GENETICS Worksheet

occurs when certain genetic mutations in a cell can result in uncontrolled cell division. Cancer can be caused either by heredity or environmental factors like radiation, chemicals or virus.
is the passing of genetic information from one generation to the next through reproduction.
. The hereditary information----is organized in the form of genes located in the-------of each cell.
Identical Cells, 1 Parent, Little Genetic Variation
Not Identical Cells 2 Parents Much Genetic Variation
Identical genetic copies are known as
is a double stranded helix polymer of nucleotides that contains the genetic code of the individual.
is the basic unit of DNA which is made of a Phosphate, a Sugar and a Base.
is a single stranded polymer that is produced by DNA.
any alteration of the DNA sequence which changes the normal message carried by the gene.
DNA uses RNA to make a protein. This is termed
ONE BASE IS PUT IN THE PLACE OF ANOTHER
A BASE IS LEFT OUT
A BASE IS ADDED
BASES ARE SWITCHED
An organism's environment can affect the way that some genes are expressed.
technology that humans use to alter the genetic instructions in organisms
cutting DNA and placing it into another organism
an enzyme that cuts DNA in specific places and is an essential tool in gene splicing as well as in Gel-electro phoresis
just like a bar code the more common the bars the more common heritage or ancestry
a process of picking parents with favorable traits to produce those traits in the offspring.
a group of closely related organisms that share certain characteristics and can produce offspring capable of reproduction.
