2 new copies of each DNA molecule
1 new copy and one old copy of each DNA molecule
2 copies of each DNA molecule that are each half old and half new
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 funtional 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 molecue together. The DNA fragments of different sizes are spliced together.
A sample of DNA is added to a gel and exposed to a cureent. The DNA is attracted to the charge and different sized fragments of DNA are sperated.
The sample of DNA is repeadedly 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, 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 seperated 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
The nucleus of an egg and sperm are transfered into a donor egg
The chromosomes are removed from a 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 transfered 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 female 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.
