Answer:
The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis.
Explanation:
1. Separate white and red blood cells with a centrifuge.
2. Extract DNA nuclei from the white blood cells. ...
3. Cut DNA strand into fragments using a restriction enzyme.
4. Place fragments into one end of a bed of agarose gel with electrodes in it. 5. Use an electric current to sort the DNA segments by length.
Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
Answer: False.
Genetic drift is a stochastic process that occurs randomly through time. It refers to random fluctuations in allele frequencies due to chance events (small population size).
Explanation: Factors that can affect genetic diversity are Genetic drift, mutation, selection, migration, non-random mating and recombination.
Of these factors, forces that majorly control the fate of genetic variation in populations are genetic drift and natural selection.
Genetic drift refers to random fluctuations in allele frequencies due to chance events (small population size).
Natural selection involves environmental conditions acting on wild plant or animal populations or species. Most fit in a selection refers to genotype or phenotype with greater average reproductive output over it's lifespan than other genotypes or phenotypes.
Hello,
The answer should be "sound waves".
Reason:
If a gun go off the sound waves can go through anything to allow the person to hear for example: the sound wave can go through walls, water, and hard surface. It can also allow you to hear something but not see it therefore the answer is sound wave!
If you need anymore help feel free to ask me!
Hope this helps!
