Which of the following statements is TRUE about reverse genetics? Reverse genetics analysis starts with mutants with altered phenotypes and identifies the genetic causes of the mutant phenotypes. O Reverse genetics can be performed by random mutagenesis but not targeted mutagenesis. Reverse genetics analysis starts with a known DNA sequence, mRNA, or protein. Reverse genetics analysis relies on controlled crosses between mutants with distinct phenotypes.
