DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.

So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)

The cessation of telomerase activity as we age limits the number of times a cell can replicate. current research on telomerases is particularly useful in the fight against cancer. This is because, Cancer cells employ a mechanism that activates telomerases, which leads to uncontrolled cellular division.

The body's stages of life are intimately correlated with telomerase activity. During the development of the embryo, the enzyme is active. High telomerase activity, which allows cells to divide endlessly, is a characteristic of cancer cells. In 85–95 percent of malignancies, telomerase is active (3,4).
