Explanation / Answer

Total number of the telomeres present in a cell = 194/ cell in human.

Explanation

Telomeres are present at each end of two identical chromatids in a chromosome.

Thus, 4 telomeres are present on each chromosome.

Therefore, 46 x 4 = 194 telomeres/ each diploid human cell.

b. Total number of the chromatids present per cell = 46 x 2 = 92.

Each cell contain 46 chromosomes and each chromosome contain two identical chromatids.

C. Total number of the chromosomes per cell = 46

Each diploid human cell contains two sets of chromosomes in which each contain 23 chromosomes. Therefore, 46 chromosomes are present per cell.
