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:
See the answer below
Explanation:
Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:
<em>From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas. </em>
Answer:
When we observe the position of a star its position changes over the course of a year. It will return to the same position a year after the first measurement. This effectively proves that the Earth is in orbit.
Answer:
