The role of DNA in all cells is to produce molecules of RNA that are involved in protein synthesis. Through the proteins, all the metabolism of the cell is controlled. DNA is also used to synthesize new DNA for daughter cells.
A plant and animal cell is eukaryotic
a eukaryotic cell has a nucleus instead of floating DNA which a prokaryotic cell has
Answer:
RFLP analysis of genomic DNA is facilitated by Southern blot analysis. After electro-phoresis, DNA fragments in the gel are denatured by soaking in an alkali solution. This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix). A replica of the electrophoretic pattern of DNA fragments in the gel is made by transferring (blotting) them to a sheet of nitrocellulose or nylon membrane. This is done by placing the membrane on the gel after electro-phoresis and transferring DNA fragments to the membrane by capillary action or electro-transfer. DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.

Answer:
C; Oxygen concentration
Explanation:
Oxygen is product, not a reactant in photosynthesis. Light and carbon dioxide are reactants, and extreme temperatures can denature the plant.
