Exam 6: DNA: The Molecule of Life

The signal transduction pathway allows ________.

Restriction enzymes were originally isolated from bacteria who used them to protect themselves from viruses.How might a restriction enzyme defeat a virus?

Entire genes may be deleted,inverted,replicated,or even translocated to another chromosome.Explain how each one could potentially result in cancer?

DNA profiling relies on an individual's ________,no two of which are the same between different people,except identical twins.

Genetically modified organisms that acquire genes from a different species are called ________ organisms.

Which enzyme is responsible for adding complementary DNA bases to an exposed DNA strand?

Three of the following statements are correct.Identify the statement that is not correct regarding genetically modified organisms.

What is the monomer of the DNA polymer?

What is different from one DNA nucleotide to the next?

Barr bodies are associated with ________.

A collection of cloned DNA fragments representing the organism's entire genome is called a ________.

Ribosomes are made out of which macromolecule?

Where does the bond form that binds one polynucleotide to the other polynucleotide?

When might a frameshift or nonsense mutation not result in a completely defective protein?

If the base sequence of template strand reads GCCATTAC,what is the base sequence of the mRNA?

Does the clone have a belly button?

The mighty chestnut tree once dominated many of our Appalachian forests,but was decimated by an exotic fungus in the first part of the 20th century.A few small groves of trees still remain in isolated pockets and living roots of some of the fallen ancient trees still try to send up new shoots.These shoots always die as soon as they are exposed to the fungus.How could chestnut trees be genetically modified to be resistant to the fungus and grow again?

What specific field of science is interested in examining the complete set of proteins encoded by a genome?

Which nucleic acid acts like an enzyme,stabilizing and orienting different molecules to facilitate the formation of bonds between them?

Occasionally the DNA may become damaged.Fortunately,several proofreading genes code for proteins that find and repair the damaged DNA.What might happen if one of these genes were damaged?
