Answer:
Telomeres
Explanation:
Telomeres are present at the ends of chromosomes and prevent the lose of genes. They shorten as a person ages. Thus lengthening them may slow down age related problem.
If telomeres could be lengthened, the age-related problems could be slowed.
• The end of a chromosome is known as a telomere it is formed of repetitive sequences of non-coding DNA, which protect the chromosome from destruction.
• With each cell division, shortening of telomere takes place. Eventually, with too much shortening of telomere the cell fails to divide any further.
• It is seen that with age shortening of telomere takes place.
• The continuous shortening of telomere results in apoptosis, senescence, thus, influencing the lifespan and health of a person.
• Shorter telomeres have been related to poor survival and increased incidence of diseases.
• It is believed that if the lengths of the telomeres can be increased than the age-related issues could become slow.
• However, the shortening of telomere can be increased or decreased by some of the lifestyle factors.
• Activities and better choice of diet possesses great tendency to diminish the rate of telomere shortening.
Thus, the given blank can be filled with telomeres.
