Answer:
46 chromosomes
Explanation:
Humans are diploid organisms i.e. they contain two sets of chromosomes (each set from each parent). Each set is 23 chromosomes, hence, two sets will be 23 pairs or 46 chromosomes. This means that each somatic/body cell will contain 46 individual chromosomes.
According to this question, DNA was extracted from a cheek cell. If one could magnify the extracted material, there would be 46 individual chromosomes from each of these cheek cells, considering that cheek cell is a somatic cell.

Answer:
Telomeres are the DNA sequences that are present at the end of chromosomes. The telomeres gets shorten after the DNA replication and are responsible for the ageing process.
The enzyme telomerase is responsible for the replication of telomeres. The telomerase enzyme lengthens the telomeres. This compensate for the the shortening of the chromosomes during each round of DNA replication of the humans.
