Which of the following lists has the steps involved in the whole genome shotgun approach to Sequencing in the correct order? 1.
Paha777 [63]

Answer:

5,2,3,1 and 4.

Explanation:

Whole genome shotgun sequencing is the method in the genetics that are used to sequence the whole DNA fragments. Different DNA sequencing methods are chemical sequencing and Sanger sequencing.

The different steps that are involved in the whole genome shotgun sequencing are as follows. The DNA is isolated and  broken DNA with the help of the restriction enzymes. The genomic fragments are inserted into the cloning vector for its multiplication. These fragments are then transformed into the E.coli with the cloning vector. The sequence assembly is important step in the sequencing. Than the sequencing of the cloned fragments are done to find the sequence of the whole genome.

Thus, the correct sequence is 5,2,3,1 and 4.

One probable cause of age-related dna and cellular abnormalities is accidental injuries, such as pulled muscles. the release of
Leni [432]
The correct answer is the release of free radicals.  In accidental injuries such as a pulled muscle, there will be a subsequent inflammation and the inflammatory process involves the release of inflammatory mediators which then will increase the migration of inflammatory cells (i.e. neutrophils, lymphocytes) on the site of inflammation. This influx of inflammatory cells will produce a large amount of free radicals (i.e. hydrogen peroxide, superoxide ions) which then will damage DNA.

If an organism has 8 chromosomes in each of its sperm cells, how many chromosomes would you expect to find in its liver cells?
mafiozo [28]

Answer:

The correct answer would be - 16 chromosomes or 8 chromosome pairs per cell.

Explanation:

In the body of an organism, all the somatic cells have the same number of chromosomes irrespective of their location in the body which is 2n or diploid. Liver cells would also have 2n number of chromosomes. The diploid number of cells are produced by the mitosis type of cell division or by fusing the sex cell that are egg cells and sperm cells. These sex cells are haploid of n number of cells or haploid.

If a sex cell as given in question sperm cells have 8 chromosomes then the liver cell would be 2n because sex cells after forming a zygote develooped to all other somatic cells including liver cells.

Sex cell = n = 8 chromosomes

liver cell - 2n = 2×8 = 16 chromosomes.
