Answer:
dense regular connective tissue
The first answer is c.every type . I think the following one is d
<span>as DNA is replicated, the DNA base pair that will bond to cytosine is : Guanine
Guanine is one of the main nucleobases found in DNA, which is belonged to the double-ringed class of molecules called purines consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds.I hope that my answer is helpful! Let me know if you need something more :)</span>

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.
