Question
Chapter 11, Problem 31A
Summary Introduction
To hypothesize:
The need for telomeres.
Introduction:
Chromosomes are the structures that contain the genetic material that are passed from generation to generation of cells. A chromosome consist of two identical sister chromatids. The protective ends of the chromosomes are called telomeres. They are made of DNA associated with proteins.
Expert Solution & Answer

Answer to Problem 31A
- Telomeres are needed to protect the ends of chromosomes during cell division.
- They protect important genes at the end of chromosomes.
- They help in replication process.
- They are involved in aging and cancer.
Explanation of Solution
- Chromosomes have protective caps called telomeres that consist of DNA associated with proteins. The cap serves as a protective function for the structure of the chromosome. Without these DNA strands get damaged and cells don’t function properly.
- They protect the vital information in the DNA.
- Telomeres help in replication of DNA. They protect the vital genes from being deleted as DNA strands shorten during replication.
- Telomeres get shorter with age. So missing telomeres is a sign of aging and sometimes indicate cancer.
