Chromosome ends are called
Open in App
Solution
The correct option is A Telomeres
1) Satellite chromosome is separated from the main body of the chromosome by a secondary constriction that serves as identifying markers.
2) A telomere is a region of repetitive nucleotide sequences at each end of a chromosome. They are the caps at the end of each strand of DNA that protect our chromosomes from deterioration or from fusion with neighboring chromosomes. They are like the plastic tips at the end of shoelaces. Without the coating, shoelaces become frayed. Similarly, without telomeres, DNA strands become damaged and our cells can't do their job.
3) The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids.
4) A kinetochore is a protein structure that forms on a chromatid during cell division and allows it to attach to a spindle fiber on a chromosome.
So, the correct answer is 'Telomeres'.
