to their offspring on chromosomes.
 Walter Sutton
 Sex cells
 Diploid
EQ 7
What events occur during meiosis?
During meiosis, the chromosome pairs separate and are distributed to two different cells.
The resulting sex cells have only half as many chromosomes as the other cells in the organism.
 pg 172-173 the captions to the 7 steps of meiosis
EQ 8
What is the relationship between chromosomes and genes?
Chromosomes are made up of many genes joining together like beads on a string.
 Chromosomes
 Genes
 Alleles
EQ 9
What forms the genetic code?
The order of the nitrogen bases along a gene forms a genetic code that specifies what type of protein will be produced.
 DNA—double helix
o sugar, phosphates, nitrogen bases
 chromosomesDNAorder of bases amino acids proteins
EQ 10
How does a cell produce proteins?
During protein synthesis, the cell uses information from a gene on a chromosome to produce a specific protein.
 RNA
 Messenger RNA
 Transfer RNA
 pg 178-179 the captions for the 4 steps of protein synthesis
EQ 11
How can mutations affect an organism?
Mutations can cause a cell to produce an incorrect protein during protein synthesis. As a result, the organism’s trait, or
phenotype, may be different from what it normally would have been.
 Substitution
 Deletion
 Addition
 Effects of mutation
