Question

Choose the correct statement:

• A. Genes are located in the chromosomes
• B. The cell is located in the nucleus.
• C. Chromosomes are located in the nucleolus.
• D. Cell membrane surrounds the nucleus.

Answer 1

The correct option is A

Genes are located in the chromosomes

The correct option is A

Explanation of the correct option:

The unit of heredity found in chromosomes is called a gene.

The chromosomes have the following functions:

1. Chromosomes' primary job is to pass on genetic information from one generation to the next.
2. As a guiding force in the growth, reproduction, repair, and regeneration processes—all vital for survival—chromosomes play a significant role.
3. The DNA is shielded by chromosomes from tangling and damage.

Explanation of the incorrect option:

Option B:

1. When we look at a photograph of a cell, one of the parts that stand out the most is the nucleus.
2. The nucleus, located at the center of the cell, is home to all of the chromosomes, which are responsible for encoding the genetic material.
3. Therefore, protecting this component of the cell is very critical.

Option C:

1. Every cell in our body has a nucleus where chromosomes are housed.
2. Chromosomes are formed of DNA that is tightly wound around proteins. Our total number of chromosomal pairs is 23, and the only time they are clearly visible is during cell division.

Option D:

1. The cell's nucleus, which houses the chromosomes, is enclosed by the nuclear membrane, which is composed of two layers.
2. The chromosomes are kept apart from the cytoplasm and other components of the cell by the nuclear membrane.

Final Answer: The correct statement is genes are located in the chromosomes.
