Answer:
Inversion
Explanation:
This type of mutation is not as lethal on addition of deletion mutations. This is because it does not cause a frame-shift mutation. Inversion only reverses the order of nucleotides in a section of a DNA strand and the genes in this regions may produce defective proteins.
Purpose:Extraction and successful PCR amplification of DNA from humanremains in historical and forensic cases have great importance. The purpose of this study is to demonstrate the efficiency of a method of DNA extraction and PCR amplification of embalmed dried human cadaveric skeletal fragments and teeth specimens from Sokoto, Northwestern Nigeria.
Materials and Methods: The efficiency of a method of DNA extraction and PCR amplification was tested on thirteen (13) embalmed dried human cadaveric skeletal fragments and nine (9) teeth specimens from Sokoto, Northwestern Nigeria were used in the study.
Results: Of the 13 embalmed dried human cadaveric skeletal fragments, 12 (92.3%) samples amplified with apparent bands. For the 9 embalmed dried human teeth specimens, 7 (78%) samples amplified with apparent bands.
<span>Conclusion: The study has shown that our method of DNA extraction and PCR amplification was efficient on embalmed dried human cadaveric skeletal fragments and teeth specimens, from Sokoto, Northwestern Nigeria.</span>
Answer:
carbon dioxide
Explanation:
Hope this helps! :)
because with to much of it in the atmosphere it would become harder for us to breath and the affects of oxygen deficiency are bad.
Answer: There will be one homozygous straight wing, two heterozygous straight wings, and one homozygous curly wing.
Explanation: A true breeding pair means that both parents are heterozygous (Ww). Set up a Punnett square with two Ww parents. The offspring will be 1 WW (homozygous straight), 2 Ww (heterozygous straight), and 1 ww (homozygous curly).
Answer:
In natural selection, genetic mutations that are beneficial to an individual's survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce. ... Those differences are at least in part determined by their genes.
