The American Biologists who tested Watson and Crick's hypothesis for DNA replication were?
M. Meselson and F. W. Stahl
What is the purpose of incubation in DNA extraction?
This is to give a period of time for the DNA to grow by replication; this allows there to be enough of a sample of DNA to extract.
Is it DNA Copying or DNA Replication?
replication
During DNA replication what?
DNA replication produces two copies of the DNA.
Meselson and Stahl used what type of isotopes to determine mechanism by which DNA replicated?
nitrogen
What two scientists discovered the correct mechanism for DNA replication?
Meselson and Stahl
What was the name of the experiment that Meselson and Stahl worked on?
The experiment that supported the hypothesis that DNA replication was semiconservative was known as the Meselson-Stahl Experiment.
Which is the main enzyme used for the replication of DNA in ecoli?
DNA polymerase
Who performed the classic experiments that proved DNA was copied by semiconservative replication?
Watson and Crick mentioned it slightly in their paper but didn't propose a full method of replication. a number of different people collaborated to work out the full model of replication which is still no totaly finished, (few proteins left to find)
The American Biologists who tested Watson and Crick's hypothesis for DNA replication were?
M. Meselson and F. W. Stahl
Meselson and Stahl invented this new technique?
Meselson and Stahl conducted an experiment in 1958, and discovered that DNA replication was semiconservative. In semiconservative replication, when the double stranded DNA helix is replicated each of the two new double-stranded DNA helixes consisted of one strand from the original helix and one newly synthesized.
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
You briefly expose bacteria undergoing DNA replication to radioactively labeled nucleotides when you centrifuge the DNA isolated from the bacteria the DNA separates into two classes one class of la?
This looks like the Meselson Stahl experiement. Please see the link below.
DNA is copied during a process called?
Replication.
Does the process of DNA replication result in a copy of the original strand of DNA?
The process of DNA replication is semi-conservative. Which means, in the new (daughter) DNA double helices that are formed, one strand belongs to the parent strand (also referred to as the template strand) and the other is a newly synthesized strand. Subsequently, every new DNA molecule that is formed as a result of the replication process has one original parent strand and one newly synthesized complimentary strand.
What was Meselson and Stalh's confirmation of DNA's semiconservative sides of a DNA helix?
density gradient centrifugation
Why does your body undergo DNA replication?
So as to grow and sustain your life.
