Answer: A gene that is hidden or not expressed.
Answer:
Partial nitrate reduction results in the formation of nitrite and water
Explanation:
the loss of electrons is known as oxidation!
Answer:
Lactic Acid Fermentation, which <em>produces the ATP molecule that animals and bacteria need for energy.</em> Lactic acid fermentation occurs when the ATP molecule is created without oxygen.
Alcohol/Ethanol Fermentation, which <em>causes certain sugars to be converted into alcohol and carbon dioxide</em> by bacteria on carbohydrate products/materials.
Answer:
The correct answer will be option-formation of heterochromatin
Explanation:
Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.
The methylation of DNA converts the cytosine residues to the 5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.
Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.
Thus, the formation of heterochromatin is the correct answer.
