... so that the cell is regulated. If all the genes were swithced on at one time the cell would go haywire and produce excess amounts of proteins not necessarily needed, and possible causing problems within the cell.

Cells must regulate gene expression so that genes will only be expressed when the proteins are needed?
The answer is encoded in your question.
When do cells control gene expression?
By limiting the length of time mRNA is available for translation. Source: Biology textbook
In the binding of RNA polymerase to a gene requires the aid of a transcription factor?
Like prokaryotes, eukaryotes must regulate gene expression. This is accomplished primarily by controlling when RNA polymerase binds to the beginning of a gene. This binding cannot take place in eukaryotes without the aid of transcription factor.
Manipulating the arrangement of DNA that makes up a gene is called?
Genetic engineering
List three types of body cells that must be replaced frequently?
Muscle cells,Skin cells, and white blood cells.

What genetic disorder causes a defective gene that makes proteins necessary to pump chloride in and out of cells?
Cystic Fibrosis
What must happen inside the cell for gene therapy treatment to be successful?
n the simplest forms of gene therapy, the DNA must be integrated into the genome of the cell (it must become part of the regular DNA that is in the cell) so that it is replicated when the cell divides and passed on to all the daughter cells. In addition, it has to integrate into a part of the DNA so that it can be expressed so that it can make the missing protein. There are other forms of gene therapy for particular diseases where temporary expression therapeutic gene is all that is needed. For example, to make a tumor susceptible to certain drugs to cure the patient. In this case, integration is not needed and the DNA needs only to get into the nucleus so the gene can be expressed.
In gene therapy how are the genes inserted?
Working genes have been inserted into defective cells during gene therapy by first isolating a copy of the gene. Next, the working genes are planted onto a cold virus and as the cold virus infects cells, it also begins producing functional CF protein. Since the cells are "cured", they are able to transport chloride ions across their plasma membranes.
What does Gene therapy research use to alter defective hereditary material?
Researchers replace a mutated gene with a healthy copy of the gene. The healthy gene must first attach to a chromosome within a patient's cells. Then the gene needs to make the correct type and amount of protein. These techniques are still experimental at this time.

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testis For this to happen there must be direct communication?
integrins
What describes the process of DNA Recombinant?
There are steps you must follow in the making of recombinant DNA such as use crosses to identify donor, clone gene in bacterium, characterize the gene, modify the gene, and reintroduce the gene into donor cells.
How does in vitro technology work?
In vitro therapy involves injecting the new gene directly into the target tissue where the individual cells must pick it up.
Why are regulatory genes so important?
Genes are segments of DNA that code for proteins. Genes are either regulated by being switched "off" or "on" - meaning they are not currently making their proteins OR they are currently making their proteins. It is to a cell's advantage to not make proteins from genes when they are not needed to conserve energy and building materials. Hope this helps - Coach H
The process of attempting to cure genetic disorders by placing copies of healthy genes into cells that lack them is known as?
The process of replacing a defective gene with a healthy gene is called gene therapy. Gene therapy is done by cutting genes from the DNA of healthy cells and inserting them into the DNA of defective cells and tissues.
