Question
Which of the following structural feature is present at the end portion of a chromosome?
- Centromere
- Telomere
- Chromomere
- Chromonema
Hint:
Telomere
The correct answer is: Telomere
Telomeres are distinctive structures found at the ends of our chromosomes. They consist of the same short DNA sequence repeated over and over again.
Telomeres are located at the end of chromosomes, where they help protect against loss of DNA during replication. Telomeres can be restored by the enzyme telomerase, which extends telomeres length.

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.
