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.
B). natural wind patterns, I took the Cumulative Exam.
The most effective way to keep dry land from becoming more arid is to use sustainable agricultural practices.
The right answer is "plant a tree belt"
The event of increasingly arid dry land or desertification is an event where the land becomes a very dry lack of water, vegetation, and also wild animals.
Answer:
B. kinetic energy
Explanation:
Kinetic energy is the energy of movement. Thermal energy is the energy of heat. The hotter a compound gets the more space the molecules have, this allows for increased movement.
A is the answer! Oh god I hate the mini characters limit
