To tell your cells which proteins to make
To create DNA
To help your body decide which oxygen molecules are needed
To get rid of genetics
What organic molecules end in -ase
Sugars

the passing on of physical or mental characteristics genetically from one generation to another.
Genetics
Genes
Hereditary
DNA
Which of the following would NOT be an environmental influence on gene expression?
Temperature
Diet
Oxygen Levels
DNA
Why is crossing over so important to the survival of a species?
It allows there to be more genetic variation
It allows there to be less genetic variation
It allows there to be identical copies to be made
It allows for variation in mitosis
During which process does crossing over occur?
Mitosis
Meiosis
Fertilization
Asexual Reproduction
Which technique is used to separate and compare different DNA sequences based on size?
Gel Electrophoresis
Karyotyping
Recombinant DNA
Cloning
Which technique is used insert part of a DNA molecule from one organism into another organism?
Gel Electrophoresis
Karyotyping
Recombinant DNA
Cloning
Which technique is used to look at a picture of chromosomes?
Gel Electrophoresis
Karyotyping
Recombinant DNA
Cloning
Which technique is used to make a genetic copy of either a piece of DNA or an organism?
Gel Electrophoresis
Karyotyping
Recombinant DNA
Cloning
Why is recombinant DNA important?
It allows us to take gene from one organism and insert it into a bacterial plasmid so we can make a lot of that one gene
It allows us to take eggs from one organism and insert it into another organism to make a lot of that one type of organism
It allows us to determine if there are any genetic abnormalities in the growing fetus
It allows for undifferentiated cells to become anything that we need them to become
How is cloning of a mammal accomplished?
It allows us to take gene from one organism and insert it into a bacterial plasmid so we can make a lot of that one gene
It allows us to take an egg from one organism, take out the nucleus and replace it with the nucleus from a somatic cell and have an organism give birth to the new organism
It allows us to determine if there are any genetic abnormalities in the growing fetus
It allows for undifferentiated cells to become anything that we need them to become
What is a karyotype used for?
It allows us to take gene from one organism and insert it into a bacterial plasmid so we can make a lot of that one gene
It allows us to take an egg from one organism, take out the nucleus and replace it with the nucleus from a somatic cell and have an organism give birth to the new organism
It allows us to determine if there are any genetic abnormalities in the growing fetus
It allows for undifferentiated cells to become anything that we need them to become
Why are stem cells important?
It allows us to take gene from one organism and insert it into a bacterial plasmid so we can make a lot of that one gene
It allows us to take an egg from one organism, take out the nucleus and replace it with the nucleus from a somatic cell and have an organism give birth to the new organism
It allows us to determine if there are any genetic abnormalities in the growing fetus
It allows for undifferentiated cells to become anything that we need them to become
What are responsible for carrying genetic material and passing them off to the next generation?
Nucleotides
Amino Acids
DNA
Chromosomes
the process by which unspecialized or less-specialized cells acquire specialized structures and functions
Recombinant DNA
Gel Electrophoresis
Cloning
Differentiation
Why is DNA replication important?
It changes the DNA from single stranded to double stranded
whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Whenever a cell divides, the new daughter cell needs to have half the amount of the material from the original cell
It allows us to make the correct RNA sequence
Involves selecting parents that have characteristics of interest in the hope that their offspring inherit those desirable characteristics.
Asexual Reproduction
Sexual Reproduction
Selective Breeding
Cloning
Any random change in the DNA
Mutation
Recombinant DNA
Genetic Engineering
Cloning
If a mutation is going to be passed onto the next generation where does it need to be located?
The skin cell
The gametes
Stem Cells
The body cells
