Griffith’s Experiment
Name of the scientist that did this experiment
Frederick Griffith
Did they do just one experiment?
No, they did plenty
What does DNA stands for?
Deoxyribonucleic acid
What does RNA stands for?
Ribonucleic acid
Double-helix model
What did his experiment suggests
Bacteria are capable of transferring genetic information
What did they wanted to prove with their experiments?
That DNA is Genetic Material.
What is the role of DNA
Contains all genetic information on all living things and long-term storage information.
What is the other name of RNA synthesis?
Transcription
Why does DNA has a twisting shape?
Because of the reactions of its molecules and water. The hydrogen bonds in nitrogen bases are hydrophobic, so the repel water.
What animal did he use for experimenting?
What are the first names of both scientists?
Alfred Hershey and Martha Chase
What is the name of the molecules that made up DNA?
Which are the 4 nucleotides of RNA?
Adenine (A), cytosine (C), guanine (G), or uracil (U).
Which parts of the cell contain water-based liquids?
Cytoplasm and cytosol
Process by which bacteria transfers genetic information
Transformation
With which two things/tissues did they do the experiments?
Proteins and DNA
Mention the 4 nucleotides that made up DNA
Adenine (A), thymine (T), guanine (G) and cytosine (C).
What is the name of the enzyme that holds RNA's nucleotides?
Polymerase
What shape did DNA had the first time it was seen?
X shape
In what year did he started experimenting about this?
1928
How did they differ a substance that is genetic material from another that's not?
They put a radioactive protein and DNA into a bacteria and with the DNA the bacteria got infected and with the Proteins not.
Each nucleotide contains 2 groups and 1 base, of what are they made up?
A phosphate group, a sugar group and a nitrogen base.
What determines RNA's sequence?
A complementary base-pairing of the RNA nucleotides to a single-stranded DNA template.
Why did they thought that DNA had a "X" shape?
They were watching it from above so they only saw X's.
