How is the Ames test used to quantitate mutagenic potential of chemical compounds? Select the TWO best answers. correct answers The Salmonella test strain used in the Ames test contains a mutation in the histidine biosynthetic pathway, which is used to identify compounds that induce back mutations to permit bacterial growth on histidine free plates. The chemical compound to be tested is added to a filter paper disk and placed on agar plates containing the tester Salmonella strain; potent muta...

Hemophilia Pedigree - Father has hemophilia, mother does not. What is the outcome for their kids? - His daughters would be carriers. This is x-link recessive. Autosomal: Dominant: - Autosomal: males and females equally affected. Dominant: non-carrier parents polymerase chain reaction (PCR) - The process of copying DNA in the lab. Uses Template DNA, Nucleotides (dNTPS), DNA Polymerase, and DNA primers. 3 Steps of PCR - 1. Denaturation: DNA is heated to 95C to separate it. 2. Annealing: re...

Why do helicase and gyrase need to work together? correct answers Helicase unwinds DNA and gyrase relieves the torsional strain. Match the name of the DNA repair mechanism with the correct description. Functions with DNA replication to remove incorrect nucleotides from the nascent strand. Requires an endonuclease to remove an abasic nucleotide before DNA Pol I can replace a portion of the strand. Is needed to repair chemical damage in DNA effecting more than one nucleotide, such as c...
