5 True/False Questions

1. base pairing rules → gene that can transpose themselves to new positions within the genome of a single cell; used for genetic engineering

   True        False

2. enzymes → ________________ maximize the odds that the new DNA strand is an exact copy of the original

   True        False

3. Lac Operon → sequence of a gene's DNA that codes for a protein

   True        False

4. transcription → start codon positions in P site, tRNA brings in second amino acid and a peptide bond forms (assembling proteins)

   True        False

5. pyrimidines → A and G: purines or pyrimidines?

   True        False
