Answer:
Although it is controversial topic, it is not a recommended practice among socienty to cultivate BT corn when alternative methods of increasing plant yield are already available. On the other hand, scientists are encouraging more research on genetically modified (GM) solutions with lesser/reduced impact on ecosystem.
Explanation:
Although, cultivating BT corn helps improving the yield, reduce insecticides usage, and enhance the grain quality, it has been extensively debated to reduce this practice globally. This is because of severals reasons. At first, cultivation of BT corn affects non-target organisms that interact with the plant for symbiotic or neutral reasons including pollination. Due to genetic modificaitons, BT corn produce BT-proteins that kills the non-target organism. Secondly, it increases the insect resistance and those insects which survives even after chewing plant tissues of BT-corn, they are found to have resistance against several toxins at high doses. Once these chemicals enters the food chain, they could be extremely toxic to other naturally growing organisms.
Prince Charles stated that use of GM plants is disaster and should be banned immediately. Likewise, he said that it is also impacting the climate change. On the other hand, Prof. Smith showed a contradictory opinion and said that the views of Prince Charles are saddening. He is seeing the one sided picture only. He should ask for extensive research rather discouraging this aspect of modern science.
In my opinion, I would also say that the technology should be improved and make more eco-friendly rather than complete abolishing especially when the apparent benefits are greater than the harmful effects.
First of all just to point out that this isn't a biology question :)
Ok so to solve this you have to expand to spare first
8k(4k^2-12k+9)
Then multiply the 8k
32k^3-96k^2+72k is the answer
Answer:
b. A second marker in the knock-out cassette, that if inserted into the genome results in cell death when plated on selective media.
Explanation:
General recombination, also known as homologous recombination, refers to the naturally occurring process of exchange of genetic material between pairs of homologous DNA sequences. This process (homologous recombination) can be exploited by genetic engineering to insert DNA segments of interest at target genes. Moreover, a cassette is a mobile DNA segment containing almost a gene and a recombination site, which is integrated into the <em>locus</em>/<em>loci</em> of interest by homologous recombination. A cassette may contain a DNA segment called 'negative marker' which prevents growth under particular conditions, while a positive marker permits growth under certain conditions. In consequence, a second marker consisting of a drug cassette may be used as a negative marker in order to evidence its insertion by inducing cell death when they are plated in selective conditions.
Answer:
i dont know actually but i belive in you . rremeber that you atre great and beutiful. i love you
Explanation:
I believe the answer would be B where the condensed chromosomes line up at the equator of the cell.
