Explain what is meant by Chousekeeping gene and why the gene for enolase is not considered a housekeeping gene despite it being expressed in all tissues.
high spin whereas octahedral complexes can be either high or low spin, depending on the metal and/or ligand. What is the most likely explanation of this experimental result?
When a gas is collected by displacement of water,the gas often appears foggy as it is generated. what it means to say that a gas collected by this technique is saturated with water vapor.
