phenotypesx
2. Select for and culture cells with beneficial characteristics
Can Mutated Genes be isolated? - Answers Yes
What is cDNA? - Answers Complementary DNA
DNA synthesized from an mRNA template using reverse transcriptase
, What is Reverse Transcriptase? - Answers Complex enzyme that allows retroviruses to make dsDNA
from RNA templates
