Place where chromatin containing most of the cell's DNA is found.
What is the nucleus?
200
The shape of the DNA molecule.
What is twisted ladder or double helix?
200
The base that pairs with cytosine.
What is guanine?
200
Discovered double helical structure of DNA.
Who are Watson and Crick?
200
Sugar in DNA.
What is deoxyribose?
200
The chromatin forms these structures which replicate and separate during cell division. They are made of strands of DNA that are tightly would around proteins.
What are chromosomes?
300
Cytosine pairs with this nitrogen base.
What is guanine?
300
The base that pairs with adenine.
What is thymine?
300
Noticed that amount of cytosine present always equaled the amount of guanine present and that the amount of adenine present always equaled the amount of thymine present in a DNA sample.
Who is Chargaff?
300
Ladder rungs
What are nitrogen bases?
300
DNA codes for the production of these.
What are proteins?
400
Adenine pairs with this nitrogen base.
What is thymine?
400
The complementary DNA strand for the sequence of nitrogen bases ACGTAC
What is TGCATG?
400
Her photograph of DNA was used by Watson and Crick to conclude that the three dimensional shape of the molecule was a double helix.
Who was Rosalind Franklin?
400
Sides of the ladder.
What is sugar-phosphate backbone?
400
TAC GCG would produce this complementary strand of DNA.
What is ATG CGC?
500
The amount of adenine that Chargaff said would be present if there were 50 mg of thymine present.
What are 50 mg?
500
Complementary strand for AAA CCC.
What is TTT GGG?
500
Award won by Watson and Crick for their discovery of the structure of DNA.
What is the Nobel Prize?
500
RNA for short.
What is ribonucleic acid?
500
DNA is transcribed to this to begin the process of protein synthesis.
