Where is the DNA placed in gel electrophoresis apparatus?
Initially you inject it into the wells.
How does Polymerase Chain Reaction work?
Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.
What is the process used for DNA Sequencing?
There were initially two methods used for DNA sequencing, but today there are dozens. Genome sequencing is defined as any process that determines the order of nucleotides within an atom of DNA. It is almost always accomplished automatically in modern applications, using machines specifically designed for the job.
What is one thing that would need to be considered concerning the activity of this enzyme in PCR when the temperature is heated during each cycle to separate?
that the DNA polymerase could be denatured
What is the molecule transcribed from DNA called?
initially its hrRNA or pre-mRNA. (same thing different name). this then undergoes some modification like splicing, capping and polyadenalation to make mRNA which is then translated into protein.

What initially determines which DNA strand is the template strand and therefore in which direction RNA polymerase ii moves along the DNA?
the specific sequence of bases along the DNA strands
Would chromosomal DNA spool if it was heated to 100 degrees?
If heated to a hundred degrees, chromosomal DNA would denature. Meaning the it would come apart and the complementary DNA strands would separate. One way to get DNA to spool (around a glass rod for example) is to remove it from the cell and precipitate it in solution. This can be done with with help of sodium chloride and isoamyl alcohol.
When water is heated most of the energy that water initially absorbs is used to?
It breaks the hydrogen bonds between the water molecules
When liquid water is heated most of the energy that the water initially absorbs is used to raise the temperature of the water or break hydrogen bonds?
the .
Why when extracting DNA from onion cells why is the mixture heated to 60 degrees for 15 minutes?
so as to kill the cell
What is the final volume of a balloon that was initially 500.0 mL at 25C and was then heated to 50C?
After the law of Charles: 1 000 mL.
What causes two strands of DNA to split?
The answer depends on the circumstances! In a cell, during DNA replication or during translation, the two strands in a DNA molecule are separated by enzymes called topoisomerases and helicases. In a solution, the two strands of a DNA molecule can be separated by being heated. This is called DNA melting. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/DNA_melting
What happens to tomato when heated?
Initially the plants will wilt and then drop flowers and fruit.
What happens to DNA when heated to 95 degrees Celsius?
Like proteins, DNA and RNA will unravel and lose its shape because the chemical bonds holding it together will break apart.
