The given blank can be filled with forward genetics.
Forward genetic screen or forward genetics refers to a method used to determine a set of genes or genes accountable for a specific phenotype of a species. On the other hand, reverse genetics or reverse genetic screen evaluates the phenotype of a species following the disruption of a known gene.
The method of forward genetics was initially done by inducing mutants with radiation, by using naturally occurring mutations, insertional mutagenesis, or chemicals.
Answer:
The correct answer is- phosphorus and sulfur
Explanation:
Hershey and Chase used radioactive phosphorus and sulfur to label T2 bacteriophage. Then they infected E.coli with these bacteriophage labeled with radioactive phosphorus and sulfur.
After infection, they centrifuge the cell and found that radioactive phosphorus is present in the bottom and radioactive sulfur in supernatant . As sulfur is mostly the part of protein not DNA and is found in supernatant and phosphorus is mostly present in DNA not protein which was found in cell debris, therefore, it was proved that DNA is the genetic material.
Answer:
In glycolysis, NAD+ is reduced to form NADH.
Explanation:
NAD+ gains an hydrogen electron in the glycolysis pathway which translates to a reduction and not an oxidation.
There is also a subsequent oxidation that takes place in the electron transport chain system.
This facts makes NAD+ as being reduced to NADH in glycolysis as the right fans best option to choose from.
