Human cells normally have 46 chromosomes. For eachof the following stages, state the number of nuclear DNAmolecules present in a human cell:a. Metaphase of mitosisb. Metaphase I of meiosisc. Telophase of mitosisd. Telophase I of meiosise. Telophase II of meiosis
Humans cells normally have 46 chromosomes (2n). Specify the number of chromosomes present at each of the following stages. In your answers, determine diploid or haploid number of chromosomes and the count the chromatids as chromosomes.
For example: anaphase I of meiosis: 46 (2n) = 92
a. metaphase I of meiosis
b. metaphase of mitosis
c. telophase I of meiosis
d. telophase II of meiosis
Using the symbols above:
1. Given: Adult diploid cell (2n = 8)
