D. 124 DNA molecules
E. 248 telomeres
F. 124 DNA molecules

This is just some review homework (stuff I should know fromprevious classes, but I'd like to have reaffirmation that I'm notmaking stuff up out of my head and that I am actually rememberingthe correct amounts).

Explanation / Answer

Basically, I think you did correctly for all the answer. I don't think you have problem in mitosis problem as it is thesimplest case of question. A general rule is to remember is after meiosis I, the number ofchromosome become halved. Also, 1 DNA molecule contains 2 telomere. Hope this helps!
