Correct answer: Telomere
Chromosomes contain DNA packed together with histone proteins. Each chromosome has cap like structures at their ends called the telomeres. These telomeres are protective in function and they become short with each cell division. The cells eventually age as the telomere shortens after each cell division. Every time the chromosomes replicate, it would be shortened by 250 bases. Telomeres prevent the loss of important segments of the DNA as they act as a cap at the ends of the chromosomes. At the end of each division, this protective cap is lost,
Answer:
economic viability, social equity and environmental protection
<u>Answer</u>:
If I were studying the causes of cancer, the topic which might interest me is "The topic of spindle-fibre structure.".
<u>Explanation</u>:
In cell division, the accurate segregation of chromosomes is coordinated with the complex structure of spindle fibre in cell. The mitiotic structure is consisted of two apparatus, one is centrosomes and the other is microtubules. Mitiotic spindle is formed during the polymerization process of the microtubules in centrosome. Any kind of disruption in the structure of the microtubules causes aberration in the spindle fibre structure and error in the number of chromosomes. This change is one of the major causes of developing cancer.
C. Inferential data analysis
This is because he fixes the population size and determines the parameter, the growth pattern, and then draws conclusions from it.
