True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
true
true the assortment is called genetic recombination
Yes, chromosomes are made of DNA and protein molecules called histones. Edit from another user: False, they're made of material called chromatin. Edit from user #3: Chromosomes and chromatin are actually the same thing, except in different form. Both chromosomes and chromatin are made up of a strand of DNA wrapped around histone protein, except chromatin is in a long and stringy form while chromosomes are a compacted and twisted version of chromatin.
Spindle fibers are thin tubes that form between the centrioles during mitosis. True..
a stage during mitosis consisiting of the regrouping of chromatides and string like chromosomes. In summery Chromosomes uncoil and revert to chromatin; nuclear membranes form around the sets of chromosomes.
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
False. The assembly of ribosomes begins in a small dense structure called the nucleolus, not the chromatin.
it's centromeres uncouple during metaphase of mitosis
true
False. A point mutation is a change in a single nucleotide of DNA, leading to a change in the protein encoded by that gene. The failure of a chromosome pair to separate during mitosis is known as nondisjunction, which can lead to chromosomal abnormalities in the daughter cells.
false
False
true
True. The nuclear membrane disintegrates during prophase of mitosis to allow the condensed chromosomes to be visible and function properly during cell division.
