Answer:
PCR is used to amplify the DNA.
Explanation:
PCR is acronym for polymerase Chain Reaction, a molecular biology procedure for amplifying segments of DNA, through the production multiple copies with the aid of the enzyme DNA polymerase under controlled factors. In PCR, thermal cycling or the continuous heating and cooling of the sample for DNA melting and replication is employed.
In this case, Once DNA is collected at a crime scene, it must be processed in the lab. But the DNA obtained was of limited quantity therefore it is advisable for the technician to amplify the DNA using PCR.
The recessive allele frequency for the population.
150 pigs have 300 alleles total
There exists 180 alleles for the recessive trait blue eyes.
Assign 'q' to the frequency of blue eye alleles
q = 180/300 = 0.6 Answer
I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
