Question
What must happen before meiosis can begin
DNA replication must come first before meiosis to happen.Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy. and a paternal copy.
Answer:
46
Explanation:
<u>The skin cells with 46 chromosomes will each produce daughter cells with 46 chromosomes after they complete the cell cycle.</u>
The skin cell is a vegetative cell that can only divide through mitosis. Mitosis is also referred to as equational division during which a cell produces two daughter cells that are both genetically and phenotypically similar to the parent cell.
<em>During the cell division, at the anaphase stage to be precise, the chromosomes are separated into sister chromatids and sister chromatids of the same chromosomes move in the opposite direction to the poles of the cell before the cytoplasm of the mother cell divides to produce two independent daughter cells. Each chromatid in the new daughter cells then goes ahead to become a complete chromosome with two sister chromatids.</em>
Hence, at the end of the cycle, each daughter cell ends up having the same 46 chromosomes as the parent cells.
The answer is D a nucleosome; a nucleosome has DNA wrapped around histones which prevents chromatin from tangling :)
C. they created the globe after they realized it was round
I think it is D. The National Institutes of Health found it effective in reducing pain and other symptoms, but it is not clear how it works.
