- AOswald Avery
- BErwin Chargaff
- CRosalind Franklin
- DSir William Henry Bragg
11What rules were created by Erwin Chargaff in the 1940's?
- A-nucleotides are not arranged in the same order in all species
-in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine.
-the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine - B-nucleotides are not arranged in the same order in all species
-in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine.
-each genetic code contains 'instructions' for a specific protein - C-each person has 46 chromosomes, in 23 pairs
-in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine.
-the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine - D-the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine
-DNA determines characteristics
-each genetic code contains 'instructions' for a specific protein
- A-nucleotides are not arranged in the same order in all species
12What was created in 1913-14 by Sir William Bragg and his son Sir William Lawrence?
- AX-ray crystallography
- BThe first DNA structure (fake)
- CThe first drawing of DNA
- DAn artificial gene
13In what time period did Rosalind Franklin and her partner Maurice Wilkins created a X-ray crystallograph of DNA, discovering the double helix structure?
- Aearly 1950's
- Blate 1950's
- Cearly 1960's

- B1869
- C1986
- D1896
17What is the term used to describe the copying of DNA?
- Acopying
- Bdoubling
- Creplication
- Dimprinting
18What happens in the process of replication?
- A1. the strands of the double helix separate from each other, much like a zip unzipping, leaving the bases exposed
- B2. the exposed nucleotides pair with the exposed bases
- C3. the sugar and phosphate molecules bond with neighbouring nucleotides, creating two identical DNA strands
- D1. the DNA strand is split in half horizontally
- E2. it is then separated in half, much like a zip unzipping, exposing the bases
- F3. the bases then replicate and attach to the exposed bases
- G4. the DNA strands then 'rezip', creating two identical DNA strands
