The the nitrogenous bases of the DNA double helix are held together by hydrogen bonding. When a polar, protic organic solvent such as ethanol is added to solution, the H-bonding of the bases pairs break and reform with the ethanol in certain areas. The "stringy threads" that you are seeing are most likely single stranded DNA.
What else can I help you with?
How many gallons of gasoline that is eight percent ethanol must be added to two thousand gallons of gas with no ethanol to get a mix that is four percent ethanol?
400 gallons of gasoline with 8% ethanol must be added to the 2000 gallons of gas with no ethanol to achieve a mixture that is 4% ethanol. This is because in the final mixture, the quantity of ethanol is the average of the ethanol content in the two types of gasoline.
Which is a better solvent for boiling point elevation ethanol or water?
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
What effect does adding water have on the boiling point of ethanol?
Adding water to ethanol lowers its boiling point. This is because water forms an azeotrope with ethanol, which alters the vapor pressure of the mixture, resulting in a lower boiling point compared to pure ethanol.
What are the chemical steps for converting corn to ethanol?
Corn is first ground into a fine powder, which is then mixed with water and enzymes to break down the starch into smaller molecules. Yeast is then added to ferment the sugar into ethanol, carbon dioxide, and heat. The mixture is distilled to separate the ethanol from the other components, resulting in pure ethanol.
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.
Why methanol is added to ethanol?
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
Do Flying J stations add ethanol to their gasoline?
No, it comes in with the ethanol already added.
What are the solvent and solute in a containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
Does the pH of ethanol change if water is added?
Yes, adding water to ethanol will change its pH. Ethanol is a neutral compound with a pH of around 7. However, adding water will dilute the ethanol, potentially changing its pH depending on the amount of water added and the initial concentration of the ethanol solution.
Does the colour of potassium permanganate persist when it is added initialy to heated 3ml of ethanol?
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
What must be added to an aqueous solution of glucose to convert it into ethanol?
Yeast is added to the aqueous solution of glucose to convert it into ethanol through fermentation. Yeast enzymes break down glucose into ethanol and carbon dioxide.
Does potassium chloride dissolve in ethanol?
Yes, potassium chloride is soluble in ethanol. When added to ethanol, potassium chloride will dissolve to form a clear solution.
How many gallons of gasoline that is eight percent ethanol must be added to two thousand gallons of gas with no ethanol to get a mix that is four percent ethanol?
400 gallons of gasoline with 8% ethanol must be added to the 2000 gallons of gas with no ethanol to achieve a mixture that is 4% ethanol. This is because in the final mixture, the quantity of ethanol is the average of the ethanol content in the two types of gasoline.
What forms a white colour when ethanol and water are added?
precipitated
What is the name of the compound that is added to ethene to produce ethanol?
H2o
What compounds are produced when sodium nitrate is added to a mixture of water and ethanol?
When sodium nitrate is added to a mixture of water and ethanol, it dissociates into sodium ions and nitrate ions. No new compounds are formed.
