Using Molecular Techniques,researchers Have Knocked Out Both Copies of Gene

question 10

Multiple Choice

Using molecular techniques,researchers have knocked out both copies of gene "G" in a series of genetically identical mouse embryos.These mice develop normally,except for their forelimbs,which are missing several small bones.What can be concluded from the results of this experiment?

• A)Gene "G" encodes a protein that is a crucial component of the forelimbs' small bones in mice.
• B)Gene "G" encodes a protein that is normally only present in the forelimb cells of developing mice.
• C)Gene "G" is necessary for proper development of the forelimbs' small bones in mice.
• D)Gene "G" is normally only present in the forelimb cells of developing mice.
• E)Gene "G" is normally only transcribed in the forelimb cells of developing mice.
