How would 46 chromosomes fit in the nucleus?
The width of human cells range between 10-120 µm. … The length of the DNA packed into the 46 chromosomes of a bone marrow cell is around 46 000 times longer than the width of a cell. In order for all of this DNA to fit inside the nucleus of the cell it has to be packaged incredibly well.
Do germ cells have 46 chromosomes?
Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). … The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
