Answer:

The correct answer will be option D.

Explanation:

Genes are the coding sequence of the DNA which codes for specific proteins required for a function.

These genes are present physically as the segments on the DNA. These genes are important to an organism as they control a specific trait like the color of flowers and skin of a human.

The genes are located on a site called "locus' on pair of homologous chromosomes that is one on each chromatid. The number of genes varies from chromosomes that are genes can be present in a large number on a single chromosome.

These genes become functional only after they find a complementary pair on the chromosomes, the reason parents need to donate their genes during fertilization.

Thus, option D is the correct answer.

Answer:

d. Under normal circumstances, each chromosome contains precisely one gene.

Explanation:

The gene is a segment of a DNA molecule, responsible for genetically inherited traits. Each gene consists of a specific DNA sequence that contains a code (instructions) to produce a protein that performs a specific function in the body. Each human cell has about 25,000 genes.

The genes are located within the chromosomes. A chromosome can house thousands of genes, it is not normal for a chromosome to house a gene or a few units. Thus, if a cell contains 46 chromosomes, that cell has an incalculable number of genes.

dezoksy [38]

Answer:

<em>The shape of a cell can easily be seen through a light microscope.</em>

Explanation:

A microscope can be defined as a device which is used to visualize things which are otherwise not visible to the naked eye. The shape of a cell can be seen even through a light microscope. For example, an animal cell can be seen to have a round shape under the light microscope, a plant cell will be seen rectangular under the light microscope.

Other microscopes such as the electron microscope can even show the organelles present inside the cell.
