a different shape compared to when it is at room temperature.
Hot glassware may emit a glow or radiate heat, indicating its elevated temperature. Therefore, there are visible differences between hot and room-temperature glassware. Thus, Hot glassware does not look the same as room-temperature glassware.
