2 copies of each DNA molecule that are both old.
The process that produces a DNA fingerprint from a blood sample.
The process of cloning an individual.
The process of inserting gene from one organism into another.
The process of identifying a gene sequence.
Recessive alleles are weak alleles.
Recessive alleles make no functional gene product.
Recessive alleles are mutated forms of dominant alleles.
Recessive alleles are rare.
Ability to reproduce.
Ability to grow.
Ability to move.
Ability to respond to stimuli.
A sample of DNA is added to a gel which binds the molecule together. The DNA fragments of different sizes are spliced together.
A sample of DNA is added to a gel and exposed to a current. The DNA is attracted to the charge and different sized fragments of DNA are separated.
The sample of DNA is repeatedly heated and cooled in the presence of DNA polymerase and free nucleotides. Many copies of the fragments of DNA are produced.
A sample of DNA is added to a gel which holds the fragments in place. In this way, a fragment of different length can be distinguished.
A change in the DNA sequence.
A change in the amino acid sequence.
When a sample of DNA is cut up with restriction enzymes and separated by gel electrophoresis, the result is unique for each individual.
The impression left behind by a DNA sample is unique for each individual.
When a sample of DNA is compared to an individual's fingerprints, you can distinguish among individuals.
When a sample of DNA is amplified with PCR and mixed with DNA Polymerase, a unique set of fragments are produced for each individual.
A difference between populations.
A difference between individuals.
A difference in survival between individuals.
A difference in reproduction between individuals.
Fur color in a mammal.
Leg length in a bird.
Flower number in a plant.
Enzyme production in a fungus.
All of these.
None of these.
The nucleus of an egg and sperm are transferred into a donor egg.
The chromosomes are removed from an egg and replaced by the chromosomes from an adult cell.
The chromosomes from an egg are mixed with the chromosomes from an adult cell.
Selected chromosomes are transferred to the nucleus of an egg.
The nucleus of a fertilized egg is transferred to a donor egg.
Individuals have different traits.
Traits affect reproduction.
Traits are inherited.
All of these.
The technique requires that the egg develops in a female's uterus.
The technique leads to the production of a newborn infant animal.
The clone would be a younger identical twin to the donor of the DNA.
All of these.
Responding to stimuli.
The dung beetles store the balls of dung to feed on later.
The dung beetles lay eggs in the balls of dung and young will eat the dung when they hatch.
Only male dung beetles roll balls of dung.
Only female dung beetles roll balls of dung.
The dung beetles use the balls of dung to construct nests.
If dung beetles are laying eggs in the dung, the they will only roll balls of dung during daylight.
If dung beetles are laying eggs in the dung, then balls of dung placed in a container will hatch baby dung beetles.
If dung beetles are laying eggs in the dung, then most of the beetles rolling dung will be females.
If dung beetles are laying eggs in the dung then dung rolling will be most common during the breeding season.
