Question
Which of the following statement is incorrect?
- Chromosome carries the genetic information
- Chromosomes protect DNA
- Human chromosomes are clearly visible only during cell division
- Human chromosomes in a cell are clearly visible at any point in time
Hint:
Human chromosomes in a cell are clearly visible at any point in time
The correct answer is: Human chromosomes in a cell are clearly visible at any point in time
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.

Which of the following is NOT an example of intra-genic gene interactions?
- Example of epistasis is fur color. The fur color of an animal depends on two genes (E and B). B gene is responsible for color while E gene determines the level of expression of the B gene.
