Explanation:

Shotgun sequencing is a method used to determine the nucleotide sequence of entire chromosomes/genomes. This sequencing method consists of obtaining random DNA fragments which are subsequently classified by bioinformatic tools that ordering them according to overlapping sequences called contigs. In the whole-genome shotgun (WGS) technique, the entire genome of an organism is sequenced, being the critical factor the depth of sequencing, which refers to the quality of the sequencing reads (e.g., a depth of 20X indicates that the genome is sequenced 20 times by a sequencing machine). For the human genome, WGS became available after the completion of the Human Genome Project (HGP), which enabled the generation of a reference sequence for the whole human genome. The steps of the WGS technique are the following:

1. Preparation of isolated chromosomes

2. The DNA is sheared into small fragments

3. The DNA fragments of about 1 kilobase (1000 base pairs) are incorporated into plasmids which are cloned to render pure samples of each DNA fragment

4. The plasmid clones are sequenced by sequencing machines

5. Bioinformatic tools finally are used to link DNA fragments by their overlapping ends

Why do we want to turn genes off or on?
Dmitrij [34]

The process of turning off and on of genes is known as gene regulation.

Explanation:

When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.

The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.

Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.

<span>The answer would be: a. inflammation is accompanied by an increase in peristaltic movements of his small intestine.

The pathogen will attract the white blood cells that will induce inflammation in the intestine. Inflammation of the intestine will cause increased permeability and increased bowel movement, makes the food transit time reduced and lead to diarrhoea. This mechanism is beneficial since it can help the intestine to "flush out" pathogen of toxins that induce the inflammation.</span>
