The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".
<u>Option: C</u>
<u>Explanation:</u>
With the development of the PCR technique, DNA profiling has made enormous progress both in its distinguishing capacity and in its ability to survive information from very limited or damaged beginning samples. The PCR cycle mimics the biochemical mechanism of DNA replication yet restricts it to fragments of concern unique to DNA.
In the PCR method, the specimen of DNA is denatured by heating into separate polynucleotide strands. Two primers of DNA oligonucleotides are used for hybridization on opposite DNA strands to two matching nearby sites. Thus two new copies of the interest sequences are produced. Quantitative PCR methods allow accurate, high and automated calculations of the throughput.
Answer:
the one at the top is formed by meiosis
the one on the left and right side if four chromosome
the middle one is eight chromosomes
the last one is mitosis
Explanation:
The statement 'the yeast cell mutated the gene to make it compatible' correctly explains this occurrence.
- Gene transference is a type of methodology by which a specific gene is transferred between different organisms.
- Gene transference involves genetic engineering techniques such as the use of endonuclease restriction enzymes.
- In this case, the human gene was transferred to the yeast.
In conclusion, the statement 'the yeast cell mutated the gene to make it compatible' correctly explains this occurrence.
