DNA or protein?
The process by which harmless bacteria became disease causing bacteria was called this by Griffith
What is bacterial transformation?
This forms a base pair with thymine
What is adenine?
If a DNA strand has bases TACCG, it will produce a strand with these bases
What is ATGGC?
Griffith identified this in his series of experiments
In prokaryotes, DNA is organized in this way
What is circular?
When Griffith injected mice with the harmless, R-strain this happened to the mice.
What is they lived?
These scientists figured out that the shape of a DNA molecule is a double helix.
Who are Watson, Crick, Franklin and Wilkins?
In eukaryotes, DNA is found here
What is the nucleus?
Chargaff proved this
What is complementary base pairing?
In eukaryotes, DNA replication has multiple while prokaryotes only have two going in opposite directions
What are replication forks
Bacteriophages infect these
What are bacteria?
Chicken DNA contains 28%-adenine, 21% cytosine: the amount of guanine would be
What is 21%
This enzyme adds bases to a strand of DNA
What is DNA polymerase?
Mice that were given a mixture of heat-killed S strain and live R strain
Had this happen to them (outcome).
What is die?
In prokaryotes the number of chromosomes
What is a single chromosome
This part of the bacteriophage contains the genetic material
What is the capsid?
A nucleotide contains these 3 parts. They are:
What is deoxyribose, phosphate group and nitrogen base?
Chromatin contains proteins called these
What are histones?
These scientists conducted experiments using bacteriophages
Who are Hershey and Chase?
In prokaryotes, instead of histone proteins, these wrap around the DNA
What are Nucleoid-associated proteins
Hershey and Chase labeled the viral DNA with what radioactive compound
Name this compound and why they picked it/
What is phosphorus and because only DNA has phosphorus, protein does not?
Watson and Crick discovered the 2 strands in DNA are located like this
What are anti parallel?
These are responsible for keeping the two strands of DNA separated during replication
What are single-stranded binding proteins?
If protein had been the carrier of genetic information, scientists would have seen this radioisotope in the bacterial DNA after treating the bacteriophage with radioactive phosphorus or radioactive sulfur.
What is radioactive sulfur?
In prokaryotes, DNA is found here
What is the nucleoid?
