How would overexposure to X-rays affect most animal cells?

• It would cause an increase in red blood cell production.

• It would increase cell specialization in organs.

• It would produce new nucleotides for DNA molecules.

• It would change the sequence of DNA nucleotides in affected cells.

Which is a step in the process of producing transgenic bacteria?

• A plasmid is used to replace a faulty gene in a human cell.

• A chain of bacterial amino acids is inserted into human DNA.

• A human gene is inserted into a bacterial plasmid.

• A mutation is produced in a bacterial cell.

This process gives us the ability to make infinite copies of DNA

• selective breeding

• inbreeding

• CRISPR

• polymerase chain reaction

This technology allows us to do cool things such as "reprogram" bacteria to make important medicines for us

• selective breeding

• cloning

• polyploidy

• recombinant DNA

Which is used to cut DNA molecules at specific points?

• gel electrophoresis

• PCR analysis

• a restriction enzyme

• recombinant DNA

What is gene editing?

• Produces genetically identical individuals.

• Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.

• Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.

• Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.

What is genetic modification (GM)?

• Produces genetically identical individuals.

• Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.

• Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.

• Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.
