Ahuman bone marrow cell, in prophase of mitosis, contains 46 chromosomes. how many chromatids does it contain?

A human cell in prophase of mitosis contains 46 chromosomes with 2 chromatids each, which counts for a total of 92 chromatids.

Explanation:

In prophase, the first stage of mitosis (cell division), all 46 chromosomes have their chromatids duplicated. This is of key importance for the mitosis to happen correctly since these duplicated chromatids will separate and be part of the nuclei of the daughter cells that will be produced when the division ends. This way, each new cell will have an entire set of 46 chromosomes with 1 chromatid each.

the correct answer would be 6 feet.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
