Question

In which of the following haploid cells, the genome in human beings is present?
A. Sperm
B. Somatic cell
C. Mating RBC
D. Primary spermatocyte

Answer 1

Hint: The full complement of DNA from a cell is called its genome. For prokaryotes, the genome is composed of a single, double-stranded DNA molecule, in the shape of a loop or circle. A nucleoid is called the area in the cell that contains this genetic material. The genome contains multiple double-stranded, linear DNA molecules in eukaryotes that are bound to proteins to form complexes known as chromosomes.

Complete answer:
In the nuclei of cells, each eukaryotic species has a distinctive number of chromosomes. There are 46 chromosomes present in human body cells (somatic cells). There are two paired sets of chromosomes in a somatic cell, an arrangement defined as a diploid. The letter ‘n’ is used to denote a single chromosome set; 2n is therefore designated as a diploid organism. Gametes, or sex cells, are human cells containing one set of 23 chromosomes. These eggs and sperms are referred to as n or haploid.
The sperm is the male haploid gamete, formed by spermatogenesis. A single set of 23 chromosomes is present in the sperm. These are the genes that the father contributes to the zygote. The other set of 23 chromosomes is obtained from the egg cell. The gametes combine to create a diploid zygote. Diploids are the somatic cells and the main spermatocytes. There is no nucleus in mature RBCs and hence, no genes are present.

So, the correct answer is option (A).

Note:
From 1990 to 2003, the Human Genome Project (HGP) provided scientists with basic knowledge about the sequences of three billion base pairs in DNA. The Human Genome Project (HGP) was a major scientific research project to establish the basic pairs that make up human DNA and to classify and map both physically and functionally all the genes of the human genome.
