Answer:
d. to protect the end of a DNA molecule
Explanation:
Telomeres are like the protective shields of our cells' DNA.
Its name, of Greek origin, literally means "final part", and the telomeres are that: the ends of the chromosomes, something similar to the plastic tips of the shoelaces.
But they are very repetitive and non-coding parts of DNA: their main function is to protect the genetic material that carries the rest of the chromosome.
As our cells divide to multiply and to regenerate the tissues and organs of our body the telomere length is reduced, and so over time they become shorter.
When the telomeres finally remain so small that they can no longer protect the DNA, the cells stop reproducing: they reach a state of old age or old age.
Therefore, telomere length is considered a key "biomarker of aging" at the molecular level, although it is not the only one, and in recent years it has attracted the attention of numerous investigations.

Answer:
Limiting human use of nitrogen that is in the atmosphere.
Explanation:
DNA is able to control cellular activities most directly by regulating the process of Protein synthesis.
<span>The ecological condition of that patch is MICRO CLIMATE. Micro climate is the climate of a restricted area, which differs from the climate of the surrounding area. Local climates can vary greatly in a particular area depending on the prevailing factors such as wind, moisture, topography, vegetation, etc.</span><span />
