What is the role of insulin in the body?

• To signal the body to store sugar

• to signal the body to release sugar

• to signal the body to produce glucagon

• to signal the pancreas to start releasing enzymes

Bacteria will pick up stray bacteria and incorporate it into its genome through the process of:

• conjugation

• transformation

• translocation

• binary fission

Genes can be cut out of human or plant DNA & placed into bacteria in small rings of DNA called:

• mRNA

• SNP

• Plasmid

• Nucleotides

Besides heat shock what other technique can be used to transform bacteria?

• chromatography

• CaCl2 use

• PCR

• conjugation

The success of bacterial transformation is determined by:

• Transformation efficiency

• transformation success rate

• standard deviation

• gene expression ratio

What is SDS-Page?

• Type of gel used in protein electrophoresis

• soap solution that treats protein: breaks bond, gives - charge

• soap solution that treats protein: breaks bond, gives + charge

• a sub unit of a protein
