Expert Solution
Step 1

The deoxyribonucleic acid (DNA) is the hereditary material that transmits the genetic information from one generation to the next generation. It consists of two strands of polynucleotide chains that are wind around each other to form double helix. It is composed of nucleotides, sugar and phosphate.

Step 2

a.The telomers are the strings of short repeated DNA sequence that plays an important role in the protection of protein coding DNA in the chromosome. The DNA sequences that are present at the telomers of human chromosome are TTAAGGG.
