D. \[6.6\times {{10}^{9}}bp\]
E. 48502bp

Answer 1

Hint: Haploid is the consistency of a cell or organism that has a single set of chromosomes. There are haploid organisms which reproduce asexually. Diploid species are sexually reproductive (with two sets of chromosomes, one from each parent). In humans, there are only haploids in their eggs and sperm cells.

Complete Answer:
- Haploid refers to a cell or organism that has only one set of chromosomes. This is to be contrasted with diploid. A haploid cell has only one set of chromosomes, and most of the time it applies to so-called sex cells, either eggs or sperm.
- And these are critical transformation from a diploid cell to a haploid cell to enable normal reproduction to occur, so that when these two haploid cells come together with a single set of genetic information — single chromosomes — they can come together into a so-called zygote produced by the combination of an egg cell and a sperm cell, which then reconstitutes a diploid cell, which can then become a new individual.
- Haploid human genomes that are located in germ cells (egg and sperm gamete cells produced in the meiosis process of sexual reproduction prior to fertilisation) consist of three billion DNA base pairs, whereas diploid genomes (found in somatic cells) have twice the DNA content.
- DNA is a long polymer of deoxyribonucleotides, the length of which differs in different species. The total human DNA scale is \[6.6 \times {{10}^{9}}\] base pairs and this is a diploid in nature. Haploid means half the human DNA material, which is \[3.3 \times {{10}^{9}}\] base pairs.

Thus the correct answer is option (B) \[3.3 \times {{10}^{9}}bp\].

Note: While haploidy has not been reported in vertebrates, it occurs naturally in various eukaryotic organisms that differ from the diploid ancestor indicates that there is an inherent ability for an organism to recover haploidy and that haploidy can offer evolutionary benefits. Haploid embryonic stem cells have been experimentally developed from mice, rats, monkeys and humans.
