What else can I help you with?
Scientist wants to insert a new gene into a bacterium. What is the first step in this process?
Cutting the gene out of DNA with enzymes - gradpoint
A scientist is trying to find a method to artificially produce a protein that is found in a chicken's liver. Once the scientist has isolated the gene responsible for the protein how can he or she make?
Insert the gene into bacteria. -Apex
When was pantothenic acid isolated?
It was first isolated in the liver in 1933.
What is Bt gene?
A gene isolated from a bacterium that produces a crystalline protein that when eaten by insects shreds their insides kills them. Acts as an effective biological alternative to pesticide for this reason.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
How do you isolate the gene in genetic engineering?
You isolate the gene in genetic engineering by first locating the gene you wish to be isolated. Then you use a restrictive enzyme to isolate it, and lastly take the gene out
How is evolution different in small populations?
isolated gene pools
What happens to any population when its small and isolated from gene flow?
Mutations
What does the symbol for the gene HD mean?
A single abnormal gene produces HD. In 1993, scientists finally isolated the HD (Huntington's Chorea) gene on chromosome 4.
A single isolated gene can be cloned MOST rapidly using genetically engineered?
bacteria

Cutting the gene out of DNA with enzymes - gradpoint
When was cholera first isolated?
Robert Koch was the person who first isolated cholera in 1883
What year was helium isolated?
It was first isolated in 1895 by William Ramsay.

In order for a bacterium to produce a eukaryotic protein what must first be isolated from the cell prior to cloning?
The cDNA (complementary DNA) encoding the eukaryotic protein must first be isolated from the cell prior to cloning. This involves reverse transcription of the messenger RNA (mRNA) and subsequent amplification to obtain the gene of interest for cloning into a bacterial expression vector.
What was the first virus to be isolated?
The first virus to be isolated and identified was the tobacco mosaic virus in 1892 by Russian scientist Dmitri Ivanovsky.
When was pantothenic acid isolated?
It was first isolated in the liver in 1933.
