Question 8

Question

Answer
  • 1869
  • 1896
  • 1986
  • 1698

Question 9

Question
Who discovered the components and arrangement of the nucleotides?
Answer
  • Phoebus Levene
  • Francis Crick
  • Sir William Henery Bragg
  • Erwin Chargaff

Question 10

Question
Who proved in 1943 that DNA does hold the genetic code?
Answer
  • Oswald Avery
  • Erwin Chargaff
  • Rosalind Franklin
  • Sir William Henry Bragg

Question 11

Question
What rules were created by Erwin Chargaff in the 1940's?
Answer
  • -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
  • -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
  • -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
  • -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

Question 12

Question
What was created in 1913-14 by Sir William Bragg and his son Sir William Lawrence?
Answer
  • X-ray crystallography
  • The first DNA structure (fake)
  • The first drawing of DNA
  • An artificial gene

Question 13

Question
In what time period did Rosalind Franklin and her partner Maurice Wilkins created a X-ray crystallograph of DNA, discovering the double helix structure?
Answer
  • early 1950's
  • late 1950's
  • early 1960's
  • late 1960's

Question 14

Question
Who refined the DNA structure and published it in 1951?
Answer
  • James Watson and Francis Crick
  • Rosalind Franklin and Maurice Wilkins
  • Maurice Wilkins and James Watson
  • Francis Crick and Rosalind Franklin

Question 15

Question
Who won the joint nobel prize in 1965?
Answer
  • Rosalind Franklin, James Watson, Francis Crick and Maurice Wilkins
  • Rosalind Franklin, James Watson and Maurice Wilkins
  • James Watson, Francis Crick and Maurice Wilkins
  • Rosalind Franklin, James Watson, Oswald Avery and Francis Crick

Question 16

Question
What year was the book, "The Double Helix" by James Watson, released?
Answer
  • 1968
  • 1869
  • 1986
  • 1896

Question 17

Question
What is the term used to describe the copying of DNA?
Answer
  • copying
  • doubling
  • replication
  • imprinting

Question 18

Question
What happens in the process of replication?
Answer
  • 1. the strands of the double helix separate from each other, much like a zip unzipping, leaving the bases exposed
  • 2. the exposed nucleotides pair with the exposed bases
  • 3. the sugar and phosphate molecules bond with neighbouring nucleotides, creating two identical DNA strands
  • 1. the DNA strand is split in half horizontally
  • 2. it is then separated in half, much like a zip unzipping, exposing the bases
  • 3. the bases then replicate and attach to the exposed bases
  • 4. the DNA strands then 'rezip', creating two identical DNA strands

Question 19

Question
Mitosis produces gametes that have half the number of chromosomes of the parent cell
Answer
  • True
  • False

Question 20

Question
Meiosis produces gametes that have half the number of chromosomes of the parent cell

Question 21

Question
What are network fibres?
Answer
  • the strands that pull the chromosomes to either side of the cell
  • underground wires that control the internet and phone lines
  • coils found inside a nucleus
  • another name for chromosome
