Summary Introduction

To determine:

The effect of short telomeres in children in orphanages as compared to children having longer telomeres in foster homes.

Introduction:

The eukaryotic DNA(Deoxyribonucleic acid) has chromosomes highly coiled and packaged in a tiny nucleus. The chromosomes exhibit unipolar regions and they are known as “telomeres”.

Expert Solution & Answer
Check Mark

Explanation of Solution

The total cell division in a cell is directly proportional to the lengthof telomeres before the cell dies.

The longer telomeres mean that there will be more cell divisionsbefore the cell death. This will contribute to the longer life of the organism.

The shorter telomeres mean that there will be less cell division before the cell death. This indicates the premature death of an organism having shorter telomeres.

Conclusion

Therefore, the children living in orphanages having shorter telomeres will have a shorterlifespanthan the children having longer telomeres living in foster homes.
