Cold isopropanol is used for DNA precipitation because it causes the DNA to become more insoluble and allows for better precipitation of the DNA from solution. Lower temperatures help the DNA strands stick together and form a visible precipitate, making it easier to isolate the DNA from the solution.

Is nitrogen hot or cold?
Nitrogen is a gas at room temperature and pressure, so it doesn't have a specific temperature. When liquid nitrogen is in contact with objects at room temperature, it can appear very cold because of its extremely low temperature of around -196 degrees Celsius.
What is the calculations for a cold room?
To calculate the cooling load for a cold room, you need to consider factors such as the insulation of the room, temperature difference between the desired inside temperature and the outside temperature, heat gain from lighting and equipment, and air infiltration. This information is then used to determine the required refrigeration capacity for the cold room system. Consulting with a professional HVAC engineer is recommended for accurate calculations.
Does hot or cold water reach room temp first?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
What is one reason that room temperature water boils faster than cold water?
Room temperature water boils faster than cold water because it is closer to the boiling point, requiring less energy to reach that point. Cold water must first be heated to room temperature before it can reach the boiling point, delaying the process.
Why are droughts cold?
Droughts are cold because air is a natural cool temperature.. in your house your temperature is normally a warm or average temperature... your body..being warm as your core body temperature, you feels droughts because the air is pushed through under your door cooling the air inside the room. It's only cold because the room is normally, nevertheless warm. Another example - if your room was freezing cold you would most probably not even feel the drought only because the room if more colder then the air behind the door. - droughts are a natural cold substance and humans core temperature does not match up to it as same with the temperature of the room. (This is my estimated answer..may need summering up)
Does chocolate taste better cold or room temperature?
It tastes better in a cold temperature.
How do you use temperature in a sentence?
The temperature suddenly dropped and the room got cold, very cold.
Why does cold water revert to room temperature?
When cold water is exposed to a warmer environment, it absorbs thermal energy from the surroundings, causing its temperature to increase until it reaches equilibrium with the room temperature. The heat transfer occurs due to the difference in temperature between the cold water and the room, with the water losing heat until it matches the ambient temperature.
What is self annealing?
Its when a metal can recrystallize and have grain growth at room temperature, and so can be cold worked but not be strain hardened at the same time- its rather useful.
How cold is water with a betta fish in it if it is just sitting at room temperature no heaters or anything?
Room temperature.
Is nitrogen cold or hot at room temperature?
Anything at room temperature is regarded neither cold nor hot. <><><><><> If the question meant "Is nitrogen solid, liquid, or gaseous at room temperature?", then the answer is gaseous.
Is nitrogen hot or cold?
Nitrogen is a gas at room temperature and pressure, so it doesn't have a specific temperature. When liquid nitrogen is in contact with objects at room temperature, it can appear very cold because of its extremely low temperature of around -196 degrees Celsius.
Is it better to blow cold air in or hot air out for effective temperature control in a room?
Blowing cold air in is better for effective temperature control in a room.
What is light that is produced at room temperature?
Cold light
How can you bring cold air into a very hot tanning salon so it is room temperature?

Is carbon dioxide hot or cold?
Carbon dioxide is a gas at room temperature, so it does not have a specific hot or cold temperature. Its temperature depends on the environment it is in.
